The paper develops a four-step framework to detect anticompetitive horizontal mergers. In the first step, an estimate of the impact of the merger on the market price needs to be derived. Subsequent, the second step of the framework has to assess whether such a predicted price increase would be...

The article studies the evolution of the domestic U.S. airline industry from 1995 to 2009 using T-100 traffic data and DB1B fare data from the U.S. Department of Transportation. Unlike previous studies, a consistent split of the analysis in network carriers and low cost carriers is introduced....

The paper discusses selected antitrust implications of airline alliances. In addition to a categorization of airline alliances and a brief discussion of their key competitive effects, our focus is on an assessment of efficiencies triggered by various degrees of airline cooperation. We find that...

We study the consumer welfare effects of mergers in airline networks. Based on the development of a general classification of affected routes, we apply a difference-in-differences approach to exemplarily investigate the price effects of the America West Airlines-US Airways merger completed in...

Die neue Bundesregierung steht in der kommenden Legislaturperiode vor großen wirtschaftspolitischen Herausforderungen. Zwar war die deutsche Wirtschaftsentwicklung in den letzten Jahren überraschend positiv. Hervorzuheben sind vor allem die starke Zunahme der Beschäftigung und die schnelle...

We use a unique private data set of about 340,000 invoice positions from 36 smaller and larger customers of German cement producers to study the value of such transaction data for an estimation of cartel damages. In particular, we investigate, first, how structural break analysis can be used to...

Public and private action against cartels is an internationally recognized cornerstone of antitrust enforcement. Effective private enforcement requires that cartel victims can receive (at least) full compensation for the harm suffered. Academics and competition authorities support this goal with...

The paper estimates the effects of entry by low-cost carrier JetBlue Airways in long-haul domestic U.S. airline markets. For the period from 2000 to 2009, we find that non-stop fares were on average about 21 percent lower post-entry; however, the magnitude of the price effect depends on the...
