                              ----------                              


                      WEDNESDAY, DECEMBER 13, 2023

                      United States Senate,
                Subcommittee on Competition Policy,
                    Antitrust, and Consumer Rights,
                                Committee on the Judiciary,
                                                    Washington, DC.
    The Subcommittee met, pursuant to notice, at 3:02 p.m., in 
Room 226, Dirksen Senate Office Building, Hon. Amy Klobuchar, 
Chair of the Subcommittee, presiding.
    Present: Senators Klobuchar [presiding], Hirono, Welch, 
Lee, and Hawley.

            OPENING STATEMENT OF HON. AMY KLOBUCHAR,
           A U.S. SENATOR FROM THE STATE OF MINNESOTA

    Chair Klobuchar. All right. Thank you everyone for being 
here today. A few things on our agenda in Washington, but as we 
await word, like, you know, the white smoke coming from the 
Vatican to see if we have any kind of progress on an agreement, 
it does give us this pause in time to focus on a really 
important issue for our country.
    And so, I call to order the hearing of the Subcommittee on 
Competition Policy, Antitrust, and Consumer Rights. This 
hearing is titled, ``The New Invisible Hand? The Impact of 
Algorithms on Competition and Consumer Rights.''
    I'd like to welcome our witnesses. I got to say hi to all 
of you, and also, of course, Ranking Member Lee. Mike and I 
work together really well, and I appreciate his work, and his 
staff's work in working with our staff to plan this hearing.
    In today's digital economy, we are constantly interacting 
with algorithms, whether we're shopping online, paying rent, 
booking a flight, hailing a ride, buying insurance, or looking 
for a new app to download. Often, the products we see, the 
prices we pay, or the services we receive are determined by an 
algorithm.
    And I think even for some of our more astute visitors today 
to this hearing, and people who may be joining us, including 
Senator Hirono who just joined us, I don't think when we look 
at our phones and we see things pop up, that even when we know 
these algorithms are playing a role, do we really think that we 
are being manipulated by them?
    I think we think we're smarter than that, but actually, it 
is happening all the time. And so, the focus of this hearing is 
really what's going on, and how it is affecting competition and 
prices that consumers are facing.
    In many ways, the services that are built with algorithms 
can improve our lives. We know that algorithms help make sense 
of vast amounts of information to surface and order search 
results, identify patterns, and improve products.
    But algorithms also have the potential to create or 
exacerbate competition problems. Even when used with the best 
intentions, algorithms that are built with data that reflect 
past patterns of bias or discrimination can perpetuate those 
patterns into the future. And algorithms also are responsible 
for pushing harmful content to kids. Today's hearing will 
explore these issues to help Congress understand how to 
safeguard competition and protect consumers.
    In October, this Subcommittee heard testimony about the 
potential for competitors to use a third-party algorithm to fix 
prices in housing markets, driving up the cost of rent and 
leading to higher vacancy rates.
    Corporate landlords have figured out that it's better for 
them and their bottom lines to delegate their pricing decisions 
to algorithms to push rent so high that some rental properties 
sit empty rather than offering housing that people can actually 
afford. And they're doing this not the old-fashioned way by 
talking to each other, which would be clearly--some of this 
would be illegal depending on the course of conduct, but 
they're doing it by delegating it to an algorithm.
    As I said in October, landlords shouldn't be sharing prices 
in an effort to boost prices. Instead, they should be competing 
on price and on quality.
    Price fixing and other forms of collusion are illegal under 
the antitrust laws. When competitors that should be competing 
decide instead to delegate their independent pricing decisions 
to an algorithm, the result is little more than a sophisticated 
cartel hiding in code. Whether the conspiracy takes place in a 
server room or a boardroom shouldn't matter under the antitrust 
laws, but it isn't clear whether our current antitrust laws are 
sufficient to stop that practice.
    Most courts require proof of an explicit agreement to fix 
prices before condemning the conduct. But that agreement may 
not exist when a computer is coordinating prices instead of 
humans. It may even be possible for independent price-setting 
algorithms programmed to maximize profits to learn to collude 
on price without any human intervention.
    Price fixing isn't, of course, the only concern. Dominant 
platforms can and do use algorithms to preference their own 
products and services, and bury those of their competitors.
    The United States needs laws that are up to date, and as 
sophisticated as the monopolists we are trying to reign in. 
That's why Senator Grassley and I have introduced the American 
Innovation and Choice Online Act--you may have heard about it 
on TV. There was a lot of ads run against it. Hundreds of 
millions--which is co-sponsored by several Members of this 
Committee, and is specifically targeted to address this type of 
anticompetitive conduct by Big Tech platforms.
    Dominant firms may also use algorithms to protect 
themselves from competition. For example, the FTC recently sued 
Amazon for monopolizing e-commerce markets, in part, by 
surveilling prices across the internet and punishing 
independent businesses that sell on Amazon's marketplace that 
offer lower prices anywhere else. This conduct deters price 
competitions, hurts consumers, and gives Amazon free reign to 
charge exorbitant fees to small businesses that uses the 
platform.
    The public understands that Big Tech tactics hurt consumers 
and deter innovation. Just this week, a jury in California 
found Google's App Store policies--allowing it to take up to 30 
percent of a developer's revenue--violate antitrust laws. The 
Department of Justice has also sued Google for monopolizing the 
search engine market. The recent trials showed that Google's 
exclusive contracts, which guarantee its search engine default 
status, starved competitors of the data necessary to develop 
competing algorithmic search tools.
    And because algorithms run on data, the more the companies 
rely on algorithms, the more they will be incentivized to track 
consumers to collect data raising privacy concerns. This is why 
I've long supported comprehensive Federal privacy legislation 
so that consumers can control how their personal data is being 
used, including the right to opt out.
    Moreover, the output of an algorithm is only as good as the 
data fed into it. ``Garbage in, garbage out,'' as they say. 
This means that if an algorithm is trained on data that 
reflects racial, economic, or other biases, it can lead to bias 
or even discriminatory results. For example, after being 
trained on a company's past hiring data, an algorithmic tool 
used to screen job applicants weighed two factors most heavily 
when making recommendations about whom to interview: the name 
Jared, and the interest in lacrosse. True fact.
    Finally, the proliferation of artificial intelligence and 
machine learning has a potential to supercharge these issues 
and to create new ones. That's why earlier this week, Ranking 
Member Lee and I sent a letter to the Department of Justice and 
the FTC asking for more information about their enforcement 
efforts related to algorithms and additional tools they need to 
do that work.
    While many of these issues raise tough questions, I think 
one thing is clear. We need vigilant enforcement of our 
antitrust laws. We, of course, passed our Merger Filing Fee 
Modernization Act on a, I think, 88 vote in the U.S. Senate, to 
move up when that money was going to be collected to allow our 
antitrust enforcers to do their jobs, as well as passing 
Senator Lee and my Venue bill at the same time.
    So that is our part, but we know there's so much more we 
have to do, and that's why we're having this hearing today. I 
consider this the beginning of this discussion. We know there 
will be AI legislation coming down the pipe. We also know that 
many other Members in the Senate are interested in this, as 
well. So with that, I turn it over to Senator Lee.

