Inequality aversion in long-term contracts

This paper examines a two-period moral hazard model with an inequality-averse agent. We show how the agent's past performance will help the principal to relax incentive compatibility constraints and how the existence of an inequality aversion of the agent affects a level of wage in each period in a long-term contract. In particular, we focus on the performance in period 1 on the level of wage in period 2. We show that the agent's wage in period 2 depends on performance in periods 1 and 2. This implies that the long-term relationship creates the opportunity for intertemporal risk and inequality sharing.
