Do merger reviews promote competition and stall consolidation?

Grant description:

This project will provide estimates of the impact of prospective merger reviews on antitrust enforcement actions, product prices, input prices, output, investment, and research and development. Using administrative data collected through taxation, employment, and antitrust provision, the project exploits the introduction of a premerger notification policy in Chile to see how it changed the types of mergers being agreed to.

The result will help policymakers understand how much notification systems have a deterrent impact. Prospective merger reviews constitute a large share of antitrust enforcement expenditures, and yet little work has systematically studied its effectiveness. By providing a comprehensive study across industries using detailed data on real economic variables, this project could provide invaluable insights into the effects of mergers in both input and output markets, the impact of notification requirements, and the resource allocation within enforcement agencies.
