We experimentally study price-quantity competitions in duopoly and triopoly markets and compare the results with the respective mixed strategy equilibria. The equilibrium does not predict experimental outcomes adequately, but we find indications for a reactive strategy in the experiments.

Positive effects of multimarket activities on cooperation between firms are widely acknowledged. We study these effects in a setting with home market asymmetries as is typical for global competition. In our multimarket duopoly experiment each firm has a home market but may also enter the other...

In online auction platforms, offers are listed side by side and may end at the same point in time. While theoretical studies predict efficient coordination across auctions, experimental and empirical studies observe efficiency losses, i.e. goods remain unsold. In order to mitigate this...
