The focus of this paper is on the steady state of a two-sector economy with undirected search where employed and unemployed workers can search for jobs, both within a sector and between the sectors. As in the one-sector model, on-the-job search generates wage dispersion among homogeneous...

A worker's job can be improved through on-the-job search (OJS) and job upgrading. Incorporating these external and internal job dynamics into a directed search model, this paper analytically characterizes the socially efficient allocation and quantitatively evaluates the model. The analysis...

This paper argues that a broad class of search models cannot generate the observed business-cycle-frequency fluctuations in unemployment and job vacancies in response to shocks of a plausible magnitude. In the U.S., the vacancy-unemployment ratio is 20 times as volatile as average labor...

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...

We build a directed search model of the labor market in which workers' transitions between unemployment, employment, and across employers are endogenous. We prove the existence, uniqueness and efficiency of a recursive equilibrium with the property that the distribution of workers across...

When workers have incomplete information about their ability, they can learn about this ability by searching for jobs, both while employed and unemployed. Search outcomes yield information for updating the belief about the ability which affects optimal search decisions in the future. Firms...