           OPENING STATEMENT OF HON. MICHAEL S. LEE,
             A U.S. SENATOR FROM THE STATE OF UTAH

    Senator Lee. Thanks so much, Madam Chair. And that was a 
good day getting that passed. Wasn't it? We like that bill.
    As our economy continues to modernize, algorithms have 
drawn increased attention as a tool for calculating prices, and 
calculating costs, and doing all sorts of things that we would 
never have dreamed just a few short years ago could be made by 
reference to or with the assistance of an algorithm.
    Although algorithms are efficient, they can be used by 
businesses to collude in setting prices, and to reduce the 
quality of products in a way that can perpetuate bias. 
Algorithms are neither good nor bad, but rather, like a 
company's size, it depends on the context. It depends on how 
they are used.
    There's nothing inherently sinister about an algorithm. 
They can do only what they've been designed to do, and for that 
reason, we can fairly say that the devil is in the details. It 
depends on the quality of the data that's being fed into them, 
and what businesses do with the algorithms that may be 
problematic, especially if the business in question has 
monopoly power or engages in collusive price setting.
    Today's hearing concerns algorithms and their potential 
impact on competition. Now, it can be used in a number of ways 
that may impact competition, in ways that are either pro-
competitive, pro-competition, or anti-competition.
    First, algorithms are able to help determine prices. Using 
an algorithm is a much more efficient, and in some cases fast, 
perhaps accurate way to set prices rather than engaging in a 
more traditional, price-setting method.
    For example, consumers experience this when using, just to 
cite one example, popular rideshare apps. Algorithmic pricing 
could be very problematic if used improperly. When executives 
use algorithms to collude and to set prices, this can impede 
competition and undermine the natural balancing of the market. 
Algorithms present a new and easier way to engage in this 
behavior, and to engage in it in a way that makes its detection 
a little more difficult.
    Second, algorithms impact competition by affecting the 
quality of products. Facebook, Google, TikTok, Twitter, and 
others have been a sale for the content that their algorithms 
sometimes produce, or alternatively restrict, or throttle, or 
advance, or silence, or partially mute.
    These algorithms are likely written with the intent to fuel 
engagement and keep users on the platform to consume more and 
more content in a period of time, or to keep the user on the 
app for a longer period of time. It's the clickbait model, 
basically, but on a trillion-dollar societywide basis.
    Why fuel engagement? Why use the clickbait model, or 
something else, algorithmic, or otherwise, to fuel engagement? 
Well, more time spent on the platform means more digital ads, 
and that, in turn, as those eyeballs are scanning more and more 
ads, means a lot more money for the platform.
    Now, Google and Facebook are a digital advertising duopoly 
rife with all sorts of conflicts of interest. Those conflicts 
enable what basically amounts to insider trading, exacerbating 
the monopoly rents that Google and Facebook already collect, 
and further incentivizing those companies to keep people on 
their platforms for as long as possible.
    Breaking up the ad tech stack is an important first step 
toward reigning in the power of Big Tech platforms, and making 
sure that they don't use algorithms in an anticompetitive, 
predatory, harmful manner. Additionally, Big Tech companies 
have exploited algorithms to exert their market position in 
order to push content, perpetuate bias, and control expression, 
speech, and even elections.
    This even applies to what our children are viewing online. 
We can all agree, I think, that this is bad when it 
specifically happens to children, especially when Big Tech 
pushes inappropriate content to underage viewers, whether 
teenagers, or in many cases, much smaller children. They don't 
yet have the maturity, the judgment, the self-control to make 
wise decisions about the content that they consume. And in some 
cases, they can be really affirmatively harmed by it.
    All of us have the instinct to protect children. I believe 
that the effective enforcement of antitrust laws in this area 
could result in increased competition and new alternatives. And 
with those new alternatives, you could have some companies 
doing a better job than others at making sure that the content 
provided to children wouldn't be harmful to them.
    Now, this is also true of course, when it comes to adults. 
Neither the Government nor Big Tech should be telling people 
what to believe or how to vote, or at least should proceed with 
the knowledge that if they tell people what to believe or how 
to vote, they may have backlash in the marketplace, at least if 
there is a marketplace with robust competition to be had.
    Because if there isn't, they're going to continue to do 
whatever they want, relying on their monopoly or duopoly 
status, relying on the absence of meaningful competition, 
knowing full well that they can simultaneously advance their 
economic, you know, their financial, and their political, or 
other interests.
    It's nothing short of alarming that Google, precisely 
because of its monopoly and its lack of algorithmic 
transparency that impairs in the nature of the use of 
algorithms, can control the information that a user sees to the 
extent that it does with no repercussions in the market.
    According to Dr. Epstein's research, Google is feeding 
people biased information quite deliberately that it furthers 
the progressive political agenda and reminds liberals to vote 
on election day while intentionally failing to give 
conservatives those same reminders.
    Now, Google significantly ended the partisan vote reminder 
and began sending the vote reminder to all users, but only 
after they were caught doing so in the last election. That is 
significant. That is itself, perhaps, an indication that 
there's a breakdown in the market. That, perhaps, is an 
indication that the antitrust laws can have something 
meaningful to say here--and that they should.
    Now, I want to be clear, every American, including any 
business, has whatever right to pedal whatever sort of 
political message that that company, or that business, or that 
person may want, whether it's for a political party represented 
by an elephant, or one represented by a donkey, or for that 
matter, a giraffe. They can do that if they want. It's part of 
the First Amendment. They enjoy that First Amendment 
protection.
    But if they're doing that, especially doing that in an 
audience that doesn't consist overwhelmingly of Republicans, or 
of Democrats, or whoever they're trying to pitch these messages 
to, they would be doing so at the risk of alienating, in our 
country, about half the population anytime they side with one 
political party over the other. The fact that they did so, so 
boldly, so effectively, so unapologetically in this instance, 
to me, suggests there's something terribly, terribly wrong. We 
know that there is, in that marketplace. It's one of the 
reasons why we need to address the stack.
    We have an obligation to our constituents to protect them 
from this significant threat and to defend competition itself--
not for the purpose of any political party, or cause, or 
message, but because consumers themselves deserve better than 
this. They deserve what happens naturally when there is 
competition in the marketplace. I look forward to our hearing 
today and to hearing from each of you.

             STATEMENT OF HON. BILL BAER, VISITING

               FELLOW IN GOVERNANCE STUDIES, THE

             BROOKINGS INSTITUTION, WASHINGTON, DC

    Mr. Baer. Chair Klobuchar, Ranking Member Lee, Senator 
Hirono, it's good to be back. And thank you for the opportunity 
to address, as you both have noted, one of the many challenges 
we face in harnessing the power and maximizing the potential of 
AI.
    The growing use of pricing algorithm presents one such 
challenge. I'm no expert in AI, believe me. But from the 
vantage point of a long-term antitrust enforcer, I am concerned 
that misuse of this tool is growing and puts consumers at risk 
of paying supracompetitive prices for all sorts of goods and 
services.
    Sometimes competitors agree directly on a pricing 
algorithm. We brought a case when I was at DOJ that addressed 
that kind of competitor-to-competitor agreement. But often 
companies outsource to a third-party AI price fixing by using 
the same vendor to collect the data on supply and on demand, 
and recommend pricing or output behaviors that facilitate price 
coordination.
    Your hearing last October on rental housing markets showed 
how property management companies allegedly were using third-
party vendors to collect competitively sensitive pricing 
information from competitors, feed that data through 
sophisticated algorithms, and recommend unit-by-unit prices so 
landlords could charge higher rent.
    Similar antitrust challenges are pending involving hotel 
operators in Las Vegas and in Atlantic City, using that same 
kind of third-party pricing algorithm to suggest profit 
maximizing strategies to the hotels that increase margins and 
limit a consumer's ability to bargain hunt online.
    These AI-facilitated hub-and-spoke conspiracies extend 
further up the food chain, too, literally. This fall, DOJ and 
six attorney generals, including those from Utah and Minnesota, 
charged Agri Stats with operating an information exchange that 
obtained sensitive price and output information from turkey, 
chicken, and pork producers, analyzed the data, and provided 
feedback that allowed these competitors to reduce output and 
increase price with confidence that their competitors would do 
the same.
    Again, the basic behavior's not new, but the use of pricing 
algorithm seems to make coordination both easier and quicker. 
The good news is that these hub-and-spoke conspiracies have 
traditionally been held to violate the antitrust laws. The bad 
news is that algorithmic collusion using third parties seems to 
be on the increase. Detection is not easy, and AI makes success 
more likely,
    But my big worry is whether our current antitrust 
jurisprudence can handle fact patterns where the machines learn 
how to collude with little or no human involvement. An unlawful 
agreement under Section 1 of the Sherman Act requires a showing 
of a meeting of minds between rivals, a conscious commitment to 
a common scheme.
    At the same time, the courts have held that consciously 
parallel behavior, sometimes called ``tacit collusion,'' is not 
enough to violate Section 1. Courts require plus factors, proof 
that something more than parallel unilateral action was afoot. 
But what if competitors individually develop pricing algorithms 
that set profit maximization as the goal, and machine learning 
leads to pricing outcomes that result in widespread 
oligopolistic pricing in markets where discounting previously 
was the norm?
    I think about the 1983 ``WarGames'' movie. There, a young 
computer nerd, played by Matthew Broderick, hacks into the 
super computer controlling the U.S. military's nuclear arsenal, 
and activates a game called Global Thermonuclear War. He thinks 
it's just a game, but the computer, the Whopper, treats it as 
the real thing and takes actions that trigger escalating 
responses from the then-Soviet Union.
    We were on the brink of thermonuclear war until Broderick 
directs the computer to play tic-tac-toe. In seconds, the 
whopper--this is the 1980s--runs every series of possible 
moves, learns that the game is unwinnable, and stops the 
escalation.
    I worry about an algorithmic pricing scenario where 
companies individually write code that simply instructs the 
machine to profit maximize. The machine gathers public pricing 
info from competitors, learns in nanoseconds that price 
competition is eluding losing strategy, and it stops 
discounting, and stabilizes prices.
    Does the industry-wide implementation of pricing algorithms 
that predictably lead to such a result, even without direct 
communication between competitors, constitute and illegal 
agreement under Section 1? That's a little unclear under 
current law.
    So, what can be done? My written statement makes a couple 
suggestions.
    First, enforcers need to determine whether my doomsday 
scenario is actually a real-world concern. One way to do that 
is in merger investigations to make sure they use second-
request to see how the pricing algorithms employed by merging 
parties react to each other's pricing decisions.
    In addition, the FTC could use its authority in under 
Section 6(b) of the FTC Act to do a deep dive into selected 
industries and learn, better understand the prevalence and 
real-world impact of pricing by algorithm. The FTC potentially 
could employ its unfair methods of competition authority under 
Section 5 to challenge the use of AI that results in 
anticompetitive outcomes, even if the evidence is not 
sufficient to show an agreement in violation of Section 1. In 
addition, companies need to monitor the pricing behavior of 
their machines just as they're responsible for the actions of 
employees that lead to anticompetitive results.
    Finally, Congress, I think, should consider legislation 
that addresses the growing risks that competition posed by 
algorithmic pricing, either as part of this broader effort to 
set guardrails for the use of AI, or antitrust-specific 
legislation that holds competitor responsible for the knowing 
use of pricing algorithms that that they know or should have 
known results in tacit collusion and reduced competition. Thank 
you.

    Chair Klobuchar. Very good. Thank you. Mr. Hewitt--where we 
challenge you to cite a 1983 movie.
    [Laughter.]
    Chair Klobuchar. Go ahead.
    Mr. Hewitt. I've seen that movie, and it's a very good 
film.

