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...

In recent years, reverse patent settlement agreements — whereby a patent holder pays or gives other forms of value to an infringer in order to avoid or to settle patent litigation — have raised considerable debate in the pharmaceutical field in both the United States and the European Union,...

By reference to case-law and soft law in three jurisdictions (Canada, US and EU), this paper explores how courts and agencies carry out balancing exercises in the application of competition law. The paper identifies three approaches: utilitarian balancing, consumer welfare balancing, and...
