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...

We use T-100 traffic data and DB1B fare data from the U.S. Department of Transportation to identify patterns and effects of entry by network carriers and low-cost carriers in non-stop U.S. airline markets. For the sample period from 1996 to 2009, we find that entry activity of low-cost carriers...

We study the competitive effects of five liquidations and six mergers in the domestic U.S. airline industry between 1995 and 2010. Applying fixed effects regression models, we find that route exits due to liquidation lead to substantially larger price increases than merger-related exits. Within...

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 study the price effects of mergers in airline networks. Guided by a review of the existing theoretical and empirical literature, we develop two classifications of routes possibly affected by an airline merger. Subsequently, we apply a difference-in-differences approach to exemplarily...

For academic spin-offs I analyze the length of the time period between the founder's leaving of academia and the establishment of her firm. A duration analysis reveals that a longer time-lag is caused by the necessity of assembling complementary skills, either by acquisition by a single founder...