          STATEMENT OF DAMON T. HEWITT, PRESIDENT AND

          CHIEF EXECUTIVE OFFICER, LAWYERS' COMMITTEE

           FOR CIVIL RIGHTS UNDER LAW, WASHINGTON, DC

    Mr. Hewitt. Good afternoon, Chair Klobuchar, Ranking Member 
Lee, Senators Hirono and Welch, and others in absentia. My name 
is Damon Hewitt, president, and executive director of the 
Lawyers' Committee for Civil Rights Under Law, where our 
mission is to ensure that Black people and other communities of 
color have the voice opportunity and power to ensure that all 
the promises of our democracy are made real, and not just words 
on paper.
    As technology grows in this country and plays a growing 
role, our work has expanded to include what we call ``digital 
justice.'' We're looking at the intersection of racial justice, 
privacy technology, focusing on the ways that predatory data 
practices, discriminatory algorithms, and other online harms 
disproportionately impact consumers of color.
    Across our economy, algorithms are used to make decisions 
about all aspects of our lives, determining who can run a 
house, who can get a loan, who can get a deal, and 
consequentially who cannot.
    One of the greatest civil rights challenges of our 
generation is to ensure that our new data-driven economy, does 
not replicate or amplify existing discrimination. As Ranking 
Member Lee said earlier in his remarks, AI is not the problem, 
but it's like putting discrimination and the problems that do 
exist on steroids if we don't watch out.
    We have to ensure that the technology well serves all of 
us. Because algorithmic technologies are built using societal 
data that reflect generations of discriminatory practices, such 
as redlining and segregation, they often reinforce past 
patterns of discrimination.
    For example, scoring algorithms used by auto insurers 
result in higher rates and fewer options for residents of 
majority Black neighborhoods who don't have other options. 
Retail websites have been found to charge different prices for 
the same products based upon consumer demographics. Mortgage 
approval algorithms are more likely to reject Black applicants 
even when they have less debt than white applicants. Things 
that absolutely make no sense.
    The harms of algorithmic discrimination are already denying 
millions of Americans equal opportunity in our economy. Instead 
of aiding consumers, AI tools often create gross distortions in 
the marketplace, reflecting exclusion rather than fairness for 
consumers and creating closed doors in the virtual world that 
have discriminatory effects in real life.
    In my written testimony, I catalog dozens of examples 
showing how algorithmic systems harm Black communities and 
other communities of color. Left unchecked, these harmful 
impacts will continue to grow as AI becomes ingrained in every 
aspect of our daily lives.
    Senators, my message today is simple: The tools of the 
future are locking us into the mistakes of the past. But it 
does not have to be that way. Congress must act quickly to 
enact legislation that can ensure algorithmic systems are safe, 
effective, and fair for all consumers.
    Now, we've faced similar challenges in this country before 
to unlock opportunity. Congress passed the Civil Rights Act of 
1964 to prohibit segregation and interstate commerce alongside 
other legislation to address discrimination in employment, 
housing, and other critical aspects of the lived experiences of 
daily lives of Americans in the marketplace.
    Today, the mass accumulation of personal data and the use 
of algorithmic technologies call for return to our civil rights 
legacy to ensure that everyone has an equal opportunity in the 
new digital marketplace and fair access to the information 
goods and services it enables. We believe at the Lawyers' 
Committee that legislation coming down the pike should reflect 
at least six key principles.
    First and foremost, AI regulations should protect American 
civil rights by including an explicit anti-discrimination 
provision that prohibits algorithmic discrimination.
    Second, AI tools should be evaluated and assessed for 
discrimination and bias, both before and after deployment. As 
Mr. Bayer mentioned earlier, these machines learn and they 
evolve. So, we can't just test one time. We need ongoing 
review, assessment, and audit.
    Third, developers and deployers of AI should have a duty of 
care requiring that products that they offer are safe and 
effective. As with any consumer product, the developers and 
deployers should be liable if these products are not safe and 
effective.
    Fourth, AI regulation should include transparency and 
explainability requirements so that consumers know when, how, 
and why AI is being used in a way that impacts them.
    Fifth, data protection requirements should limit the use of 
personal data and safeguard consumer privacy. Data protection 
is necessary to ensure that personal information is kept secure 
and not used against consumers unfairly.
    And finally, AI regulation should establish robust 
oversight and enforcement of mechanisms, empowering Federal 
officials with adequate authority and resources in providing a 
private right of action to remedy algorithmic harms in the 
private sector.
    We believe this type of legislation will help to limit 
discriminatory impacts of AI, and will be good for all 
consumers. Thank you. I look forward to your questions.
    [The prepared statement of Mr. Hewitt appears as a 
submission for the record.]
    Chair Klobuchar. Thank you very much, Mr. Hewitt. Dr. 
Epstein.
    Dr. Epstein. I'm going to turn on the screen. Oh great.

      STATEMENT OF ROBERT EPSTEIN, PH.D., SENIOR RESEARCH

        PSYCHOLOGIST, AMERICAN INSTITUTE FOR BEHAVIORAL

           RESEARCH AND TECHNOLOGY, VISTA, CALIFORNIA

    Dr. Epstein. Ms. Klobuchar, who's one of my very favorite 
of America's leaders because she's one of the few Members of 
Congress who has never taken a dime from Google. And Mr. Lee, 
who helped me and my team to get Google to back off in a 
national election. Thank you, sir, immensely. It's my first 
chance ever to thank you.
    Thank you, and other Members of the Committee, I'm here to 
tell you about an existential threat to our country that is so 
well hidden--I warn you, by the way, some of what might turn up 
on the screen in the next minute or two might be disturbing. I 
apologize in advance, but it's necessary that you see it.
    It's so well hidden that you might know nothing about it. 
It's a threat posed by Big Tech monopolies, eerily predicted by 
President Eisenhower in 1961.
    In 2016, Google alone shifted more than 2.6 million votes 
to Hillary Clinton--whom I supported--using subliminal 
techniques I had been studying and quantifying since 2013.
    Four days later, a leaked video showed Google's leaders 
devastated by Trump's win, telling their employees they would 
not allow Trump to win the Presidency again. They would 
guarantee his defeat through their, quote, ``great strength and 
resources and reach.''
    They made good on this promise in 2020, and in 2022, as I 
explained recently in The Epoch Times, they stopped the ``red 
wave'' cold. I lean left, but I don't think a private monopoly, 
one with no accountability to the public, should be able to 
pick our Nation's leaders.
    Who knows how these secretive companies will lean next 
year, after all. After that all-hands meeting, Google perfected 
at least a dozen new methods of subliminal control that I have 
now been studying, using rigorous scientific methods for more 
than a decade.
    To shift votes, we know from leaked emails, that Google 
relies on what they call ``ephemeral experiences''----
    [Large viewing screen is displayed.]
    Dr. Epstein [continuing]. Fleeting content such as search 
results, search suggestions, and UpNext videos on YouTube, 
content that impacts undecided voters and then disappears, 
leaving no paper trail.
    Since 2016, my dedicated team has been building 
increasingly more sophisticated monitoring systems that 
preserve and analyze ephemeral content. This is Google's worst 
nightmare, because it means we are surveilling them just as 
they surveil us and our children 24 hours a day.
    In other words, we are giving you, our Nation's leaders, 
the ammunition you need to finally hold Google and other tech 
companies accountable to the public.
    [Large viewing screen is displayed.]
    Dr. Epstein. Our research, which we publish in prestigious 
peer-reviewed journals, allows us to measure the power Big Tech 
has to shift votes, while our monitoring systems let us see 
whether these manipulations are actually being used. In one 
case so far, we shared our data with Senators Lee, Johnson, and 
Cruz. They sent a strong letter to the CEO of Google, which 
ceased some of its election manipulations that very day.
    It turned off the political bias in its search engine, and 
stopped sending partisan ``Go vote'' reminders on its homepage. 
Through our monitoring, we detected those changes the moment 
they were made. We preserve ephemeral content through the 
computers of a representative sample of real voters. One must 
monitor through the computers of real people because Big Tech 
sends out personalized content. To see what they're sending 
people, you must look over the shoulders of real people, just 
like the Nielsen company does with television viewers.
    Algorithms, my friends, I'm sorry to say, cannot be 
regulated because they are inherently opaque even to the 
programmers. And even if you did regulate, we still need to 
monitor to make sure there is compliance. We started small, but 
have deployed bigger systems with each election.
    In 2022, we preserved more than 2.5 million ephemeral 
experiences through the computers of more than 2,000 voters in 
10 swing States. We are now building the world's first 
nationwide digital shield, and we just released a public 
dashboard. It's at americasdigitalshield.com.
    [Large viewing screen is displayed.]
    Dr. Epstein. It's what you're seeing on your screen, and it 
shows our cumulative findings in real time as we are receiving 
the data. We are collecting and displaying data 24 hours a day 
through the computers of more than 13,000 voters in all 50 
States, and so far, we have court-admissible data in 15 States.
    We have thus far--excuse me, the extreme political bias we 
are seeing in content being sent to voters along with the 
highly sexualized and violent content being sent to America's 
kids confirm my worst fears: The technological elite, as 
Eisenhower called them, are now in control of our democracy, 
and they're systematically indoctrinating our children.
    If we can secure funding to expand our system so we have 
court-admissible data in all 50 States, the tech companies will 
back down in 2024. And even if they don't, we will have 
incontrovertible evidence of election rigging on a massive 
scale.
    If no monitoring system is in place, Google alone will be 
able to shift between 6.4 and 25.5 million votes in the 2024 
Presidential election, leaving no paper trail and making a 
mockery of the free and fair election. Thank you for your 
attention and for protecting our great Nation from threats, 
both foreign, and, I hope, domestic.

    Chair Klobuchar. Thank you. Dr. West, thank you.

