Two thirds of US unemployment volatility is due to fluctuations in workers' job finding rate. In search and matching models, aggregate productivity shocks generate such fluctuations: through firms recruiting effort, they affect the rate at which workers and firms come into contact....

We develop a quantitative equilibrium model that features tax deductibility of employer-provided coverage, non-discrimination restrictions, fixed costs of coverage and firms that hire discrete numbers of workers in frictional labor markets. We use the calibrated model to understand what drives...

We construct and analyze a tractable search model of money with a non-degenerate distribution of money holdings. Analytical tractability comes from modeling decentralized exchange as directed search, which makes the monetary steady state block recursive. By adapting lattice-theoretic techniques,...

At any given point of time in an actual economy, some individuals hold more money than other individuals do. This non-degenerate distribution of money holdings among individuals is a rationale for a range of policies designed for reallocating liquidity among individuals. However, monetary theory...

In this paper, we develop a tractable model of the labor market featuring on-the-job search and aggregate fluctuations.

We document five facts about price dispersion.

This paper is a study of the shape and structure of the distribution of prices at which an identical good is sold in a given market and time period. We find that the typical price distribution is symmetric and leptokurtic, with a standard deviation between 19% and 36%. Only 10% of the variance...
