We analyze the effects of downstream firms' acquisition of pure cash flow rights in an efficient upstream supplier when all firms compete in prices. With an acquisition, downstream firms internalize the effects of their actions on their rivals' sales. Double marginalization is enhanced. Whereas...

Due to potential abuse of the market power at wholesale and retail market level for natural gas the Federal Cartel Office in Germany prohibited further forward integration of gas importing firms with retail incumbents from 2005/2006 to 2010. The Authority argued that the very few dominant gas...

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 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 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-indifferences approach to exemplarily investigate the price effects of the America West Airlines - US Airways merger completed in...

Theoretical research has investigated the relevance of entry-inducing effects as countervailing factor to a merger-related increase in market power. We use route-level data for the America West Airlines - US Airways merger (2005) to investigate whether such an effect can be identified...

We investigate the relationship between public and private enforcers introducing a more differentiated approach. In contrast to the existing literature, we take into account that the costs and benefits of detection and prosecution and, thus, the usefulness of each enforcement mode may change...

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 paper aims at assessing the costs and benefits of antitrust enforcement. The analysis starts with an investigation of why competition is typically worth protecting followed by a collection of empirical evidence which shows that competition actually needs protection by antitrust policy in...

Im Jahre 2005 fand im Rahmen eines OECD Policy Roundtables ein intensiver Meinungsaustausch der Mitgliedsstaaten zu dem Thema 'Evaluation of the Actions and Resources of the Competition Authorities' statt. Eine wesentliche Erkenntnis der Gespräche bestand in der Feststellung, dass...
