positions that require small reallocations. In such circumstances, welfare can increase if the government steps in, purchases private assets on its own account, and resells them when the economy recovers.

We study the dynamics of dealers' inventories during an asset market crash, described as a temporary, negative shock to outside investors' aggregate asset demand. We consider a class of dynamic market settings where trading between dealers and outside investors is subject to delays and requires...

This paper studies the long-run effects of anticipated inflation on output and welfare within a search-theoretic framework. We allow money-holders to choose the intensities with which they search for trading partners, so the frequency of trades is endogenous. We consider the standard pricing...

We study the efficiency of dealers' liquidity provision and the desirability of policy intervention in over-the-counter (OTC) markets during crises. Our theory emphasizes two key frictions in OTC markets: finding counterparties takes time, and trade is bilateral, with quantities and prices...

We study the efficiency of liquidity provision by dealers and the desirability of policy intervention in over-the-counter (OTC) markets during crises. We emphasizes two OTC frictions: finding counterparties takes time, and trade is bilateral and involves bargaining. We model a crisis as a shock...

We construct a model in which capital competes with fiat money as a medium of exchange, and establish conditions on fundamentals under which fiat money can be both valued and socially beneficial. When the socially efficient stock of capital is too low to provide the liquidity agents need, they...

We develop a search-theoretic model of financial intermediation and use it to study how trading frictions affect the distribution of asset holdings, asset prices, efficiency and standard measures of liquidity. A distinctive feature of our theory is that it allows for unrestricted asset holdings,...

We develop a search-theoretic model of financial intermediation in an over-the-counter market and study how trading frictions affect the distribution of asset holdings and standard measures of liquidity. A distinctive feature of our theory is that it allows for unrestricted asset holdings, so...

We investigate how trading frictions in asset markets affect portfolio choices, asset prices and efficiency. We generalize the search-theoretic model of financial intermediation of Duffie, Gârleanu and Pedersen (2005) to allow for more general preferences and idiosyncratic shock structure,...
