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...

We investigate the impact of cartel breakdowns on merger activity. Merging information on cartel cases decided by the European Commission (EC) between 2000 and 2011 with a detailed data set of worldwide merger activity, we find that, first, the average number of all merger transactions increase...

We investigate the competitive effects of the merger between Delta Air Lines and Northwest Airlines (2009) in the domestic U.S. airline industry. Applying fixed effects regression models we find that the transaction led to short term price increases of about 11 percent on overlapping routes and...

We examine the issue of market foreclosure by airline partnerships with antitrust immunity. Overlapping data on frequency of service and passenger volumes on non-stop transatlantic routes with information on the dynamics of airline partnerships, we find evidence consistent with the airlines...
