Managerial optimism and investment choice

This paper analyzes whether it might be desirable for a firm to hire an overoptimistic manager to commit to a certain R&D strategy. I consider a Cournot model with an ex‐ante R&D stage where firms can invest in cost reduction before product market competition takes place. I show that firms want to hire overoptimistic managers and argue that a manager's type may serve as a substitute for strategic delegation via contracts. Copyright © 2010 John Wiley & Sons, Ltd.
