In theory, partial cross-ownership affects product prices and consumer welfare negatively, but empirical evidence is highly controversial. For competition policy it is important whether such effects are substantial enough to cause action. We report a lab experiment on a homogeneous duopoly...

The common prior assumption is pervasive in game-theoretic models with incomplete information. This paper investigates experimentally the importance of inducing a common prior in a two-person signaling game. For a specific probability distribution of the sender's type, the long-run behavior...