STATEMENT OF SARAH MYERS WEST, PH.D., MANAGING DIRECTOR, AI NOW 
                 INSTITUTE, NEW YORK, NEW YORK

    Dr. West. Thank you, Chair Klobuchar, Ranking Member Lee, 
and to the Members of the Committee for inviting me to testify 
on this important set of issues. I deeply appreciate this 
Subcommittee's ongoing attention to the role of algorithmic 
systems in shaping the economy at large, often in ways that 
harm consumers while benefiting centralized actors.
    In the most basic sense, algorithms are simply instructions 
that computational systems follow. They frequently involve 
using statistical techniques and applying them to very large 
amounts of data to arrive at a decision. For example, 
processing personal data to tailor a price to the maximum the 
system predicts a buyer will be willing to pay.
    Now, while many of the underlying techniques have existed 
for decades, such systems are supercharged by the surveillance 
business model that's been promulgated by the tech industry. 
This drove the creation of technologies that collect detailed 
and often intimate information about us as we move about our 
lives. This business model produced information and power 
asymmetries that have profound societal effects.
    Now, firms that are positioned at key choke points in the 
economy are best positioned to leverage data in a manner that 
is harmful both to competition and to consumers. This creates 
extended potential for collusion in markets where this 
otherwise would not be possible.
    This is most visible when we see systems go awry, like when 
the price of hand sanitizers spiraled at the start of the 
pandemic. But frequently it takes shape in more invisible ways 
that are harder to identify from the outside. And my fellow 
witnesses have identified several examples in real estate and 
car insurance.
    This works the other way around, too, though. For example, 
Dr. Veena Dubal has studied the use of algorithmic models to 
determine the wages of rideshare drivers, which effectively has 
served to drive down their take-home pay across the board.
    What this means is that people are being placed in a dual 
bind. On the one side, they experienced personalized pricing 
that extracts as much money as possible from them, and on the 
other algorithmic, wage discrimination that drives down their 
pay.
    This is one reason why it's particularly crucial that we 
address concentration among the firms producing and deploying 
algorithmic systems.
    Another is to mitigate the risk of creating single points 
of failure that could have ripple effects throughout the 
economy. Over-reliance on the same algorithmic model can 
present imminent risks to financial stability. And these risks 
are not only posed to financial markets, but, you know, the 
more broadly a single system is used, the greater the 
consequences could be across housing, credit, payments, 
transportation.
    We all know that algorithmic systems are not infallible. To 
the contrary, where investigators have looked under the hood, 
they often find that the underlying data on which these systems 
are being trained is flawed, and this leads to widespread 
errors in decision-making. Think about the frustration of 
having an insurance claim be denied just because the evaluator 
on the other side was in a rush, or hadn't had their coffee yet 
this morning.
    We can think of algorithmic systems as taking each of those 
individual decisions and replicating them at massive scale, 
often with little to no scrutiny before they've been 
commercially deployed. We've granted a staggering amount of 
power to the scant few firms that have the data and 
computational infrastructure required to develop and deploy 
algorithmic systems, and we've given up consumer sovereignty in 
the process.
    The opacity of algorithmic systems also makes effective 
enforcement all the more difficult. By denying the public 
information about how algorithmic systems are affecting their 
lives, each of us lacks the information that we would need to 
be able to understand whether a decision's accurate, to whether 
we have means to seek remedy or how to push back. And this is 
why effective regulatory intervention that foregrounds bright-
line measures is particularly needed in this moment.
    To conclude, there are three paths forward that I'd like to 
particularly highlight.
    One is, we need to use existing enforcement mechanisms to 
ensure strong oversight of algorithmic systems, and robustly 
enforce the agencies that have the existing authority.
    We already have a range of laws in place that can be 
applied to anticompetitive and harmful uses of AI and 
algorithmic systems, and we need to make sure that our 
enforcers have what they need to meet that challenge.
    Second, we need specific bright-line rules to curb AI use 
where it has demonstrated harms to consumers and competition. 
As an example, the passage of a Federal data privacy law, 
including a strong data minimization mandate, should be an 
urgent priority here.
    Last, we need legislation that will tackle the market 
structure and gatekeeper power of dominant digital platforms, 
which hold an unprecedented amount of economic and political 
power. Thank you very much for your time, and I look forward to 
your questions.
    [The prepared statement of Dr. West appears as a submission 
for the record.]
    Chair Klobuchar. Thank you. Professor Alford.

