Effective European Antitrust: Does EC Merger Policy Generate Deterrence?

We estimate the deterrence effects of European Commission (EC) merger policy instruments over the 1990–2009 period. Our empirical results suggest phase-1 remedies uniquely generate robust deterrence as—unlike phase-1 withdrawals, phase-2 remedies, and preventions—phase-1 remedies lead to fewer merger notifications in subsequent years. Furthermore, the deterrence effects of phase-1 remedies work best ...

Correcting for Self-Selection Based Endogeneity in Management Research: Review, Recommendations and Simulations

Foundational to management is the idea that organizational decisions are a function of expected outcomes; hence, the customary empirical approach to employ multivariate techniques that regress performance outcome variables on discrete measures of organizational choices (e.g., investments, trainings, strategies and other managerial decision variables) potentially suffer from self-selection based endogeneity ...

Ex Post Merger Evaluation in the U.K. Retail Market for Books

This paper evaluates the price effects of the merger of two major U.K. book retailers. We use a dataset containing monthly scanner data on a sample of 200 books in 50 local markets for four years around the merger. We compare the price changes after the merger in shops located in areas where both chains were present before the merger and in areas where only one chain was present. We also investigate ...

The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

We investigate the welfare impact of parallel imports using a large panel dataset containing monthly information on sales, ex-factory prices, and further product characteristics for all 649 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand, and on the basis of an oligopolistic model of multi-product firms, we then recover the marginal costs ...

A Retrospective Merger Analysis in the U.K. Videogame Market

We study the effect of a merger in a dynamic high-technology industry—the videogame market—which is characterized by the frequent introduction of new products. To assess the impact of the merger between two large specialist retailers in the United Kingdom—Game Group PLC and Games Station Limited—we perform a difference-in-differences analysis comparing the price evolution of the merging parties with ...

Collusion through Joint R&D: An Empirical Assessment

This paper tests whether upstream R&D cooperation leads to downstream collusion. We show that a sufficient condition for identifying collusive behavior is a decline in the market share of RJV-participating firms. Using information from the U.S. National Cooperation Research Act, we estimate a market share equation correcting for the endogeneity of RJV participation and R&D expenditures. We find robust ...

An Empirical Assessment of the 2004 EU Merger Policy Reform

We evaluate the economic impact of the change in European merger legislation in 2004 and propose a general framework focusing on four different policy dimensions: predictability, decision errors, reversion of anti-competitive rents and deterrence. We find that after the reform, the predictability and the accuracy of decisions have improved. Yet, the policy shift away from prohibitions, which entail ...

Competition Policy and Productivity Growth: An Empirical Assessment

This paper estimates the impact of competition policy on total factor productivity (TFP) growth for 22 industries in 12 OECD countries over 1995-2005. We find a positive and significanteffect of competition policy as measured by newly created indexes. We provide results based on instrumental variables estimators and heterogeneous effects to support the causal nature of the established link. The effect ...
