A large supplier (principal) contracts with a small firm (agent) to repeatedly provide working capital in return for payments. The total factor productivity of the agent is private and follows a Markov process. Moreover, the agent is less patient than the principal. We solve for the optimal...

Multiple long run players play one amongst multiple possible stage games in each period. They observe and recall past play and are aware of the current stage game being played, but are maximally uncertain about the future evolution of stage games. This setup is termed an uncertain repeated game....

Many transactions in the marketplace rely on hard (or verifiable) information about the underlying value of the intended exchange, typically through certification--- housing, diamonds, bonds being cases in point. What is the class of Pareto efficient certifications for such scenarios? This paper...

A large supplier (principal) contracts with a small firm (agent) to repeatedly provide working capital in return for payments. The total factor productivity of the agent is private and follows a Markov process. Moreover, the agent is less patient than the principal. We solve for the optimal...

Dynamic contracts allow principal to relax future incentive constraints by backloading-- agent posts a bond which is liquidated over time. This is costless with equal access to capital, captured by equal discount rates. Here unequal discounting is introduced in a canonical screening problem...

In the sale of many timed goods such as airline tickets, hotel booking and concert seats, the analyst observes time and price of sale. This paper builds a theory of dynamic pricing which helps the analyst rationalize these observables. The main friction here is private and evolving valuation of...

Financial constraints preclude many surplus producing economic transactions, and inhibit the growth of many others. This paper models financial constraints as the interaction of two forces: the agent has persistent private information and is strapped for cash. The wedge between the optimal and...

This paper combines a canonical epidemiology model of disease dynamics with government policy of lockdown and testing, and agents' decision to social distance in order to avoid getting infected. The model is calibrated with data on deaths and testing outcomes in the Unites States. It is shown...
