We analyze the Spence education game in experimental markets. We compare a signaling and a screening variant, and we analyze the effect of increasing the number of employers from two to three. In all treatments, there is a strong tendency to separate. More efficient workers invest more often and...

In a framework with an upstream monopoly and a downstream duopoly, we analyze the impact of convex costs on the downstream level. In contrast to the case of constant marginal costs, vertical integration does not imply complete market foreclosure. While the non-integrated downstream firm receives...

The recent literature on vertical foreclosure suggests that vertical integration can have the anticompetitive effect of enabling an upstream firm to commit to restricting output to downstream firms at the monopoly level. We allow the upstream firm to make an ex-ante capital precommitment. We...
