Structural remedies as a signaling device

Abstract

We analyze the effects of structural remedies on merger activity when the Antitrust Agency (AA) cannot observe a proposed merger’s efficiency type. Provided the AA follows a consumer surplus standard, an efficient merger type is doomed to over-fix with its divestiture proposal in a pooling equilibrium, which is also possible under separation.
