This paper studies the dynamics of labor demand at the firm level. Recent studies emphasize the importance of non-convex components in the structure of hiring and firing costs in the form of either fixed or linear adjustment costs. Building from Cooper al. (2005) model and Rota (2004)...

Existing models of equilibrium unemployment with endogenous labor market participation are complex, generate procyclical unemployment rates, and suffer from the usual defects of matching models. We embed endogenous participation in a simple, tractable job market matching model, show analytically...

Using a simple stochastic multi-sector model we show patterns of demand shares on sectors with different productivity coefficients have some expected and some unexpected effects on GDP, sector sizes, the magnitudes of the Okun's law coefficients, and Beveridge curves shifts. The basic stochastic...

Due to increased technological change which lead to an increased demand for skilled workers, it becomes more and more difficult for low skilled workers to find a job. How should a society or political decision makers react? Recently, German politicians are engaged in a discussion about the...

This paper tries to assess which kind of real rigidities can enhance our understanding of inflation and labor market dynamics in a dynamic general equilibrium model with capital and labor market frictions and nominal price rigidities. We particularly introduce real wage rigidities through...

Above market clearing wages are shown to prevail as an outcome of a game in which employers possess and employees lack the ability to coordinate. It is established in a monopolistically competitive framework that it may be optimal for individual firms to coordinate and restrict entry of indirect...

This paper shows that the standard Mortensen-Pissarides framework embedded in a RBC macroeconomic model with risk averse agents, capital and a labor-leisure choice has the ability to match all moments of the ac- tual US-unemployment rate and other labor market variables within tight bounds when...

This paper studies the cyclical properties the standard Mortensen-Pissarides model of labor search and matching embedded in the real business cycles model with capital, risk-averse agents, and lack of private insurance against unemployment risk. The model enables a direct comparison between the...

A number of studies have documented a reduction in aggregate macroeconomic volatility beginning in the early 1980s. Using an empirical model of business cycles, we extend this line of research to state-level employment data, find significant heterogeneity in the timing and magnitude of the...

Theory implies that employment protection will unambiguously decrease job flows. However, cross-country comparisons of annual rates of job reallocation seem to show that employment protection has no discernible effect on job flows. This paper presents a model that shows that employment...
