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...

In a reasonably calibrated Mortensen and Pissarides matching model, shocks to average labor productivity can account for a small portion of the fluctuations in unemployment and vacancies (Shimer (2005)). I add heterogeneity in jobs (matches) with respect to the time the job is created in the...

Shimer (2005a) argues that the Mortensen-Pissarides equilibrium search model of unemployment explains only about 10% of the response in the job-finding rate to an aggregate productivity shock. Some of the recent papers inspired by his critique are reviewed and commented on here. Specifically, we...

Most dynamic stochastic general equilibrium models (DSGE) of the macroeconomy assume that labour is traded in a spot market. Two exceptions (Andolfatto [3], Merz [11]) combine the two-sided search model of Mortenson and Pissarides, [14], [13], [15] with a one-sector real business cycle model....

Although the cyclical aspects of worker reallocation are investigated in numerous studies, only scarce empirical evidence exists for Germany. Kluve, Schaffner, and Schmidt (2009) emphasize the heterogeneity of cyclical influences for different subgroups of workers, defined by age, gender and...

This paper studies the role of capital investment in a search and matching model. I develop an endogenous job separation matching model in which a firm's irreversible capital investment is endogenously determined. The incorporation of capital investment provides an additional channel for firms...

This paper presents a novel monthly dataset of job vacancies in Bogota between 1960 and 2010. The dataset was constructed by counting the number of help-wanted announcements published in the most important newspaper with national circulation—namely, El Tiempo. We describe the methodology used...

This paper considers new business start-up activity within a stochastic equilibrium model of unemployment. The resulting job creation process is both natural and tractable, and generates equilibrium unemployment and vacancy dynamics which match the volatility and persistence observed in the...

Some economic observers argue “structural unemployment” has increased in the wake of the Great Recession, but in this paper we find little support for either of two arguments that suggest that structural unemployment has been on the rise. The first argument focuses on the large increase in...

"Scarce empirical evidence exists for Germany regarding the cyclical aspects of worker reallocation. Furthermore, it is assumed that the cyclical influence on transition rates is the same for all demographic groups. However, one can expect that each subgroup is differentially influenced by the...
