Antitrust and competition in an internet economy: conference at the Stigler Center

Here's where I'll be today (unfortunately only for the first day of a two day conference), speaking about promoting/preserving competition in matching markets:

2018 ANTITRUST AND COMPETITION CONFERENCE - DIGITAL PLATFORMS AND CONCENTRATION

APRIL 19–20, 2018
GLEACHER CENTER, 450 N CITYFRONT PLAZA DRIVE


About the Conference
The economic and societal role of the handful of large companies known as “digital platforms" has grown dramatically in the last decade. Google, Amazon, and Facebook are not only transforming communication, media, and retail but have the potential to transform many other industries. While they invest billions in research and development and propel important innovation, they also raise many policy questions with regard to their dominance in many markets, the vast consumer data they collect and own, and their influence on the markets for news, information, and ideas. On April 19 and 20, 2018, the Stigler Center at the University of Chicago Booth School of Business will dedicate its annual Antitrust and Competition conference to the topic of “Digital Platforms and Concentration.”
Issues to be discussed at the conference include, among others:
  • The characteristics and market power of two-sided markets 
  • How competition can be promoted in a world of network effects 
  • The economics of free products and the challenges they pose to antitrust and existing law 
  • The collection, monetization, and ownership of personal data 
  • Digital companies’ foray into the physical world
  • How and to what degree digital companies are involved in political decision making
  • How the startup ecosystem is affected by the presence of big players 
The invitation-only conference will bring together approximately 50 economists, law scholars, intellectuals, venture capitalists, and business people for two days of discussion. The keynote speakers will be Makan Delrahim, assistant attorney general of the Department of Justice’s Antitrust Division, Alvin Roth, the 2012 Nobel laureate in economics, and Jean Tirole, the 2014 Nobel laureate in economics.
The conference will be by invitation only. Individuals interested in receiving an invitation, please submit your invitation request here.

The Rise of Digital Platforms
The economic and societal role of digital platforms has grown dramatically in the last decade. Are the large Internet companies really “platforms”? Can they have outsized influence in many market and industries? What explains the size and success of these companies? Are they designing their products to be addictive? What are the most important policy questions that these companies raise?

Big Data: Economic, Ownership, Legal, and Political Aspects
User data is arguably digital platforms’ most valuable asset. How data are used has profound economic, social, and political implications. What are these implications? Where along the value chain do data belong? Could reassigning ownership of the data and making it easily available to users promote competition and address privacy concerns?

The Big Five and Political Power
The largest technology companies—Google, Facebook, Amazon, Microsoft, Apple—are active political players, using the traditional levers of lobbying and financing of research, think tanks, and political campaigns. However, it is their market power, and leverage over media outlets, that opens up new avenues for these platforms and foreign actors that exploit vulnerabilities in their systems to dominate and control the flow of political information among voters. How do they influence political discourse, the marketplace of ideas, and democracy more broadly?

Digital Platforms: Market Power and Market Failures Digital platforms (e.g. Facebook, Google, Twitter) rely on network effects to build vast ecosystems of users, advertisers and third-party developers, and to attain substantive market power. How should that market power be measured and what concerns does it raise for competition and entry? What are the market failures left unaddressed by these digital platforms and how should we expect them to govern their respective ecosystems?

The Amazon Phenomenon
Amazon has transformed e-commerce and now begins its foray into the physical world with its acquisition of Whole Foods. The giant e-tailer offers a quintessential case study in how digital platforms are reimagining traditional markets and impacting society at large. Who will be “Amazoned” next? What lessons can we learn from Amazon’s experience with antitrust? As Amazon looks to situate its second headquarters, some believe the bid is a race to the bottom. What is the anticipated net impact of hosting the headquarters on a winner city and state?

Frontiers of Market Design at Cornell (joint with EC), June 22


Frontiers of Market Design

The first Frontiers of Market Design workshop will be held in Cornell University, Ithaca, NY on June 22, 2018 in conjunction with the 19th ACM Conference on Economics and Computation (EC).
Market design is a field of applied and theoretical research that sits comfortably on the intersection of economics and computer science. In recent decades, the theory and applications of market design have blossomed. In this workshop, we will focus on a set of promising, new applications of market design. In particular, we are interested in applications of market design which involve complex allocation constraints, vast datasets, and dynamic pricing issues. We also want to explore problems which, despite receiving ample theoretical attention, have not been implemented in practice. We welcome theoretical and empirical papers that deal with new domains of market design as well as papers that discuss practical aspects of market design.

Market design as a growing part of computer science

I'm encouraged to see this from Northwestern CS:
SPECIAL QUARTER: DATA SCIENCE & ONLINE MARKETS - APRIL 15 TO JUNE 15

"In recent years many aspects of social engagement has shifted to what can be broadly thought of as online markets. These markets; which include eBay, Uber, Airbnb, Tinder, StubHub, Wikipedia, Amazon’s Mechanical Turk, etc.; are run by technology companies and are built by teams of software engineers. The science of designing and optimizing these online markets, however, is underdeveloped.  Designing a marketplace that works well is challenging because the behavior of participants in the market place depends on the design of the marketplace. ..."

Safe exchange zones

Marketplaces aren't just tools to bring potential transactors together, they can also seek to make transactions (physically) safe.  Criminals can lurk among Craigslist buyers and sellers, and so there's been a growth of "safe exchange zones".


