Abstract

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