We develop an equilibrium model of on-the-job search with ex-ante heterogeneous workers and firms, aggregate uncertainty and vacancy creation. The model produces rich dynamics in which the distributions of unemployed workers, vacancies and worker-firm matches evolve stochastically over time. We...

This paper presents a theory explaining the labor market matching process through microeconomic incentives. There are heterogeneous variations in the characteristics of workers and jobs, and firms face adjustment costs in responding to these variations. Matches and separations are described...

Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...

This paper analyzes the effects of different wage cyclicalities on labor market flow dynamics at the establishment level. We derive a model that allows for heterogeneous wage cyclicalities across firms over the business cycle and confront the theoretical results with the new AWFP dataset, which...

In this paper, we analyze the connection between value added, wages, and labor market ows at the establishment level. For this purpose, we first develop a simple model to illustrate the expected comovement of these variables. For the empirical analysis, we link the new German Administrative Wage...

We present a generalization of the standard random-search model of unemployment in which firms hire multiple workers and in which the hiring process is time-consuming as well as costly. We follow Stole and Zwiebel (1996a,b) and assume that wages are determined by continuous bargaining between...

Based on the counting of Help-wanted advertisements in print newspapers, we build national vacancy indexes and vacancy rates for Colombia for the period 1976 - 2012. The result is the first dataset capturing the evolution of vacancies for Colombia and the first one covering such a long period...

This paper incorporates search and matching frictions in the labor market into a New Keynesian model. In contrast to the literature, the labor market activity takes place in the (Calvo-staggered) price-setting sector. Matching frictions lead price-setting firms to negotiate wage rates with their...

Recently, a number of authors have argued that the standard search model cannot generate the observed business-cycle-frequency fluctuations in unemployment and job vacancies, given shocks of a plausible magnitude. We use data on the cost of vacancy creation and cyclicality of wages to identify...

All else equal, higher wages translate into higher inflation. More rigid wages imply a weaker response of inflation to shocks. This view of the wage channel is deeply entrenched in central banks’ views and models of their economies. In this paper, we present a model with equilibrium...