            STATEMENT OF ROGER P. ALFORD, PROFESSOR

          OF LAW, UNIVERSITY OF NOTRE DAME LAW SCHOOL,

                      SOUTH BEND, INDIANA

    Professor Alford. Chairwoman Klobuchar, Ranking Member Lee, 
and Members of the Committee, thank you for inviting me to 
testify today to discuss the impact of algorithms on 
competition.
    Let me begin by just saying that this is a matter that is 
both a global concern and a matter of bipartisan concern. When 
I was at the DOJ, I traveled the world, and it was rare to go 
to an antitrust conference where there was not discussion about 
the monopolization abuse of Big Tech companies.
    Likewise, here in the United States, the Trump 
administration, and the Biden administration, and almost every 
State attorney general have filed landmark antitrust litigation 
against Big Tech.
    Both Senator Hawley and Senator Klobuchar have written 
books expressing grave concern about Big Tech abuse of power. 
Senators across the political spectrum have expressed this 
concern.
    In my written statement, I provided quotes of different 
Senators from this Committee, and, unless you look at the 
footnotes, it's hard to know which side they're on, in terms of 
their expression of concern. Much of the concern relates to how 
Big Tech has harnessed algorithms to exert market power like 
never before in history.
    Despite the obvious benefits of algorithms, which we can 
all concede, their emergence creates enormous risks for the 
abuse of monopoly power, and is a facilitating factor in 
collusion between competitors. The algorithms themselves 
recognize that they pose a risk to competition.
    When I typed in the query, ``How do algorithms harm 
competition? '' ChatGPT unabashedly confessed to me that 
algorithms can harm competition in several ways, and then it 
offered a half dozen different ways that it, algorithms, can be 
harmful. It then concluded with a warning to lawmakers that the 
fast-paced nature of technology often outpaces regulatory 
measures, which I think this Committee should take as a 
challenge.
    With respect to price fixing, we've already talked about 
different examples. Most recently in the RealPage case, the 
Department of Justice has declared that weather firms 
effectuate a price fixing scheme through a software algorithm 
or through a human-to-human interaction should be of no legal 
significance.
    The RealPage example is but one that you have already had a 
hearing about. Other examples in price fixing, we know from 
2016 that there was a criminal investigation and prosecution of 
sellers on Amazon Marketplace that led to a conviction with 
respect to price fixing through algorithms.
    And then, also just most recently with the JetBlue-Spirit 
merger, information signaling through, so-called flashing is 
happening where you're signaling to competitors what your 
pricing behavior should be, and basically encouraging your 
competitors to change your pricing behavior. All of those are 
examples have different types of price fixing through 
algorithms.
    According to the DOJ Justice Surrendering and Freedom of 
Action, and agreeing to abide by the will of a trade 
association--which by the way I was involved in, in the recent 
real estate price fixing. I as an expert witness in which $1.8 
billion was awarded against the National Association of 
Realtors--we know that following the trade association rules 
should be viewed as and frowned upon.
    The same is true with respect to algorithms. Concerted 
action by an algorithm and reliance on a joint algorithm 
generates price collusion.
    With respect to monopoly abuse, there's so much to be said. 
I encourage you to look at my written comments, but let me just 
make a few quick comments about monopoly abuse through 
algorithms.
    In the Federal Trade Commission's complaint against Amazon, 
Amazon algorithms detected if a seller offers a lower price on 
any other online store, anywhere on the internet, and it would 
punish those sellers on Amazon by disqualifying the seller from 
utilizing the ``Add to Cart'' or the ``Buy Now'' button.
    I don't even know how to buy anything on Amazon without the 
``Add to Cart'' or the ``Buy Now'' button, but if you do have 
any price competition anywhere, then you basically will be 
taken off of that opportunity. And in Amazon's words when they 
do that, the sales of those sellers tank.
    With respect to Google search litigation, I think we've all 
been riveted by the recent litigation that's happened here in 
DC against Google on search. We know that Google denies 
competitors the opportunity to scale. That was the essential 
argument what was happening with respect to those revenue 
sharing agreements. Google wants consumers to reach the 
conclusion that their competitors are inferior. They use a less 
polite word than that, and it will spend billions to control 
upstream inputs to deny its competitors the opportunity to 
improve.
    How it does so is simple. Search algorithms require query 
and click data to train the algorithms to improve search 
quality results. And in 2021, Google paid over $18 billion to 
Apple--or 36 percent of its mobile annual ad revenue--to be the 
default searching engine of Safari, and we know what happened 
with Bing in terms of their search capabilities. Their mobile 
search capabilities are far inferior to their desktop.
    Finally, with respect to Google ad tech litigation, we know 
that Google uses algorithms to rig auctions in the digital 
advertising marketplace. Because of Google's involvement and 
dominance on the buy side, and the sell side, and the 
exchanges, and in the middle, it has information advantages and 
uses those advantages to exploit it to its own benefit.
    My time has run out. Let me just conclude with a 
recognition that both Senator Lee and Senator Klobuchar had won 
great success last year, and that was the State Antitrust Venue 
Act. And I just want to thank you for that. We finally are back 
in Texas after 2 years of languishing in New York because of 
the work that you've done, and that's been a significant impact 
on the litigation that we've been pursuing against Google.
    And then finally, the legislation that was attempted last 
year, the AMERICA Act of S. 1073, I think that that is a great 
solution. It's attempting to do much of what the litigation is 
trying to do, and I commend you for that legislation as well. 
Thank you.
    [The prepared statement of Professor Alford appears as a 
submission for the record.]
    Chair Klobuchar. Thank you very much. I'm going to have 
Mazie Hirono take my place. She's been diligently here to go 
first, so thank you.
    Senator Hirono. Kind of you, Madam Chair. Thank you very 
much. So, listening to all of you, we know that algorithms are 
being used in many different ways, and it is very hard to keep 
track at the--I feel very--how shall I say? At a loss, as we 
have to navigate the waters that are before us.
    So, one consideration would be, perhaps, that we should 
have maybe at this point a dedicated digital platform 
regulator, this for Mr. Baer, and so maybe a competition 
promoting regulator who could act in this space the way the FCC 
did, and what is it--Carterfone back in 1968.
    So, do you think we should be considering a new dedicated 
digital platform regulator? Or would resources be better spent 
bulking up our current antitrust enforcers? Do you have 
anything to say about that?
    Mr. Baer. I always have things to say in just about 
everything, whether they're thoughtful or not. I do think that 
serious consideration ought to be given to a digital regulator. 
Whether that's a better idea than simply enhancing the FTC's 
authority to do it, it seems to me an open question.
    One of the cynical observations I'd make is, we've seen 
companies like Facebook, Meta, Google, others say, just tell us 
what the guardrails are. Give us some perspective guidance, you 
know. And there was a huge Facebook PR campaign a couple years 
ago about that. But the minute anybody puts something on the 
table, suddenly it's ``Katy, bar the door,'' and we can't do 
that.
    So, I do think looking, though, for some prospective 
guidance so that companies that want to behave, are able to 
train their employees to behave, is worth doing. Antitrust 
enforcement, other than mergers, is always after the fact. And 
it takes a long time for the enforcement to catch up with the 
conduct.
    So, in this area, given how fast paced it is, as a number 
of my colleagues have observed, trying to find a way to get out 
front makes a lot of sense.
    Senator Hirono. I think that is the concern that so many of 
us have, that things are moving so quickly that whatever 
regulatory framework we can put in place is already outdated by 
the time we figure out how to regulate in this space.
    So, Mr. Hewitt, you gave a lot of examples of how there can 
be all kinds of discrimination happening with the use of 
algorithms. And I am worried about the potential, more than 
potential for making discrimination into algorithms, especially 
if the algorithms are going to be used for things like lending.
    And you already mentioned that, you know, in the space of 
housing discrimination, there are all kinds of discriminatory 
decisions that can be made and that people are not even aware 
that it is happening. But it's through the use of algorithms.
    So Fair Housing lending--there are Government testers, for 
example, or shoppers who apply for housing and loans in order 
to root out potential discrimination. How important is the 
testing, to this kind of testing, to uncovering discrimination 
in the housing and lending context where algorithms may be at 
play?
    Mr. Hewitt. Well, thank you, Senator Hirono. Testing is a 
classic, you know, time-honored, tried-and-true technique that 
helps to build an evidentiary basis in all sorts of civil 
rights litigation and enforcement with respect to public 
accommodations in general. I believe the Department of Justice 
used testing online to effectuate its charges and settlement 
with respect to Meta or Facebook.
    I would also say, however, that as important as testing is, 
we would need millions of testers to keep pace and keep up. 
Which is why we need also legislation that compliments the 
testing, legislation--regulation that is a prophylactic that 
requires beforehand testing.
    Not testing only in the marketplace, but testing 
beforehand, almost akin to an environmental impact assessment. 
We wouldn't disturb the environment or an ecosystem before 
having some analysis of the impacts. And so I think that would 
be a perfect complement to testing, even though testing, as you 
indicated, remains critical and important.
    Senator Hirono. And I think that--doesn't the Supreme Court 
have a case that could set aside the ability of nonprofits and 
others to engage in testing?
    Mr. Hewitt. If you were referring to the----
    Senator Hirono. I think there's a case.
    Mr. Hewitt. The Atkinson hotels case.
    Senator Hirono. So, we have to worry about that. And I know 
that you notice some of the parameters that you would like us 
to consider for legis--regulatory legislation. So, I hope we 
can come up with something in this space, even if it's fast 
moving and complicated. Thank you, Madam Chair.
    Chair Klobuchar. Thank you. Senator Lee.
    [Pause.]
    Chair Klobuchar. They're like an Olympic commentary. 
They're saying, ``Well, he's preparing now. He's coming down to 
the floor.''
    Senator Lee. Thanks so much, Madam Chair. I really enjoyed 
your opening statements. Thank you for that.
    Professor Alford, I want to start with you, if that's all 
right. In 2024, both the DOJ and the State attorneys general 
are going to have trials regarding Google's abuse of its 
monopoly power, specifically in the ad tech market. Can you 
discuss with us just a little bit about how legislation in the 
ad tech market might be part of the solution in addition to 
litigation?
    Professor Alford. Sure. Yes. So, as you said, in 2024, we 
anticipate that the Department of Justice ad tech case, as well 
as the--we can anticipate, as I said, in 2024, the DOJ ad tech 
case, as well as the State AG ad tech case, led by Texas, will 
go to trial.
    But, as we've seen already from the past few years, there's 
extraordinarily hurt--extraordinary hurdles associated with 
those two cases. Extreme delay, complete denial of any sort of 
wrongdoing whatsoever, the exercise of privilege abuse that 
Judge Donato recently called was a frontal assault on the 
administration of justice.
    And so, we know that the--and even if there is success, the 
likelihood of a full structural remedy that would actually 
correct the market in the way that it should, is a best case 
scenario. So you're--the legislation----
    Senator Lee. That's compounded by some of the dynamics that 
we're describing----
    Professor Alford. Exactly.
    Senator Lee [continuing]. The inherent difficulty in 
understanding what's happening within the algorithm.
    Professor Alford. Exactly, exactly. So, the legislation 
that you proposed, S. 1073, the AMERICA Act, goes to the heart 
of the concerns in the DOJ litigation and in the State AG 
litigation, which is to recognize the conflicts of interest, to 
have one company or a set of large companies have a control 
over the buy side, control over the sell side, and control over 
the exchange in the middle, and basically use that information 
to advantage itself and to harm its own clients is just 
fundamentally problematic.
    It's not the kind of thing that we see in other markets. 
And so, the bill that you've proposed is essentially attempting 
to get at that issue, and particularly for the very largest 
ones.
    With respect to the middle tier companies, your legislation 
tries to do something, which is essentially provide more 
transparency obligations to act in the best interests of their 
clients rather than their own interests. So, it's a very 
salutatory development, and I hope that there's hearings and 
votes on that legislation.
    Senator Lee. So, in other words, would it be fair to say 
that--well, existing authorities--enforcement and litigation 