See e.g. this recent story from New Jersey, where the police department set up a safe exchange zone following a robbery/murder:
"Passaic Mayor Hector Lora says that his town installed the zones inside and outside of the police station after a series of robberies and scams related to online sales.

“The biggest difference that it makes is that it provides a safe area for individuals to make these transactions and be able to make it back home,” Lora says.

“We have 24 hour surveillance, 24 hour staffing, and it's round the clock,” says Deputy Chief Christopher Storzillo.

"Lora says that he hopes that other towns follow suit and add their own safe exchange zones.

"But until other towns have these zones, officials urge anyone who is buying or selling items online to meet in a public, well-lit place and to call authorities if anything seems suspicious."

It turns out that safe exchange zones are a thing, here are some databases to help locate one near you:

More Backpage (.com) news


From the Washington Post:
Backpage CEO Carl Ferrer pleads guilty in three states, agrees to testify against other website officials
"Carl Ferrer, the chief executive of Backpage.com whose name was conspicuously absent from an indictment of seven other Backpage officials unsealed Monday, has pleaded guilty in state courts in California and Texas and federal court in Arizona to charges of money laundering and conspiracy to facilitate prostitution. In addition, he agreed to testify against the men who co-founded Backpage with him, Michael Lacey and James Larkin, who remained in jail Thursday in Arizona on facilitating prostitution charges.
Backpage, in addition to hosting thinly veiled ads for prostitution since 2004, was accused of hosting child sex trafficking ads on its site and even assisting advertisers in wording their copy so they didn’t overtly declare that sex was for sale, federal investigators allege. In a remarkable three-paragraph admission in his federal plea agreement, Ferrer wrote that “I conspired with other Backpage principals … to find ways to knowingly facilitate the state-law prostitution crimes being committed by Backpage’s customers.
...
"Ferrer’s sudden capitulation launched a wild seven days for Backpage. A day after Ferrer’s first secret plea, the federal government arrested seven of Ferrer’s former colleagues, including Lacey and Larkin, and shut down Backpage’s websites in the U.S. and around the world. ...
"Then on Wednesday, President Trump signed into law “FOSTA,” the Fight Online Sex Trafficking Act, a bill inspired by the stories of children being prostituted on Backpage..."
**********************
And here's a story from Quartz that follows the work of economists researching the (not all bad) effects of internet marketplaces for prostitution.

Are financial markets too fast? A discussion of high speed trading (with Eric Budish)




"On this episode of The Big Question, Chicago Booth Review's Hal Weitzman talks with Chicago Booth professor of economics Eric Budish, Chicago Trading Company's Steve Crutchfield, and former Commodity Futures Trading Commission commissioner Sharon Bowen about how speed affects financial markets and what, if anything, we should do about it."

Eric points out that competition among exchanges has worked well in driving down trading fees, and poorly in selling access--"co-location"--since each exchange has a monopoly on selling speedy access to its data.

Re-transplanting an organ that survives its recipient

From UCLA (where Dr. Jeff Veale is innovating):
‘Re-gifting’ of previously transplanted kidneys extends life for new recipients
Approach could help people who might not otherwise receive a transplant

"Typically, previously transplanted kidneys are lost to future use when the first recipient dies. But Dr. Jeffrey Veale, a transplant surgeon at Ronald Reagan UCLA Medical Center who has performed the rare surgery three times, maintains that re-donating previously transplanted kidneys should become standard practice.
...
"Veale sums up the re-gift this way: One kidney helped three people live.

“In the United States about 25 percent of those who receive a donated kidney die while their kidney transplant is still functional,” said Veale, director of the UCLA Kidney Exchange Program. “Re-gifting that viable organ to another patient on the waiting list gives new hope to patients who otherwise may not be considered for a transplant.”

With a re-gifted kidney, people who had been reliant on dialysis for years could live normal lives, spending time with their loved ones, traveling or doing anything else that people who aren’t on dialysis may take for granted.

Each year in the U.S., less than 20 percent of patients on the United Network for Organ Sharing kidney transplant waiting list will receive a transplant, and 13 people on that list die each day. If transplanting kidneys a second time were standard practice, it would open up a currently unutilized pool of donors."

Backpage.com, seized by the FBI and indicted by the Department of Justice

The latest development in the legal battle of Backpage.com, an online marketplace for sex and, apparently, trafficking in women and children, has resulted in the closing of the site.

On April 6 2018 the content of the site was replaced with a notice beginning “backpage.com and affiliated websites have been seized as part of an enforcement action by the Federal Bureau of Investigation, the U.S. Postal Service Inspection Service, and the Internal Revenue Service Criminal Investigation Division, with analytical assistance from the Joint Regional Intelligence Center.” 
The accompanying indictment (https://www.justice.gov/file/1050276/download )suggests that the proprietors of Backpage.com may have helped write the site’s content, and thus not be protected by the 1996 Communications Decency Act. 

In a parallel development, in March (of 2018) the Senate passed (by a vote of 97 to 2) and forwarded to the President for signature the Fight Online Sex Trafficking Act of 2017, as previously passed by the House of Representatives. It amends the Communications Act of 1934, “to  clarify  that  section  230  of  such  Act  does  not  prohibit  the  enforcement  against providers and users of interactive computer services of Federal and State criminal and civil law relating to sexual exploitation of  children  or  sex  trafficking…” https://www.congress.gov/115/crpt/hrpt572/CRPT-115hrpt572-pt1.pdf .
