Megafusionen werfen viele Fragen auf: Handelt es sich um die rationale Antwort auf Globalisierung und deregulierte Märkte? Oder entspringen solche Zusammenschlüsse eher dem Machtwillen eines 'größenwahnsinnigen' Managements? Und welche wettbewerbspolitischen Konsequenzen haben diese...

The authors provide evidence on the impact of foreign ownership on labor market outcomes analyzing pay differences between foreign-acquired and domestically owned firms. For this purpose, they use firm-level data from 16 European countries over the time period 19992006. Combing propensity score...

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 mergerrelated exits. Within...

We analyze the efficiency defense in merger control. First, we show that the relationship between exogenous efficiency gains and social welfare can be non-monotone. Second, we consider both endogenous mergers and endogenous efficiencies and find that merger proposals are largely aligned with a...

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 analyze a Bayesian merger game under two-sided asymmetric information about firm types. We show that the standard prediction of the lemons market model-if any, only low-type firms are traded-is likely to be misleading: Merger returns, i.e. the difference between pre- and post-merger profits,...

This paper investigates the merger wave hypothesis for the US and the UK employing a Markov regime switching model. Using quarterly data covering the last thirty years, for the US, we identify the beginning of a merger wave in the mid 1990s but not the much-discussed 1980s merger wave. We argue...