under existing authorities may well be capable of addressing 
the problem in this particular environment with algorithms and 
what you can use them to do in the marketplace may take so long 
to get to the result that you want, that it may become 
obsolete, and therefore not ideally suitable to deliver the win 
for competition and therefore the consumer that you need.
    Professor Alford. Yes. And also, I should add that, you 
know, the complaints are over hundreds of pages, and you can 
only try so many of the core issues in those cases. And so the 
legislation can, I think, get at more problems than simply what 
the litigation will be able to get to.
    Senator Lee. Now, it can be a little bit challenging to 
digest the true scale of these digital markets and to 
comprehend the vast impact that they have on our society and 
our internet economy. Can you offer any insights in that 
regard, help us to understand that?
    Professor Alford. Sure. So, you know, I've been working on 
the State AGs case against Google for years now, and there's a 
lot of different things one could highlight.
    But essentially, you know, if you control the information 
and you control the inventory that is provided to the 
exchanges, you can do a lot of things through algorithms that 
no other competitor can do.
    You can sequence when the bidding happens so that you get 
the first bids. You can peek at the information that is being 
offered in bid on other exchanges, and then you can adjust your 
pricing behavior so that you will win the bid simply by 
offering a penny less.
    So basically, you'll starve the other exchanges from 
competition just by peaking insider trading--I guess you could 
call it, and then using that, you can offer it advantages that 
are only available if you go to their exchange, like real time 
bidding.
    And so, you can do things like uniform pricing behavior 
where there might be that sellers want to go with another 
exchange, and they'll have different ceilings and different 
floors, but Google will impose uniform pricing behaviors so 
that's impossible to do that. So the whole range of different 
things that are happening with respect to the abuse of this 
monopoly power.
    Senator Lee. Now, one could argue that the same things in 
an environment where there is robust competition, those same 
things could maximize consumer welfare by bringing, you know, 
bringing up price, bringing down price, and increased quality 
all at the same time. Because if it operates in an efficient 
marketplace, it's make--makes an efficient marketplace in which 
there is robust competition even more efficient.
    Can you talk a little bit about how artificial intelligence 
itself might be made to thwart that? What are some of the 
competitive risks of Big Tech in, specifically, in the emerging 
AI space?
    Professor Alford. So, with respect to artificial 
intelligence, it's extremely new. It's extremely emerging. But 
we know several things. One, the startup cost and the barriers 
to entry are extraordinarily high. Unbelievably high
    Senator Lee. Just because of the computing power?
    Professor Alford. The sheer computing power. The 
information that you need to have inputs into the database, the 
training data, the cloud storage alone is just astronomical. 
And the potential for mistakes if you don't have sufficient 
data are enormous. The parlance, of course, is hallucination.
    But if you actually, like, dig down to what is a 
hallucination, that's what happens when the training data is 
insufficient, and it hasn't been asked that question before in 
the information data and so it overfits, is the language that 
they use.
    Senator Lee. Meaning it makes stuff up.
    Professor Alford. It makes stuff up, exactly, but that's 
because of the insufficient data. So, you can well imagine that 
the data brokers, that those that control the data are going to 
have the advantage in, within the AI space and new entrants, 
new emerging players are not--are going to have extreme 
difficulty trying to have the sufficient amount of data to be 
able to compete.
    So, the similar problems that you're seeing in Search where 
there's just not enough data for tail queries to be successful 
on Bing, that kind of thing could happen with respect to AI, as 
well.
    Senator Lee. It'd be good if they could give us a warning 
when it's hallucinating, play a Pink Floyd song, or something 
like that.
    [Laughter.]
    Senator Lee. I don't know. All right. My time's expired.
    Chair Klobuchar. Or use a watermark. Okay. All right. Thank 
you very much, Senator Lee.
    Mr. Baer, when you led the DOJ Antitrust Division, you 
brought, as you pointed out, the division's first-ever 
prosecution of price fixing case involving algorithms. The 
challenge is presented by algorithmic pricing. I have only 
become more acute, as we've all, a number of us have pointed 
out. What challenges do enforcers face today when attempting to 
bring the cases against groups of competitors that use 
algorithmic price setting tools to increase prices?
    Mr. Baer. The first problem, the biggest problem is simply 
detection. This case we brought, in 2015, involved two sellers 
of poster art on the Amazon Marketplace. They apparently 
concluded that there was too much price competition. They got 
together, the two companies in London, and wrote code that 
would basically--when anyone searched for poster art, these two 
would pop up in random order, but always at the same price.
    That's hard to detect. How do we find it out there? I think 
it's fair to assume that one of the companies did an internal 
audit, found out it was involved in this scheme----
    Chair Klobuchar. I see, they reported----
    Mr. Baer [continuing]. And came in and ratted themselves 
out. That doesn't happen all the time. In fact, it happens very 
little of the time. So, it is really----
    Chair Klobuchar. And you also don't always have the two 
people writing code in London. So, what are they doing now?
    Mr. Baer. So, you know, that--the worry, as I talk about in 
my testimony, is that you may be able to get to the same result 
if everybody just writes code that is roughly comparable, and 
the machines who can gather data in nanoseconds can figure out 
that cutting price over the long run is a losing strategy. And 
so, the worry is, independent decisions by firms in the same 
market may result in massive spread of anticompetitive pricing. 
That's the worry.
    Chair Klobuchar. That's because they're able to, so they 
all--they don't really want to reduce prices. So they--even 
though that's what competition is about, the reason you reduce 
prices to get more customers. But they can figure out through 
the algorithms well, where they don't really need to increase 
the prices. Is that where it is? Like--so explain it to me.
    Mr. Baer. Yes. The notion is that if the machines learn 
that if I discount, somebody else's pricing algorithm is going 
to price below me, and I'm going to quickly realize whatever 
gain I got from that initial price reduction goes away and the 
Pareto optimal prices is going back to something that is less 
competitive. I mean, to me that's what antitrust is all about. 
Finding fact patterns where consumer interests diverge from 
company self-interest.
    We've seen it in oligopolistic markets over time that firms 
independently figure out if we just track each other's pricing 
and don't compete, we're better off. With pricing algorithms, 
it's quite possible rather than having a concentrated two, 
three, four-firm market that the algorithms themselves, the 
machine learning will enable everybody to figure out price 
gutting isn't good for the bottom line even though it is good 
for consumers.
    Chair Klobuchar. Yes. So how can Congress ensure that 
courts properly evaluate cases involving the algorithmic price 
fixing where an agreement's difficult to prove?
    Mr. Baer. So, I think the first instance, as I said in my 
testimony, I think the antitrust agencies need to develop the 
data that establishes this is going on.
    You know, antitrust law evolves through common law and to 
point out situations that aren't reached by the current 
interpretation of what constitutes an agreement, what are the 
plus factors from which a court can infer a meeting of the 
minds, the knowing use of the same kind of pricing algorithm. 
If we can demonstrate that's going on and it has an impact, we 
can, as enforcers, encourage the courts.
    But it may well be that's not going to be enough. And it 
may well be that there needs to be legislation. It's a subtle 
tweak to Section 1 of the Sherman Act, but that basically 
directs the courts to take into account the anticompetitive 
impact of common use of pricing algorithms in the same market.
    Chair Klobuchar. Yes, we tend to be able to handle subtle 
tweaks better than other things. So, thank you.
    The FTC, Mr. Alford, recently sued Amazon for illegally 
monopolizing e-commerce related markets. Part of the allegation 
center on Amazon's use of price-scraping tools and algorithms 
that punish small businesses, relying on algorithms on Amazon--
not algorithms--for setting lower prices off of Amazon. Can you 
explain how these anti-discounting pricing algorithms harm 
competition and increase prices?
    Professor Alford. Yes. So, the Amazon complaint, I think, 
is incredibly well written and useful, and they talk about a 
variety of different behaviors. But with respect to the 
algorithmic behavior, I think there's two key things to note. 
One--and both of them is with respect to sellers and the way 
sellers behave on the Amazon platform and then off the Amazon 
platform.
    With respect to on the Amazon platform, it monitors what 
third-party sellers are doing. And anytime a third-party seller 
on Amazon lowers the price, then Amazon will match that price 
exactly.
    And the reason that they do that is because they want to 
make sure that third-party sellers don't get any sort of 
increase in market share. And then it basically dissuades any--
there's no incentive to lower your prices----
    Chair Klobuchar. Or increase prices----
    Professor Alford [continuing]. Because whatever price you 
offer, Amazon's going to go down there.
    Chair Klobuchar. They're going to beat you, and they're 
going to beat you in a big way when they do it.
    Professor Alford. That's right.
    Chair Klobuchar. They have the information.
    Professor Alford. That's the first thing that they do. That 
they basically disincentivize any sort of price competition to 
increase market share.
    The second thing they do is what I said already in my 
opening remarks, and that is they eliminated, under pressure, 
the price parity clauses in the contracts, and yet they create 
a punishment mechanism for Amazon, where if you sell your 
product on a third-party website, including perhaps your own 
website, your own company website, at a price lower than what 
is available on Amazon, then they're going to punish you by 
preventing you from accessing the key feature that everyone 
uses to buy stuff on Amazon, which is the ``Buy Now'' or the 
``Add to Cart'' feature.
    You can't get on there if you offer a lower price on 
Target, or Walmart, or any other website online.
    And the result of that, because of 98 percent of all Amazon 
sales use an ``Add to Cart'' and ``Buy Now'' feature, the sales 
of those third-party sellers tank. In my written remarks, I 
said that it's like Amazon in this respect is like the 
predators in the sci-fi movie, ``A Quiet Place''--if we're 
going to use movie references--where they'd seek to destroy any 
Amazon seller that dares to utter the sound of price 
competition.
    [Laughter.]
    Chair Klobuchar. Very good, very good. And, I mean, one of 
the extraordinary things about that complaint and the FTC, I 
thought that when they put it out there, it was pretty 
understandable, actually. One of the things that just stuck 
with me was that 50 percent of the small business revenue was 
going to them----
    Professor Alford. Yes.
    Chair Klobuchar [continuing]. You know, because they have 
no choice and they have to advertise.
    Mr. Hewitt, another issue related, algorithms can 
perpetuate past patterns of bias and discrimination, which you 
well illustrated in your testimony. This can result in fewer 
options, higher prices for historically underserved consumers. 
What commercial uses of algorithms concern you the most when it 
comes to perpetuating bias and discrimination against 
underserved consumers?
    Mr. Hewitt. Thank you, Senator Klobuchar. I would say 
housing and auto insurance are two that really stand out--and 
housing in particular, the mortgage market. I mean, so many 
Americans are priced out these days, ostensibly because of 
housing stock availability and also interest rates.
    But even when folks are trying to get a loan, we've seen 
research indicating that when algorithms determine what 
mortgage rates should be, that we see home buyers--prospective 
home buyers of color essentially blocked out and iced out. It 
creates this big distortion in the market. And so, it actually 
leads to this cascading sense of, ``Well, I can't afford it.'' 
``They're not going to allow me to afford it.'' And, ``Being a 
homeowner isn't even within reach for me.''
    With respect to auto insurance, there are companies that 
have tried to use geographic location as the means to determine 
what types of rates you will--you will receive. And so, if you 
think about it, if you happen to be a Black person living in a 
majority Black neighborhood, you're going to get sometimes 
higher rates quoted for you than somebody who lives in a 
neighborhood just a mile away. It doesn't make market sense in 
our view.
    And so, the whole notion of competition which is within 
this Committee's, you know, ambit, really gets turned upside 
down. Because how can you have real competition when you have 
some subsegments of the consumer marketplace who don't even 
have real choices at all?
    Chair Klobuchar. Mm-hmm. Well said. All right. I've gone 
way over my time here.
    So--do you want to let Senator Welch go, and then--okay. 
He's been so good sitting there. So, we'll have Senator Welch 
