Why has antitrust enforcement declined in the United States since the 1970s? Is it due to the preferences of voters or business influence? In this symposium, Jonathan Baker, Eleanor Fox, and Herbert Hovenkamp will discuss the findings of Eric Posner, Luigi Zingales and Filippo Lancieri’s new paper, “The Political Economy of the Decline of Antitrust Enforcement in the United States.” Lancieri summarizes the findings of the paper here.

Hamid Mehran discusses proposals for reforming bankers' compensation to better align incentives and risk-taking. Mehran contends market-based, self-regulating compensation structures would enhance governance and financial stability more effectively than punitive bonus caps or clawbacks imposed by regulators.

In new research, Taylor Begley, Peter Haslag, and Daniel Weagley find that when firms begin sharing a common director, there is a significant reduction in the number of employees that switch jobs between the two companies. The reduction is largest when the firms compete in the same labor market and for those employees who are most costly for firms to replace. The results show the link between overlapping board members and anticompetitive labor practices is a surprisingly widespread phenomenon.

Four economists discuss the trends in the global economy they are tracking in 2024

Politicians often interfere with central banks, but it is not clear how to measure such political pressure systematically and therefore difficult to quantify its economic consequences. In new research, Thomas Drechsel finds that political pressure strongly and persistently raises inflation and inflation expectations but has little impact on economic activity.

Hao Zhang examines how global value chain partnerships among large, monopolistic firms in the US enable new forms of political coordination and coalition-building to influence trade policy in their favor, despite popular backlash against globalization.

In new research, Giovanna Massarotto explains how collusion manifests differently in the digital economy. She argues that antitrust regulators, scholars, and courts need to incorporate lessons from computer science to update how they monitor markets and identify algorithmic collusion.

In new research, Alma Cohen finds that the political affiliations of Circuit Court judges influence decisions in a much wider variety of cases than previously thought.

Stricter merger policy guidelines will increase competition, leading to higher wages and welfare for workers, writes Kyle Herkenhoff and Simon Mongey. The authors use economic modeling to show that the stricter 2023 Guidelines will improve worker welfare, and that even tighter thresholds can be applied to labor markets to amplify worker welfare gains from antitrust policy.
