Ever since the seminal work of Stigler (1962), economists have recognized that information in markets is costly to acquire and can lead to “search frictionsâ€. The remarkable growth in online search has substantially lowered the cost of information acquisition. Despite this, there is...

This paper presents a theory of how factor income shares are determined in an environment with labor market frictions and heterogeneous firms. I assume neither a specific aggregate production function nor competitive factor markets. Instead, I first develop microfoundations for an aggregate...

We present a Search and Matching model with heterogeneous workers (entrants and incumbents) that replicates the stylized facts characterizing the US and the Spanish labor markets. Under this benchmark, we find the Post-Match Labor Turnover Costs (PMLTC) to be the centerpiece to explain why the...

The labor search and matching model plays a growing role in macroeconomic analysis. This paper provides a critical, selective survey of the literature. Four fundamental questions are explored: how are unemployment, job vacancies, and employment determined as equilibrium phenomena? What...

This paper extends Mortensen and Pissarides (1994) by introducing workers' risk aversion. In doing so, it provides a framework within which to study jointly the optimal supply of job security and the allocational and welfare consequences of government intervention in excess of private...

This paper surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...

We evaluate the impacts of a randomized job-fair intervention in which jobseekers and employers can meet at low cost. The intervention generates few hires, but it lowers participants' expectations and causes both firms and workers to invest more in search as predicted by a theoretical model;...
