Abstract
We extend the strategic contract model where the owner designs incentive schemes for her manager before the latter takes output decisions. Firstly, we introduce private knowledge regarding costs within each owner–manager pair. Under adverse selection, we show that delegation involves a trade‐off between strategic commitment and the cost of an extra informational rent linked to decentralization. Which policies will arise in equilibrium? We introduce in the game an initial stage where owners can simultaneously choose between control and delegation. We show that if decision variables are strategic substitutes, choosing output control through a quantity‐lump sum transfer contract is a dominating strategy. If decision variables are strategic complements, this policy is a dominated strategy. Further, two types of dominant‐strategies equilibrium may arise: in the first type, both principals use delegation; in the second one, both principals implement delegation for a low‐cost manager and output control for a high‐cost one.
