We propose a novel theory of equilibrium price dispersion in product markets with search frictions. As in Diamond (1971), buyers search for sellers sequentially. In contrast to Diamond (1971), buyers do not meet all sellers with the same probability. Specifically, a fraction of the...

In this paper, we develop a general stochastic model of directed search on the job. Like in the analogous models of random search on the job, the state of the economy in our model includes the infinite-dimensional distribution of workers across different employment states (unemployment, and...

In this paper, we construct a tractable search model of money with a non-degenerate distribution of money holdings. We model search as a directed process in the sense that buyers know the terms of trade before visiting particular sellers, as opposed to undirected search that has dominated the...

In this paper, we develop a tractable model of the labor market where workers search for jobs both while unemployed and while on the job. Search is directed in the sense that each worker chooses to search for the offer that provides the optimal tradeoff between the probability of obtaining the...

How much of a worker's lifetime experience in the labor market is due to human capital accumulation versus luck? We build a life-cycle model of directed search in the labor market, in which workers move between the states of unemployment, employment and across employers because of differences in...

I find that—when shocks are sufficiently persistent—prices are fully flexible.

Inflation and unemployment are central issues in macroeconomics. While much progress has been made on these issues by incorporating frictions using search theory, existing models analyze either unemployment or inflation. We develop a framework to analyze unemployment and inflation together. This...

There are two facts about the world that we take as given: First the "law of one price" is false -- one can find many different prices for what appears to be, beyond reasonable doubt, the same good. Second, prices are set in nominal terms and appear, beyond reasonable doubt, to be sticky -- some...
