This paper studies the optimal level of discretion in policymaking. We consider a fiscal policy model where the government has time-inconsistent preferences with a present bias toward public spending. The government chooses a fiscal rule to trade off its desire to commit to not overspend against its desire to have flexibility to react to privately observed shocks to the value of spending. We analyze the optimal fiscal rule when the shocks are persistent. Unlike under independent and identically distributed shocks, we show that the ex ante optimal rule is not sequentially optimal, as it provides dynamic incentives. The ex ante optimal rule exhibits history dependence, with high shocks leading to an erosion of future fiscal discipline compared to low shocks, which lead to the reinstatement of discipline. The implied policy distortions oscillate over time given a sequence of high shocks, and can force the government to accumulate maximal debt and become immiserated in the long run.

This article studies optimal relational contracts when the value of the relationship between contracting parties is not commonly known. I consider a principal-agent setting where the principal has persistent private information about her outside option. I show that if the principal has the bargaining power, she wants to understate her outside option to provide strong incentives and then renege on promised payments, while if the uninformed agent has the bargaining power, the principal wants to overstate her outside option to capture more surplus. I characterize how information is revealed, how the relationship evolves, and how this depends on bargaining power. (JEL C78, D82, D83, D86)

This paper studies a model of long-term contracting for experimentation. We consider a principalagent relationship with adverse selection on the agent's ability, dynamic moral hazard, and private learning about project quality. We find that each of these elements plays an essential role in structuring dynamic incentives, and it is only their interaction that generally precludes efficiency. Our model permits an explicit characterization of optimal contracts.
