Efficient Mechanisms for Mergers and Acquisitions
41 Pages Posted: 17 Jul 2007
We characterize incentive-efficient merger outcomes when payments can be made both in cash and stock. Each firm has private information about both its stand-alone value and a component of the (possibly negative) potential synergies. We study two cases: when transfers can, and cannot, be made contingent on the value of any new firm. When they can, we show that redistributing shares of any non-merging firm generates information rents and provides necessary and sufficient conditions for the implementability of efficient merger rules. When they cannot, private information undermines efficiency more when it concerns stand-alone values than synergies. Here, acquisitions emerge as optimal mechanisms.
