Madan Dhanora, Mohd Shadab Danish, and Ruchi Sharma review the history of the Indian government’s efforts to encourage innovation, how these efforts have manifested in the national pharmaceutical industry, and what steps the government can take to further improve innovation.

Steven C. Salop evaluates the final version of the 2023 Merger Guidelines on vertical merger analysis and certain rebuttal arguments. He finds that the final Guidelines successfully incorporate developments in the economic scholarship and update antitrust enforcement with the tools to analyze non-horizontal mergers in an increasingly digital economy.

The Department of Justice Antitrust Division and Federal Trade Commission released their completed version of the new 2023 Merger Guidelines. Susan Athey, Chief Economist for the DOJ Antitrust Division, and Aviv Nevo, Director of the FTC’s Bureau of Economics, explain how the revised document addresses the comments they received on the Draft Merger Guidelines that were expressed in ProMarket and elsewhere.

Recent antitrust interventions have put forward behaviorally informed theories of harm. However, they have adopted a deterministic model of behavior, missing the nuances that allow behavioral economics to provide a richer picture of people’s conduct. The recently concluded Google trial, grounded on the stickiness of defaults, is a good example. A more careful application of behavioral economics would have shown how Google’s purchase of default search engine status was a part of a broader monopolization plan. It would also show why the dominant remedy, forced choice, would have negligible effects.

Steven C. Salop analyzes the Fifth Circuit Court’s opinion accepting the Federal Trade Commission’s suit to block Illumina’s acquisition of Grail. The ruling sheds light on how courts may approach vertical merger analysis and “litigating the fix” in the future, and what this may mean for the Merger Guidelines’ approach to vertical mergers.

The final version of the Agencies’ Merger Guidelines are a thoughtful improvement over the draft version, writes Fiona Scott Morton. Both the economic and legal analysis in the final version promise to more effectively prevent harmful mergers and bring U.S. antitrust into the modern age.

In new research, Seong Jin Ahn, Jared N. Jennings, and Yanrong Jia find that SEC enforcement against insider trading does not deter subsequent insider trading so much as displace it to other actors in the same industry.
