I study a repeated principal–agent game with long‐term output contracts that can be renegotiated at will. Actions are observable but not contractible, so they can only be incentivized through implicit agreements formed in equilibrium. I show that contract renegotiation is a powerful tool for incentive provision, despite the stationarity of the environment. Continuation contracts are designed to punish deviations in noncontractible behavior. If the equilibrium actions are observed, these contracts are renegotiated away. This form of anticipated renegotiation results in welfare improvements over outcomes attainable by one‐period contracts or by long‐term contracts that are not renegotiated. When the principal is not protected by limited liability, first‐best outcomes are attainable regardless of the impatience of the players. Equilibrium strategies are shown to satisfy various concepts of renegotiation‐proofness.

We study relational contracts between a firm and a worker with mutual uncertainty about match quality. The worker’s actions are publicly observed and generate both output and information about the match quality. We show that the relational contracts may be inefficient. We characterize the inefficiency through a holdup problem on the contemporaneous output. In the frequent action limit, these inefficiencies persist if and only if information degrades at least at the same rate at which impatience vanishes. We characterize optimal relational contracts and show that they involve actions that yield both a lower payoff and less information than another action. (JEL D83, D86, J22, J31, J41, J63)

We study the optimal design of a disinflation plan by a planner who lacks commitment and has imperfect control over inflation. The government's reputation for being committed to the plan evolves as the public compares realized inflation to the announced targets. Reputation is valuable as it helps curb inflation expectations. At the same time, plans that are more tempting to break lead to larger expected reputational losses in the ensuing equilibrium. Taking these dynamics into consideration, the government announces a plan which balances promises of low inflation with dynamic incentives that make them credible. We find that, despite the absence of inflation inertia in the private economy, a gradual disinflation is preferred even in the zero-reputation limit.

We study the optimal design of a disinflation plan by a planner who lacks commitment. Having announced a plan, the Central banker faces a tradeoff between surprise inflation and building reputation, defined as the private sector's belief that the Central bank is committed to the plan. Some plans are harder to sustain: the planner recognizes that paving out future grounds with temptation leads the way for a negative drift of reputation in equilibrium. Plans that successfully create low inflationary expectations balance promises of lower inflation with dynamic incentives that make them more credible. When announcing the disinflation plan, the planner takes into account these anticipated interactions. We find that, even in the zero reputation limit, a gradual disinflation is preferred despite the absence of inflation inertia in the private economy.
