A large number of financial assets are traded in both exchanges and over-the-counter markets (i.e., centralized and decentralized markets, CM and DM hereafter, respectively). Moreover, as documented by Biais and Green (2019), the 20th century has witnessed a secular migration of asset trade from...

Classic models of fire-sales that emphasize liquidity-constrained natural buyers can-notfully account for the asset fire-sales during the Financial Crisis of 2008. I present a modelto demonstrate that fire-sales may happen even when there is a sizable pool of naturalbuyers and in the absence of...

A rational-expectations equilibrium with positive demand for financial information does exist under fully revealing asset price - contrary to a wide-held conjecture. Generalizing the common additive signal-return model with CARA utility to the family of distributions with moment generating...

We study economies with an essential role for liquid assets in transactions. The model can generate multiple stationary equilibria, across which asset prices, market participation, capitalization, output and welfare are positively related. It can also generate a variety of nonstationary...

We study an over-the-counter (OTC) market with bilateral meetings and bargaining where the usefulness of assets, as means of payment or collateral, is limited by the threat of fraudulent practices. We assume that agents can produce fraudulent assets at a positive cost, which generates endogenous...

How effectively does a decentralized marketplace aggregate information that is dispersed throughout the economy? We study this question in a dynamic setting where sellers have private information that is correlated with an unobservable aggregate state. In any equilibrium, each seller's trading...

I study how trading motives in asset markets affect equilibrium outcomes and welfare. I focus on two types of trading motives -- informational and allocational. I show that while a fully separating equilibrium is the unique equilibrium when trading motives are known, multiple equilibria exist...

We examine a form of adverse selection which arises when short sellers attempt to coordinate a price correction, but stock lenders learn by observing arbitrageurs' arrivals and become better informed about the true timing of an imminent price correction. We refer to this concept as coarse...
