#365 What Roles Do Economists Play in Chinese Competition Law? Conversation With Dr. Vanessa Zhang

Five years after the Supreme Court's AMG Capital Management decision limited the FTC's ability to seek monetary remedies under Section 13(b) of the Federal Trade Commission Act, the agency continues to look for ways to obtain money in consumer protection and privacy cases through other authorities and theories. At the same time, it is grappling with how to define and measure consumer injuries and benefits in an increasingly data driven economy, including through its February 26 workshop on "Consumer Injuries and Benefits in the Data Driven Economy." Hosts Lexi Michaud and Anora Wang talk with Laura Riposo VanDruff from Kelley Drye and Warren LLP and Mike LeGower from NERA about how the FTC is pursuing monetary relief after AMG, whether and how it might articulate clearer guidance for quantifying harm, and what companies should expect when facing privacy and data investigations by the FTC.

In February 2025, new rules for the pre-merger notification requirements in the U.S. came into effect. But will a February 2026 court decision undo these changes? Daniel Rosenthal, partner at Kirkland & Ellis, joins Jaclyn Phillips and Lexi Michaud to discuss a decision vacating the new rules, the subsequent appeal, and what might happen next. Listen to this episode to learn more about how to navigate merger filings in an uncertain time. (Since this episode was recorded, the Fifth Circuit denied the FTC's motion to stay the decision vacating the new HSR Rules.  On March 19, 2026, the Premerger Office announced that the Commission is now accepting HSR filings using the Form and Instructions that were in place before the February 10, 2025, effective date of the new rule.  As always, continue to follow the case and consult a lawyer for any legal advice.)

What goes into states' analyses and decisions to intervene? Anthony Mariano, Chief of the Antitrust Division at the Massachusetts Office of the Attorney General, speaks with Lexi Michaud and Anora Wang about how states approach merger enforcement in parallel with the DOJ and FTC, the importance of independent state scrutiny, and, using the HPE–Juniper transaction to guide the discussion, how the Tunney Act promotes transparency and public interest oversight of federal settlements.

In 2006, various parties came together to form Brazil's Amazon Soy Moratorium in an effort to curb illegal deforestation in the Amazon Rainforest. Today, challenges regarding Brazil's Soy Moratorium continue to mount, with passionate advocacy from farmers, environmentalists, government agencies, and international organizations. What might seem a cut-and-dry conflict between free enterprise and environmental conservation becomes more complicated when we delve deeper. With an antitrust cartel investigation in limbo, a pseudo-private agreement to arguably higher deforestation standards than those instituted by the government, and international observers on the scene, including customers and climate activists, the facts surrounding Brazil's Soy Moratorium are ripe for unpacking. Our guest today is antitrust attorney Eduardo Frade, who joins Barry Nigro and Anora Wang to discuss Brazil's Soy Moratorium and the various antitrust and competition questions it raises.
