To study how a firm can capitalize on a long-term customer relationship, we characterize the optimal contract between a monopolist and a consumer whose preferences follow a Markov process. The optimal contract is nonstationary and has infinite memory, but is described by a simple state variable....

We study the Markov equilibria of a model of free riding in which n infinitely lived agents choose between private consumption and irreversible contributions to a durable public good. We show that the set of equilibrium steady states converges to a unique point as depreciation converges to zero....

This paper presents a political economy theory of fiscal policy. Policy choices are made by a legislature that can raise revenues via an income tax and by borrowing. Revenues can be used to finance a public good, whose value is stochastic, and pork-barrel spending. Policymaking cycles between a...

This paper develops an infinite horizon model of public spending and taxation in which policy decisions are determined by legislative bargaining. The policy space incorporates both productive and distributive public spending and distortionary taxation. The productive spending is investing in a...
