Abstract

This chapter first reviews the economic theory underlying the unilateral competitive effects of mergers, focusing on the Cournot model, commonly applied to homogeneous products; the Bertrand model, commonly applied to differentiated consumer products; and models of auctions and bargaining, commonly applied when a bidding process or negotiations are used to set prices. This chapter then reviews two classes of empirical methods used to make quantitative predictions of the unilateral effects of proposed mergers.
