Gründungen durch Akademiker finden häufig erst Jahre nach dem Ausscheiden der Wissenschaftler oder Absolventen aus der Universität statt. Diese akademischen Unternehmensgründungen stellen einen wichtigen Transfermechanismus der wirtschaftlichen Verwertung von Forschungsergebnissen und...

Nur sehr wenige junge Unternehmen nutzen eine Finanzierung durch externe Investoren, eine so genannte Beteiligungsfinanzierung. Zum einen sind die meisten Unternehmen nicht attraktiv für Investoren, zum anderen scheuen Unternehmensgründer die Mitsprache durch Dritte. Einen leichteren Zugang zu...

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 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...

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 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 use publicly available price data from the German cement industry to estimate the cartelinduced price increase. We apply two different comparator-based approaches - the 'before and-after' approach and the 'difference-in-differences' approach - and especially study the impact of various...

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...
