Abstract
This paper studies a continuous-time, finite-horizon contracting problem with renegotiation and dynamic inconsistency arising from non-exponential discounting. The problem is formulated as a dynamic game played among the agent, the principal and their respective future “selves”, each with their own discount function. We identify the principal optimal renegotiation-proof contract as a Markov perfect equilibrium (MPE) of the game, prove that such an MPE exists, and characterize the optimal contract via an extended Hamilton-Jacobi-Bellman system. We solve the optimal contract in closed-form when discounting is a function of the time-difference only and demonstrate the applicability of the results in several different settings.
