We explore the conditions under which the "first-order approach" (FO-approach) can be used to characterize profit maximizing contracts in dynamic principal-agent models. The FO-approach works when the resulting FO-optimal contract satisfies a particularly strong form of monotonicity in types, a...

We study the existence of a profitable unemployment insurance market in a dynamic economy with adverse selection rooting in information on future job losses. The new feature of the model is that the insurer and workers interact repeatedly. Repeated interactions make it possible to threaten...

We develop general recursive methods to solve for optimal contracts in dynamic principal-agent environments with hidden states and hidden actions. In our baseline model, the principal observes nothing other than transfers. Nevertheless, optimal incentive-constrained insurance can be attained. We...

We present a Theory of Contracts under costly enforcement in the context of a dynamic relationship between an uninformed buyer and a seller who is privately informed on his persistent cost at the outset. Public enforcement relies on remedies for breach. Private enforcement comes from severing...

This paper studies optimal contracts and monitoring policies in procurement under dynamic adverse selection and moral hazard concerning a cost-reducing investment decision. I assume fixed costs of investment and show that the resulting 'lumpy' investment behavior creates a motive to monitor...

We present a Theory of Contracts under costly enforcement in the context of a dynamic relationship between an uninformed buyer and a seller who is privately informed on his persistent cost at the outset. Public enforcement relies on remedies for breach. Private enforcement comes from severing...

Prompt Corrective Action (PCA) prescribes prompt and deterministic termination of banks with insufficient levels of book-value capital. This paper investigates whether reliance on book-value capital is a good policy choice and if PCA is an optimal regulatory approach. I use a variant of DeMarzo...

We study a multiperiod principal-agent problem with moral hazard in which the agent is required to exert effort only in the initial period of the contract. The effort choice of the agent in this first period determines the conditional distribution of output in the following periods. The paper...

We design a multiple project-funding contract that provides optimal incentives to recipients, in a setting where externalities exist among the multiple projects and where donors and recipients may differ in their valuation of the projects. To do so, we study optimal incentive payments in a...

We present the optimal contract for financing a project that has N stages to be completed sequentially when the principal can not commit to abandone the project before it is completed and the project to be completed is valued by the agent. In a dynamic moral hazard setting, we find that the...
