Abstract

This paper analyzes the effects of horizontal mergers in vertically related industries. In a successive oligopoly model with an intermediate market, we show that horizontal mergers creating size effects are relatively more profitable downstream than upstream. Furthermore, concentration in an industry reduces the incentives to merge in the vertically related industries. These results hold in a merger game endogenising the merger process.
