The Dynamics of Mergers and Acquisitions in Oligopolistic Industries

This paper develops a continuous time real options model to study the interaction between industry structure and takeover activity. In an asymmetric industry equilibrium, firms have an endogenous incentive to merge when restructuring decisions are motivated by operating and strategic benefits. The model predicts that (i) the likelihood of restructuring activities is greater in more concentrated industries or in industries that are more exposed to exogenous shocks; and (ii) the magnitude of returns arising from restructuring to both merger firms and rival firms are higher in more concentrated industries. While recent real options models contend that competition erodes the option value of waiting and hence accelerates the timing of mergers, in our model, increased competition delays the timing of mergers.
