The Global Dominance of European Competition Law Over American Antitrust Law
Working Paper (2019) (with Anu Bradford, Katerina Linos, and Alex Weaver)

The world’s biggest consumer markets—the European Union and the United States—have adopted different approaches to regulating competition. This has not only put the EU and US at odds in high-profile investigations of anticompetitive conduct, but also made them race to spread their regulatory models. Using a novel dataset of competition statutes, we investigate this race to influence the world’s regulatory landscape and find that the EU’s competition laws have been more widely emulated than the US’s competition laws. We then argue that both “push” and “pull” factors explain the appeal of the EU’s competition regime: the EU actively promotes its model through preferential trade agreements and has an administrative template that is easy to emulate. As EU and US regulators offer competing regulatory models in domains as diverse as privacy, finance, and environmental protection, our study sheds light on how global regulatory races are fought and won.


The (Limited) International Influence of the Chicago School of Antitrust Analysis
Working Paper (2019) (with Anu Bradford and Filippo Maria Lancieri)

Beginning in the 1950’s, a group of scholars primarily associated with the University of Chicago began to challenge many of the fundamental tenants of antitrust law. This movement—which became known as the Chicago School of Antitrust Analysis—profoundly altered the course of American antitrust scholarship, regulation, and enforcement. What is not known, however, is the degree to which Chicago School ideas influenced the antitrust regimes of other countries. By leveraging new datasets on antitrust laws and enforcement around the world, we empirically explore whether ideas embraced by the Chicago School diffused internationally. Our analysis illustrates that many ideas explicitly rejected by the Chicago School—like using antitrust law to promote goals beyond efficiency or regulate unilateral conduct—are common features of antitrust regimes in other countries. We also provide suggestive evidence that the influence of the antitrust revolution launched by the Chicago School has been more limited outside of the United States.


Rethinking Law School Tenure Standards
Working Paper (2019) (with Jonathan Masur Kyle Rozema)

Academic departments decide on tenure standards with limited evidence about their accuracy and efficacy. We study the implications of stricter tenure standards in law schools, an environment in which 95 percent of all tenure track hires receive tenure. To do so, we construct a novel dataset of the articles and citation counts of 1,720 law professors who were granted tenure at top-100 law schools between 1970 and 2007. We first show that pre-tenure research records are highly predictive of future academic impact. We then simulate the costs and benefits of applying stricter tenure standards using predictions of law professors' future academic impact at the time of their tenure decision. Of faculty members not tenured under stricter standards, only 5 percent have greater future academic impacts than their counterfactual replacements. Moreover, increasing tenure denials by 10 percentage points would increase the academic impact of a school's median professor by over 50 percent.


Affirmative Action in Law Reviews
Working Paper (2018) (with Jonathan Masur Kyle Rozema)

Policies designed to increase the diversity of law review editors are being challenged in court. The lawsuits claim that, by "illegally us[ing] race and gender as criteria for selecting law students to staff their most elite academic journals," the law reviews have diminished the quality of the articles they publish. We test this claim by using citations as a measure of article quality and studying changes in diversity policies at the flagship law reviews of the top 20 law schools. Using data on the citations of articles published since 1960, we find no evidence that diversity policies meaningfully decrease the quality of articles published.


Political Discrimination in the Law Review Selection Process
Coase-Sandor Working Paper Series in Law and Economics, No. 832 (2018) (with Jonathan Masur Kyle Rozema)

The career trajectories of law professors and the dissemination of knowledge depend on the publication decisions of law review editors. However, these publication decisions are shrouded in mystery, and little is known about the factors that affect them. In this article, we investigate one potentially important factor: political ideology. To do so, we match data on the political ideology of student editors from 15 top law reviews over a 15 year period to data on the political ideology of the authors of accepted articles. We find that editors accept articles in part because of shared political ideology with authors. That is, conservative editors are more likely to accept articles written by conservative authors, and liberal editors are more likely to accept articles written by liberal authors. We then investigate potential explanations for this ideological discrimination. One possibility is that student editors simply have a preference for publishing articles that promote their political ideology. Another possibility is that student editors are objectively better at assessing the contribution of articles written by authors with shared ideology. We find evidence that the ideological discrimination is driven by student editors’ superior ability to ascertain the quality of articles that match their own ideology.
