The European Union and its member states are quickly updating merger rules to address killer acquisitions and the economics of digital platforms. In a new article published in the Antitrust Law Journal, Anna Tzanaki explores how these endeavors challenge the institutional design of EU merger control and how this design can evolve to tackle new economic and geopolitical problems without forfeiting founding legal principles.

Trade wars between the United States and Canada have sharply reduced the number of Canadian tourists traveling to the U.S. In new research, André Kurmann, Étienne Lalé, and Julien Martin use novel methods to measure how this decline in tourism has negatively impacted American workers and communities.

Firms may file a strategic lawsuit against public participation (SLAPP) against civil society to silence criticism for socially harmful activity, such as the use of dirty technologies.

In new research, Luis Armona and Adam Rosenberg argue that current state firearm excise taxes inadequately address gun-related crimes.

In a recent article, Kate M. Conlow explores how feeble requirements among the American academic economics community to disclose conflicts of interest are compromising research and harming policymaking.

In new research, Eric Dunaway, Ana Espinola-Arredondo, and Felix Munoz-Garcia examine the Herfindahl-Hirschman Index (HHI) as a tool for merger review and show where it diverges from the consumer-surplus and total-welfare standards. In particular, the HHI fails to account for potential efficiency gains.

In new research, Janka Deli analyzes the relationship between the decline in the rule of law and trade. Contrary to democratic and developmental theory, she finds that declines in the rule of law, as seen in Hungary, Poland, and Czechia, do not lead to systematic reductions in trade with other EU partners.
