We collect a sample of EU and US in-depth merger investigation, estimate models of the regulatory decisions and use the models to compare merger policies in the two jurisdictions. The approach used allows us to decompose observed differences between merger decisions into regime effects and...

We estimate the deterrence effects of U.S. merger policy instruments with respect to the composition and frequency of future merger notifications. Data from the Annual Reports by the U.S. DOJ and FTC allow industry based measures over the 1986-1999 period of the conditional probabilities for...

Developed economies have historically been a model for emerging market economies, particularly in the development and enforcement of competition laws. Modifications to competition law rules in developed economies, however, may not always be practical for emerging market economies to adopt....

I present the following proposal: information revealed during non-cartel investigations by competition law enforcement authorities, such as evaluation of M&As or investigation of monopolization (dominance) conduct, should be directly used to investigate and prosecute cartels. Currently, in...

The institutional design of federal merger review in the United States leads to systematic underenforcement of merger law. This is so even though substantive merger law is relatively well settled, most mergers are not anticompetitive, and the review process properly permits them to proceed...

We estimate the deterrence effects of U.S. merger policy instruments with respect to the composition and frequency of future merger notifications. Data from the Annual Reports by the U.S. Department of Justice and Federal Trade Commission allow industry-based measures over the 1986-1999 period...

The objective of this paper is to discuss and compare the role that different constituencies play in US and EU procedures for merger control. We describe the main constituencies (both internal and external) involved in merger control in both jurisdictions and discuss how a typical merger case...