go next, and then I'm sure Senator Lee and I have questions for 
you, as well. Thank you. Well, go ahead.
    Senator Welch. Yes. I'll be brief. This is an incredible 
hearing. You know, people think the fix is in, but they don't 
really know how. And you're explaining how it is, and it's 
really pretty astonishing how small business folks are getting 
so incredibly ripped off.
    So, I want to thank you for the clarity of your 
presentation, and the deep work behind that. And I want to 
thank Senator Klobuchar and Senator Lee. I mean, the Senate 
needs to be dealing with this, and you're the leaders on this. 
So, I express my gratitude for that.
    You know, you've been talking--actually, you, Mr. Hewitt, 
and Mr. Baer, about housing. It is a brutal problem. Incredible 
in Vermont, nobody can live anywhere close to where they work. 
It's really tough--that affordability crisis is real, not just 
in housing. You mentioned auto insurance, but it's pretty much 
everything. You just got to take what you--you don't have any 
bargaining power at all.
    And housing, do you remember that algorithm, it was called 
Rent Maximizer? That was before they realized maybe we 
shouldn't advertise what we're doing. And they changed--they 
changed the name, but not the game. And all these companies 
have been able to evade the antitrust laws, the significant 
part because the antitrust laws just didn't anticipate--and how 
could they--the world we're in with digital commerce.
    So, Mr. Baer, I'll start with you. Just be specific, if you 
can, about how our antitrust laws cover any competitive 
behavior like this, and what do we have to do with respect to 
our antitrust laws and legal standards to address the reality 
of this anticompetitive behavior with a different tool? You 
know, ``Bob isn't doing it,'' as you mentioned, but it's 
happening with the algorithm.
    Mr. Baer. Right. So, I think, first of all, some of this 
behavior is being reached by not just the public antitrust 
enforcers, but by private plaintiffs who are acting on behalf 
of hotel customers, on behalf of apartment renters. So, there 
is some movement. The challenge is when, as I indicated 
earlier, competitors are independently and knowingly using the 
same type of algorithm without writing it together, that 
produces the same results as if they had sat down in London----
    Senator Welch. So, what can we----
    Mr. Baer [continuing]. Together, had a drink, and written 
the mass. So----
    Senator Welch. What can we do about it?
    Mr. Baer [continuing]. That's the problem.
    Senator Welch. I mean, you've got, you know, one of the 
most conservative Senators in the Senate, you know, Senator 
Klobuchar, and you've got one of the most liberal, Mr. Lee, 
right here.
    [Laughter.]
    Mr. Baer. Yes.
    Senator Welch. Or did I get that wrong?
    Mr. Baer. Well, maybe not on this one.
    Senator Welch. But they're both here because they share 
this common concern. So, what's your recommendation on one of 
the remedies we should pursue?
    Mr. Baer. So, I think encouraging the FTC to consider use 
of Section 5, unfair methods of competition authority, to 
bridge the gap between overt collusion and this sort of 
indirect collusion is one thing. If the courts aren't going to 
embrace that, and we don't know that they will, I think there 
needs to be a legislative solution----
    Senator Welch. Let me go to Dr. West, because I only have a 
little time. Can you discuss some of the risks surrounding the 
data collection, and whether or not and why you think a user 
should have to give their express informed consent before an AI 
system harvests their data?
    Dr. West. So, you know, data is a really key source of 
power for the firms that are engaged--talk button. Data is a 
key source of power for the firms that are using algorithmic 
pricing. It's what gives them these information asymmetries 
that let them, you know, exact as much out of consumers than 
they would otherwise. It's also what enables them to deny other 
competitors that lack that data advantage access to the market.
    So, you know, given this, you know, there's a feedback loop 
in that it creates strong incentives for firms that are 
utilizing these tools not only to the leverage the data that 
they have, but to continue to collect and retain as much data 
as possible. And that's why bright-line rules like data 
minimization are particularly key.
    Senator Welch. Thank you. Mr. Hewitt, can you discuss the 
impact of collecting mass user data, especially without 
receiving that informed consent that Dr. West is talking about? 
How does that affect lower income communities?
    Mr. Hewitt. Sure. Well, the companies that rely heavily on 
algorithms, especially whether it be social media or others in 
the consumer space, more squarely, they think they're holding 
up a mirror to us, showing us who we are. When in fact, it's 
really more like a fun house mirror. It's distorted. It's 
giving a distorted picture, and it's essentially trying to tell 
us who we are.
    And the driver of that story about who they think we are is 
based upon what Senator Klobuchar said in her opening remarks, 
``garbage in, garbage out'' data that is based upon a history 
of redlining and discrimination.
    It doesn't just so happen that our communities 
residentially are de facto segregated. It's because they were 
once digitally segregated. It's because of prohibited redlining 
practices and now we have digital redlining. That's 
essentially--that's what's been happening.
    And so, if all of our data is based upon explicit or 
structural discrimination, then we can't make that be the 
driver of all reality going forward.
    Senator Welch. Thank you very much. And by the way, my 
first job in law school was with the Lawyers' Committee for 
Civil Rights Under Law.
    Mr. Hewitt. How about that?
    Senator Welch. Yes, it's something. Thank you.
    Mr. Hewitt. Thank you for your service.
    [Laughter.]
    Chair Klobuchar. All right, well thank you very much, 
Senator Welch. Senator Lee, you have some follow-ups.
    Senator Lee. Thank you. Dr. Epstein, I'd like to go to you 
next. America's Digital Shield project has, I think, it's over 
13,000 field agents. I see you're nodding your head, I'm in the 
ballpark, that allow the collection of data to recreate 
authentic online experiences.
    And it's my understanding that it operates in a manner 
that's designed, maybe, kind of, to replicate or exceed the 
capabilities of the Nielsen research data system, with the 
latter system referring to TV viewers of course.
    It's different when you're dealing with the internet 
because it's much broader, much more--it moves much more 
quickly. Can you explain a little bit how you analyze this data 
to reach some of the results that you're looking for and how 
you go about that?
    Dr. Epstein. Yes, but first I have to say for the record 
that the road to hell is paved with good intentions. And you 
folks on this Committee have very good intentions and you're 
wonderful people. But you don't understand--you're not really 
hearing what's being said to you. What's being said to you is, 
you can't regulate algorithms.
    I've been a programmer since I was 13. I can tell you for 
sure, algorithms, especially nowadays, are completely opaque. 
And even if you tried to, they would outprogram you long before 
you got that final vote, long before you got a bill passed.
    Senator Lee. Yes. I don't recall ever having said that we 
should regulate algorithms, nor do I think that's----
    Dr. Epstein. Well, you're talking about----
    Senator Lee [continuing]. Physically possible.
    Dr. Epstein [continuing]. Appointing a special algorithm 
regulator.
    Chair Klobuchar. There was just one question, I think.
    Dr. Epstein. Australia tried regulating algorithms. Your 
concerns here are just not where they should be, in my opinion. 
Instead, you have to look at what you just asked about, which 
is you have to look at where the rubber meets the road. It 
doesn't matter who's programming what. What matters is what the 
consumer is actually getting on his or her computer.
    And all of that is personalized. There's no way to know 
what they're getting unless you are looking over the shoulders 
of a very large number of real users who cannot be identified 
by the tech companies.
    And we've been building that kind of technology since 2016, 
and America's Digital Shield is our attempt now to build a 
permanent, self-sustaining system that looks over the shoulders 
of tens of thousands of Americans in all 50 States, politically 
balanced, representative of each population in each State, and 
court-admissible. And that is what we have been doing.
    And it's very, very difficult. That's a $3 million website 
you were looking at. It's very difficult to find those voters, 
explain to them what we're doing, get them to agree to sign 
NDAs, very rigorous NDAs, and that's what we do.
    Senator Lee. Okay. Can I ask a question about your Youth 
Content Project?
    Dr. Epstein. Yes.
    Senator Lee. It's my understanding that it's shown that 
Google's exposing children to videos on YouTube that are 
inappropriate. In some cases, sexually explicit, or otherwise 
disturbing, harmful in one way or another. How has your 
research uncovered this under the UpNext feature? And how do 
your--how does YouTube use algorithms to select the UpNext 
content shown to children?
    Dr. Epstein. Well, this has already been mentioned by other 
people here, but YouTube selects content to increase watch 
time. And this is true even for 5-year-olds. They want more 
watch time because then the 5-year-old will run to mommy and 
say, ``Mommy, buy that.'' So that's the key here. Watch time 
equals revenue. Period. Leaks from these companies, especially 
Facebook, have shown this unequivocally.
    So, what we are doing now, we have, through our field 
agents, we've gotten--we've been able to connect to our system, 
the mobile devices of more than 2,600 children--children of 
some of our field agents who want to know what content those 
kids are seeing. And this content--if someone would turn the 
screen on, again, it's displaying right now in real time.
    This content is shocking. I've had research staff who will 
not work with this content. They won't do it because it is so 
disturbing. This is going to our kids, and it's going to kids 
in such a way that parents don't even know what's going on.
    [Large viewing screen is displayed.]
    Dr. Epstein. There is no way to understand anything that's 
happening on the internet unless you are looking over the 
shoulders of tens of thousands of real people. They have to be 
real people, real kids, real voters.
    That's why we've been working so hard to build this 
system--and it works. And we have learned ways to analyze the 
data in real time that's streaming in for more than 10,000 
computers, and we're going to get that number up to 40 or 
50,000, if we can.
    Senator Lee. And to be clear, that's content that's 
appearing on a platform designed for kids, marketed to kids, 
marketed to parents as for kids.
    Dr. Epstein. Not only are these images coming from real 
videos being watched by real kids, these are recommended----
    Senator Lee. Right.
    Dr. Epstein [continuing]. These are recommended videos. We 
keep track----
    Senator Lee. For kids----
    Dr. Epstein [continuing]. Of what's----
    Senator Lee [continuing]. Recommended.
    Dr. Epstein [continuing]. Recommended and what they're--
what people are actually watching.
    Senator Lee. Now tell me, if you can, imagine a world in 
which Google did not have monopolistic market power. Just 
imagine that world for a minute--John Lennon's ``Imagine'' is 
playing in the back of your mind. How--how would Google's 
behavior change? How would the experience with Google and 
Google products change?
    Dr. Epstein. I'm not exactly sure what you're asking.
    Senator Lee. So, any of the things that we're talking 
about. Would--would Google ever have been in a position where 
it was telling half the country which side of the political 
aisle it wanted them to gravitate toward? Would it be directing 
content to kids that it shouldn't be?
    Dr. Epstein. If we were monitoring on a large scale and in 
a scientifically validated manner, which is what we've been 
building here, okay, Google would pull out. They still could 
make billions of dollars, but they would pull out. They'd stop 
the manipulations of our elections. They'd stop the 
manipulation of pricing to the extent that they're doing it. 
They would stop because they could still make money, but we 
would be making them accountable.
    What you're seeing on the screen right now are elections 
that Google has flipped. We have a long, long list of elections 
that Google has flipped----
    [Large viewing screen is displayed.]
    Dr. Epstein [continuing]. Because we now know how to 
calculate precisely how many of the votes they're shifting in 
each election because we not only have the basic research, but 
we also now have evidence coming to the eyeballs of real 
voters. We have the evidence showing they're actually showing 
people this content.
    Senator Lee. Thank you. Professor Alford, I want to ask a 
variation of the same question to you. What--what would Google 
look like, or how would it be different than it is today if it 
didn't have monopolistic control? If it didn't have market 
dominance that it does?
    Professor Alford. Yes. Let me just respond to----
    Senator Lee. Yes.
    Professor Alford [continuing]. His comment, if I can, as 
well. He says the road to hell is paved with good intentions, 
but also the road to heaven is paved with good intentions, as 
well, I think.
    And you cannot regulate algorithms, but you can identify 
where the incentives are, and you can address concerns about 
conflicts of interest, and you can create structural relief for 
the largest companies and impose duties of--the best-interest 
duties and things like that on the medium-sized companies.
    So you can do things to address the incentives even if you 
can't regulate the algorithms directly. The answer to your 
question----
    Senator Lee. It's not the algorithm that you're really 
