We study a dynamic, decentralized market environment with asymmetric information and interdependent values between buyers and sellers, and characterize the complete set of equilibria. The model delivers a stark relationship between the severity of the information frictions and the time it takes...

We study a dynamic, decentralized market environment with asymmetric information and interdependent values between buyers and sellers, and characterize the complete set of non-stationary equilibria. For a given fraction of low-quality assets, or ``lemons,'' the model describes how prices, the...

In many markets, sellers advertise their good with an asking price. This is a price at which the seller is willing to take his good off the market and trade immediately, though it is understood that a buyer can submit an offer below the asking price and that this offer may be accepted if the...

In a market in which sellers compete by posting mechanisms, we study how the properties of the meeting technology affect the mechanism that sellers select. In general, sellers have incentive to use mechanisms that are socially efficient. In our environment, sellers achieve this by posting an...

I show that multiple equilibria are a general property of economies under full monetary policy discretion. Three simple conditions are sufficient to rule out, generically, a unique equilibrium in a static economy. The key departure from Barro and Gordon (1983) is to consider bounded welfare...

A number of stylized facts have been documented about the extensive margin of trade---which firms export, and how many products they send to how many destinations. We argue that the sparse nature of trade data is crucial to understanding these stylized facts. Typically the number of...

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...
