Abstract

In a framework with an upstream monopoly and a downstream duopoly, we analyze the impact of convex costs on the downstream level. In constrast to the case of constant marginal costs, vertical integration does not imply complete market foreclosure. While the nonintegrated downstream ¯rm receives a strictly positive amount of the intermediate good, the downstream allocation is ine±cient. However, a parametrized example indicates that competition at the downstream level may increase aggregate welfare.
