Abstract

This article examines the optimal contract in a bilateral trade model with unobservable relationship-specific investment and renegotiation. In such a setting, a contract plays an additional role that it does not have in the standard holdup model, namely that of transmitting information between the parties. The article shows that a partial-disclosure contract may be optimal and describes the optimal contract. If the investment is cooperative and the information between the trading parties is asymmetric, the optimal contract generally cannot result in the first best, but dispensing with either of these assumptions makes the first-best achievable.
