A new methodology is described which tests between various equilibrium theories of unemployment using matching data. The Paper shows how to correct econometrically for temporal aggregation effects, where the econometrician’s aim is to identify a matching process using data which is recorded...

Similar durations but lower flows into unemployment gave Europe lower unemployment rates than the United States until the 1970's. But since 1980, higher durations have kept unemployment rates in Europe persistently higher than in the U.S. A general equilibrium search model with human capital...

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....

Many workers believe that personal contacts are crucial for obtaining jobs in high-wage sectors. On the other hand, firms in high-wage sectors report using employee referrals because they help provide screening and monitoring of new employees. This Paper develops a matching model that can...

In this paper, we present a matching model with adverse selection that explains why flows into and out of unemployment are much lower in Europe compared to North America, while employment-to-employment flows are similar in the two continents. In the model, firms use discretion in terms of whom...

This paper analyzes the contribution of the socioeconomic and demographic composition of the pool of employed and unemployed individuals to the dynamics of the labor market in different phases of the business cycle. Using individual level data from the Current Population Survey (CPS), we...

The decisions of firms on investment and hiring play a crucial role in business cycle fluctuations. This paper explores their dynamic behavior in the presence of frictions. It does so within a unified framework, stressing their mutual dependence and placing the emphasis on their joint,...

Extensive literature demonstrates that workers with high tenure suffer large and persistent earnings losses when they are displaced. We study the reasons behind these losses in a tractable search model that includes a lifecycle dimension, endogenous job mobility, and worker- and...

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...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...
