    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 ...

    The Effect of Retail Mergers on Prices and Variety: An Ex-post Evaluation

    Unlike most retrospective merger studies that only focus on price effects, we also estimate the impact of a merger on product variety. We use an original dataset on Dutch supermarkets to assess the effect of a merger that was conditionally approved by the Dutch Competition Authority (ACM) on prices and the depth of assortment. We find that the merger did not affect prices but it led the merging parties ...
