Banks have historically provided mutual insurance against asset risk, where the insurance arrangement itself was characterized by limited enforcement. This paper shows that a non-trivial interaction between asset and liquidity risk plays a crucial role in shaping optimal banking arrangements in...

This paper analyzes the effects of money injections on interest rates and exchange rates in a model in which agents must pay a Baumol-Tobin style fixed cost to exchange bonds and money. Asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money only...

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,...

Several recent papers provide strong empirical support for the view that an expansionary monetary policy disturbance generates a persistent decrease in interest rates and a persistent increase in output and employment. Existing quantitative general equilibrium models, which allow for capital...

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...

This paper analyzes the effects of money injections on interest rates and exchange rates in a model in which agents must pay a Baumol-Tobin style fixed cost to exchange bonds and money. Asset markets are endogenously segmented because this fixed cost leads agents to trade bonds and money only...

This paper examines a two-country, monetary general-equilibrium model that includes a financial sector, capital mobility, and shocks to technologies and money-growth rates. Capital mobility allows agents in both countries to participate in rewards from relatively favorable shocks realized in...

We examine nominal and real exchange rates, interest rates, prices, and evolutions of real variables in a two-country, monetary general-equilibrium model that includes a financial sector and shocks to technologies and money growth rates. Qualitative properties of the model are provided and...

I develop an asset-pricing model in which financial assets are valued for their liquidity - the extent to which they are useful in facilitating exchange - as well as for being claims to streams of consumption goods. The implications for average asset returns, the equity-premium puzzle and the...
