The over-the-counter theory of the fed funds market: a primer
We present a dynamic over-the-counter model of the fed funds market, and use it to study the determination of the fed funds rate, the volume of loans traded, and the intraday evolution of the distribution of reserve balances across banks. We also investigate the implications of changes in the market structure, as well as the effects of central bank policy instruments such as open market operations, the Discount Window lending rate, and the interest rate on bank reserves.

Inflation, output and welfare
This paper studies the effects of anticipated inflation on aggregate output and welfare within a search-theoretic framework. We allow money-holders to choose the intensities with which they search for trading partners, so inflation affects the frequency of trade as well as the quantity of output produced in each trade. We consider the standard pricing mechanism for search models, i.e., ex post bargaining, as well as a notion of competitive pricing. If prices are bargained over, the equilibrium is generically inefficient and an increase in inflation reduces buyers? search intensities, output ...

Search in asset markets: market structure, liquidity, and welfare
This paper investigates how market structure affects efficiency and several dimensions of liquidity in an asset market. To this end, we generalize the search-theoretic model of financial intermediation of Darrell Duffie et al. (2005) to allow for entry of dealers and unrestricted asset holdings.

A model of TFP
This paper proposes an aggregative model of Total Factor Productivity (TFP) in the spirit of Houthakker (1955-1956). It considers a frictional labor market where production units are subject to idiosyncratic shocks and jobs are created and destroyed as in Mortensen and Pissarides (1994). An aggregate production function is derived by aggregating across micro production units in equilibrium. The level of TFP is explicitly shown to depend on the underlying distribution of shocks as well as on all the characteristics of the labor market as summarized by the job-destruction decision. The model is ...

Search in asset markets
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, Grleanu and Pedersen (2005) to allow for more general preferences and idiosyncratic shock structure, unrestricted portfolio choices, aggregate uncertainty and entry of dealers. With a fixed measure of dealers, we show that a steady-state equilibrium exists and is unique, and provide a condition on preferences under which a reduction in trading frictions leads to an increase in the price of the asset. We ...

Liquidity in asset markets with search frictions
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, so market participants can accommodate trading frictions by adjusting their asset positions. We show that these individual responses of asset demands constitute a fundamental feature of illiquid markets: they are a key determinant of bid-ask spreads, trade volume, and trading delays - all the ...

Asset prices and liquidity in an exchange economy
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 risk-free rate puzzle, are explored in a version of the model that nests the work of Mehra and Prescott (1985).

A unified framework for monetary theory and policy analysis
Search-theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential. However, tractable versions usually have strong assumptions that make them ill suited for discussing some policy questions, especially those concerning changes in the money supply. Hence, most policy analysis uses reduced-form models. The authors propose a framework, designed to help bridge this gap, that is based explicitly on microeconomic frictions, but allows for interesting macroeconomic policy analyses. At the same time, the model is analytically tractable and ...

Asset prices, liquidity, and monetary policy in the search theory of money
I present a search-based model in which money coexists with equity shares on a risky aggregate endowment. Agents can use equity as a means of payment, so shocks to equity prices translate into aggregate liquidity shocks that disrupt the mechanism of exchange. I characterize a family of optimal monetary policies, and find that the resulting equity prices are independent of monetary considerations. I also study monetary policies that target a constant, but nonzero, nominal interest rate, and find that to the extent that a financial asset is valued as a means to facilitate transactions, the ...
