Abstract

The received literature concludes that if scale economies are absent, mergers are often unprofitable under Cornot competition, but always profitable under Bertrand. In a linear demand model with three firms initially, where there are two merger candidates, we show that results will change if we introduce the number of brands as a choice variable.
