Do horizontal mergers induce entry? Evidence from the US airline industry

International audience; 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 empirically. Our results show that both entry-inducing and entry-dissuading effects can be observed depending on the type of affected route and the carrier under investigation.
