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, Gacirc;rleanu and Pedersen (2005) to allow for more general preferences and idiosyncratic shock structure,...

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

We study how trading frictions in asset markets affect the distribution of asset holdings, asset prices, efficiency, and standard measures of liquidity. To this end, we analyze the equilibrium and optimal allocations of a search-theoretic model of financial intermediation similar to Duffie,...

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...

We study liquidity and systemic risk in high-value payment systems. Flows in high-value systems are characterized by high velocity, meaning that the total amount paid and received is high relative to the stock of reserves. In such systems, banks rely heavily on incoming funds to finance outgoing...

This paper studies the relationship between the arrival of potential investors and market liquidity in a search-based model of asset trading. The entry of investors into a specific market causes two contradictory effects. First, it reduces trading costs, which then attracts new investors (the...

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...

We use minute-by-minute daily transaction-level payments data to document the cross-sectional and time-series behavior of the estimated prices and quantities negotiated by commercial banks in the fed funds market. We study the frequency and volume of trade, the size distribution of loans, the...

We develop a model of the market for federal funds that explicitly accounts for its two distinctive features: banks have to search for a suitable counterparty, and once they meet, both parties negotiate the size of the loan and the repayment. The theory is used to answer a number of positive and...