after, it's----
    Professor Alford. It's the incentives.
    Senator Lee [continuing]. Wanting to regulate. Yes.
    Professor Alford Exactly. But to answer your question, if 
there was competition, genuine competition in the marketplace, 
then companies would do the best that they can to increase 
their market share, and address all of their audiences in a way 
that was respectful of them. Right?
    They would--they would engage in behavior that increased 
the chances of them maintaining the audience. Because if the 
audience is upset with you, they'll go somewhere else.
    We know with other markets where there are price 
competition, or quality competition, or viewpoint competition 
that individuals migrate to those other alternatives. Right?
    And so, I think the fact that there's not sufficient 
competition in these marketplaces means that they do what you 
said, which is they abuse their own clients. And they wouldn't 
do that if there was genuine competition.
    Senator Lee. Thank you.
    Chair Klobuchar. Okay. Thank you very much, Senator Lee. I 
guess I'd start out with you, Dr. West, of, sort of, this area 
of what we can do, and no one is serious that we're going to 
lean, we're going to look over at people's algorithms and the 
like, and be in their homes.
    To the opposite. We want to get more privacy regulation and 
control their rights on their data, and we also want to protect 
kids more. There's many upgrades we can make to those laws 
and--but right now we're focused on the competition piece of 
it.
    And Dr. West, one idea that would be helpful, I think, to 
figure out what's going on, is to allow more transparency. We 
are talking about the opaqueness of this. How can increased 
transparency help protect consumers from anticompetitive 
conduct by algorithms? And of course, we had this bill, Senator 
Coons and I, and others about allowing researchers to know 
what's going on. Dr. West.
    Dr. West. Absolutely. I think it's a great question. So, 
for one, given the domains in which algorithmic systems are 
being deployed, it's particularly important that consumers know 
when algorithmic systems have been used in making decisions 
that are shaping their lives, their access to resources, their 
life chances.
    And that's a step toward addressing the significant 
information asymmetries that give dominant firms their power. 
But it's also clear that transparency won't be enough, because 
often these systems are used by those with, you know, greater 
power on those with comparatively less power. You know, think 
about in the workplace, in, you know, real estate, where you're 
applying for housing in a concentrated market.
    There may not be an option to opt out or to seek remedy, 
and that's why complementing transparency mandates with strong 
enforcement of our existing laws and other bright-line measures 
is going to be especially important to protecting both 
consumers and competition.
    Chair Klobuchar. Okay. Very good. And would you like to add 
anything else about other issues that have been raised here?
    Dr. West. I would just concur with Professor Alford that 
you can regulate companies, and we should regulate tech 
companies, in particular.
    Chair Klobuchar. Yes. As you know, we haven't done any--
we've passed things out of this Committee, and Senator Lee and 
I passed the Venue bill, which allows State AGs to do more, and 
we've given some more resources to our enforcers.
    But so far, getting these through the floor in both Houses 
has alluded us in terms of putting some guardrails in place, 
and I think that this--the time is passing here and we have to 
get this done.
    So, I guess I turn to you, Mr. Hewitt. You heard about the 
discussion about what can be done. Could you talk a little bit 
about what Congress can do to get at some of the issues that we 
have raised that you and I talked about with discrimination?
    Mr. Hewitt. Sure. Well, transparency, Senator Klobuchar, is 
certainly part of it. We also need something that frankly could 
trigger an incentive to do the right thing, and that is 
potential liability. That's where----
    Chair Klobuchar. I was--when Senator Lee was, sort of, he 
paused and he said, ``What if Google didn't have,'' and then 
you, you said a monopoly, which is true and a very valid 
question. I thought you were going to say, ``What if they 
didn't have immunity from any lawsuit? ''
    Mr. Hewitt. Well, it's----
    Chair Klobuchar. And that to me is something Senator Graham 
has been pushing for a long time because of the inability of 
the Congress to take any action on any of these things. And 
luckily, we have, again, given the tools or resources to the 
antitrust enforcers to do it.
    But we really don't have any choice, then, because there 
is--unless we just want this to continue where fentanyl-laced 
pills are being sold on these sites--one-third of the people 
that get poisoned with fentanyl get them off the platforms, 
whether we want to just continue with some of the pornography, 
the revenge porn, all these things going on. There's just no 
liability, and they're raking in like a $1 trillion dollars, 
so. Oh, that's how much their value is.
    Mr. Hewitt. That's right.
    Chair Klobuchar. So, I just--at some point, they use some 
of that profit to get the stuff off their sites. It's just 
like--it's pretty much common sense when we regulate everything 
else. But Mr. Hewitt, I didn't mean to interrupt you. But thank 
you for raising the point. Continue.
    Mr. Hewitt. Well, look, I will just--I know we're short on 
time. I will say there's a host of harms. As this Committee 
does its work, I'm also thinking about how this fits into the 
AI Insight Forum, where I saw you a few weeks ago, where we 
focused on the impact of AI on elections and democracy.
    I think about the fact that platforms like YouTube are an 
information super highway for white supremacist content. The 
same content that inspired the shooter in Buffalo who went to a 
Black neighborhood just to kill Black people, that content was 
on YouTube in 2019. We sent a letter asking them to take it 
down from a particular user. But we can't whack every single 
mole.
    And so, you're right that potential liability must be on 
the table for these companies, whether it be in terms of social 
media companies or other companies. And we're not talking about 
lawsuits flying left and right, we're talking about 
incentivizing proper conduct.
    If anyone on this Committee or any of your staff used a 
toaster for breakfast this morning, that toaster is more 
regulated than AI is regulated today. That does not make any 
common sense, and that is a problem that Congress can address.
    Chair Klobuchar. Well said. Mr. Baer, many dominant tech 
companies use algorithms, as we know, to determine what 
consumers are going to see in response to a search query. This 
gives them, as we just talked about with Professor Alford, it 
gives them ability to preference their own products and bury 
those of their competitors.
    That's one of the reasons that Senator Grassley and I and 
others on this Committee introduced the American Innovation and 
Choice Online Act, to set commonsense rules of the road. How 
can this type of self-preferencing by entrenched gatekeepers 
harm competition and deter innovation?
    Mr. Baer. Well, if people are locked in, if companies, the 
platforms have market power, if they are essential to 
communicate with consumers, that gives them the power to 
exclude rivals, to preference their own products, to extract 
rent from people, to get placement on the website that 
disadvantages those who want to compete.
    People have talked about the Amazon complaint by the FTC, 
which I agree is a very thoughtful, plain English description 
of some of these bad behaviors. But this notion that you can 
penalize people that price lower on sites other than Amazon, 
that tends to be a most-favored-nations thing where the rising 
tide inappropriately lifts all boats up to the same price.
    Amazon, too, according to that complaint, can basically 
penalize and does penalize firms that have, find a less 
expensive way of delivering the product to a consumer not using 
Amazon's Prime delivery service.
    As you noted earlier, that a company that is on Amazon, and 
you need to be Amazon because it's a dominant provider, they 
basically get a whole lot less of the price a consumer is 
paying for the product or service they're buying.
    And if you can't offer it for less anywhere else, we have 
this situation that your legislation would address that would 
stop those dominant firms from profiting off their dominant 
position.
    Chair Klobuchar. Thank you. Here's an interesting one, Ms. 
West. So, we've always assumed that these price-fixing cartels 
are likely to form in highly concentrated industries. Right? 
Because they're the ones that they're--they tend to be able to 
say, okay, let's just fix this price, and then there aren't 
other people out there, so we're going to make a lot of money.
    But algorithms actually can expand the number of industries 
in which price fixing can occur. How does the use of algorithms 
and artificial intelligence potentially expand the types of 
industries where price fixing can take place?
    Dr. West. So, as you've noted, historically, we would look 
for cartel-like behavior in markets where there's either a 
small number of players, making it easy for them to coordinate 
with one another, or where all of the key firms are selling the 
same kinds of products. It would be too hard to coordinate 
behavior otherwise.
    But what algorithmic systems do well is they enable firms 
to deal with complexity. So, it enables firms that would 
otherwise have difficulty colluding, to effectively coordinate, 
whether intentionally or not, using large amounts of data 
across differentiated products. And the effect that this has is 
to extend the potential for collusion into places where it 
otherwise would've been near to impossible to execute in 
practice.
    Chair Klobuchar. Dr. Alford, in your testimony, you note 
that algorithms can make price-fixing cartels more stable by 
minimizing the incentives to cheat. Can you talk about how 
algorithms can make price fixing cartels more sustainable?
    Professor Alford. Yes. So, the algorithm price-fixing 
behavior that's possible is essentially where you defer to a 
central decision-maker about how pricing will happen.
    And so, as Dr. West said, you could have literally 
thousands or even millions of individuals that could defer to 
that. And the stability then would be decided because there's 
deference to a central decision-maker that can make that, and 
then there's stabilization that can happen as a result of that. 
So that's one way.
    The other way is what I mentioned earlier very briefly with 
the signaling features where--so, consumers or regulators may 
have a hard time identifying price signaling behavior that is 
happening, but because of algorithms, you can do very, very 
fast signaling to your competitors about pricing behavior. And 
only if you're really knowing what to look for will you even be 
able to see it.
    And so, we see that in the airline industry where there's 
so-called flash information sharing where signaling can happen 
because of the instantaneous nature of it, and they can 
immediately signal and then send back the price so that it 
doesn't even reach the consumer necessarily, but it reaches the 
seller. That's another example of stabilization.
    Chair Klobuchar. Very good. Senator Lee, you have any 
other? Okay, good. This has been actually really helpful for 
all of us because--and I like some of the ideas that you've all 
had, the transparency, looking if there's some changes we need 
to make to the laws that would actually, could be very tailored 
to the price fixing focus.
    We know with AI in general, Mr. Hewitt, that--and with the 
algorithms, that there can be all kinds of discrimination based 
on past information that just is putting you in a place. And 
it's been proven time and time again when people have done 
experiments with it that we cannot be. And so, I think we know 
in that grouping of changes we're going to make, I think 
there's a lot of possibility to be looking at this as well.
    So as hard as this all seems, as my colleagues expressed, I 
actually see some potential for us to move on this on a 
bipartisan basis because of the fact that we're going to be 
doing a bunch of stuff on AI, and this kind of gives us the--
because it's so closely linked. Not the same, but linked.
    It kind of gives us some possibilities to move there or to 
do a separate thing as Senator Lee and I have done successfully 
in the past, some, a special thing, that's focusing on the on 
algorithms and what that means.
    And I just think, just to stand by and think we're not 
going to do anything. My favorite example was your example, Mr. 
Hewitt, about the toaster. And, you know, we do major, major 
deals about dressers that are falling down, which is a legit 
thing that killed kids. Right?
    But these things right now are killing so many kids a day, 
from them getting hooked on drugs or other things that they're 
getting off these platforms. And for us to just do nothing, it 
just would literally be a dereliction of duty.
    So that's why I think we're just starting to see change. 
Certainly, the public is with us, at least a jury of our peers, 
of 12 people were with us on one day, and the cases are moving 
and all of that.
    And my plea, as I do in almost every hearing, is that the 
companies who I know have people out there--they have their 
people, that they--many of them, that they listen, and that 
they think of how we can work on these things to actually put 
some guardrails in place.
    Because otherwise, they're leaving us with no alternative 
but the legal system and lawsuits, and I think there is a 
better way to go here. Okay. Anything else you want to add?
    Senator Lee. No. Thank you for being here. This is a great 
hearing. Learned a lot from you. Thanks.
    Chair Klobuchar. Okay. We are going to keep this record 
open for 1 week, and the hearing is adjourned. Thanks.
