Managerial delegation and merger incentives

We analyse how the internal organisation of firms affects the correspondence between private and social incentives for horizontal merger. Applying a model of endogenous merger formation in a three-firm asymmetric Cournot industry, we contrast the cases of entrepreneurial and managerial firms. The use of strategic delegation increases both the probability that a merger takes place and the likelihood that the 'wrong' type of merger is undertaken, from a viewpoint of social welfare. This suggests that managerial delegation increases the scope for antitrust policy.
