Eric Posner discusses why many antitrust professionals believe the law follows economic interpretation, despite the absence of economics in the relevant statutes. He argues that antitrust laws themselves have been resistant to adopting a coherent "economic theory" approach, leading to a tension between the economic views of agencies and academics versus the legal interpretations taken by courts.

Similar to noncompete clauses in employment contracts, training repayment agreements, which require employees to pay back their employers for firm-sponsored training if they quit early, can impede worker mobility and reduce competition in labor markets. The authors document the pervasiveness and characteristics of these provisions and suggest directions for future research.

The European Commission has fined Apple for abusing its App Store. The Commission did not mention Spotify, but the fine appears to answer the music streaming platform’s complaint that Apple’s App Store fees to developers are too high. But now that Spotify has seen Apple’s new approach under Europe’s new Digital Markets Act, Spotify is still unhappy, highlighting the flaws of Spotify’s original complaint and the Commission’s fine, writes Randy Picker.

The 2023 banking crisis that took down four banks, including Silicon Valley Bank, by all appearances appears to have been resolved by public intervention. Yet, Viral Acharya and Raghuram Rajan argue, this leaves many of the underlying weaknesses that contributed to the bank failures unaddressed. Moreover, while the authorities’ temporary fixes have stopped the panic, the system will have to absorb more unrecognized losses over time.

Elon Musk recently sued OpenAI over claims that the company has strayed from its social mission and has instead focused on profit maximization. Roberto Tallarita examines how Musk’s lawsuit shows well-intentioned corporate planners how hard it is to commit to an effective and enforceable social purpose and warns policymakers that relying on corporate self-regulation of AI could be a fatal mistake.

Nearly one in five American workers are affected by noncompete agreements, which prevent workers from working for or creating a rival firm. In new research, Axel Gottfries and Gregor Jarosch estimate that the Federal Trade Commission’s proposed noncompete ban could raise wages by 4%.

The various antitrust complaints the Department of Justice and the Federal Trade Commission have brought against Google, Amazon, and Facebook are based on monopolization claims under Section 2 of the Sherman Act. Herbert Hovenkamp explains why the government should also  have relied on Section 1 of the Sherman Act and Section 7 of the Clayton Act to support their Big Tech cases.

From the Kennedy family to Chile's Matte family, powerful and wealthy families often seek political office. New research by Patricio Duran, Marcelo Ortiz, and Michael Carney seek to understand what those politically active families have in common and discuss potential motivations.

Neoclassical economics, which places the rational and well-informed actor maximizing utility at its foundation, underpins the dominant schools of thought on firm behavior in antitrust. Although neoclassical economics assumes that firms maximize profit, it has little to say on the actual decision-making processes within firms that drive firm conduct. In part, this is because neoclassical economists view the firm as a “black box,” whose decision-making behavior is too idiosyncratic or obscure to link to output and performance. At the same time, neoclassical assumptions about firm rationality and profit maximization mean that whatever these idiosyncratic behaviors of the individual firm may be, they are designed to maximize profit and returns to owners. Thus, firm decisions can be presumed to be rational.
