We study optimal incentives in a principal-agent problem in which the agent's outside option is determined endogenously in a competitive labor market. In equilibrium, strong performance increases the agent's market value. When this value becomes sufficiently high, the threat of the agent's...

In this paper, we show that a simple, linear capital tax---the kind used in the Ramsey analysis---can be optimal in a Mirrlees economy with private information. We extend the Mirrlees approach to optimal taxation by studying taxes side-by-side with another institution, rather than in isolation....

We study optimal incentives in a principal-agent problem in which the agent's outside option is determined endogenously in a competitive labor market. In equilibrium, strong performance increases the agent's market value. When this value becomes sufficiently high, the threat of the agent's...

In this paper, we propose a theory of unsecured consumer credit and personal bankruptcy based on the optimal trade-off between incentives and insurance. We solve a fairly standard dynamic moral hazard problem, in which agents’ private effort decisions influence the life-cycle profiles of their...

Did market failures cause the 2007-08 financial crisis? While economists have made substantial progress exploring this question, the answer remains unclear. The answer is important because financial regulation that does not address a specific market failure risks causing new inefficiencies and...

This article studies a tractable theoretical model of optimal consumption and saving decisions with endogenous retirement. Particular attention is paid to the impact of an increase in the risk of losing one’s job on the optimal path of consumption and wealth accumulation. Even if one does not...

Pecuniary externalities often serve as a rationale for government intervention into financial markets. This article reviews the theory of market provision of liquidity in a Diamond-Dybvig economy and examines whether or not the possibility of retrade leads to pecuniary externalities and market...

We study a continuous-time version of the optimal risk-sharing problem with one-sided commitment. In the optimal contract, the agentʼs consumption is a time-invariant, strictly increasing function of a single state variable: the maximal level of the agentʼs income realized to date. We...

In this article, we describe a time-consistency problem that can arise in the government's policy toward insolvent financial firms. We present this problem using a simple model in which shareholders of a large financial firm can raise low-cost debt financing and take on an excessive amount of...
