We consider a very general class of public finance problems that encompasses Ramsey models of optimal taxation as well as economies with limited commitment, private information, and political economy frictions. We identify a sufficient condition to rule out permanent intertemporal distortions at...

This paper studies the long run properties of intertemporal distortions in a broad class of second best economies. Our unified framework encompasses and extends many well known models, such as variants of the Ramsey taxation model with aggregate or idiosyncratic risk, and economies with...

The U.S. non-financial corporate sector became a net lender vis-a-vis the rest of the economy in the early 2000s. We document this fact in the aggregate and firm-level data. We then develop a structural dynamic model with investment to study the firms' financing decisions. Debt is fiscally...

We consider a simple state verification technology in a dynamic private information economy. We find that the marginal benefit may be below the marginal cost of investment under the constrained efficient allocation. In particular, if the planner can verify a the type of a sufficiently large...

Social and private insurance schemes rely on legal action to deter fraud and tax evasion. This observation guides us to introduce a random state-verification technology in a dynamic economy with private information. With some probability, an agent's skill level becomes known to the planner who...
