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 study active labor market policies (ALMP) in a matching model. ALMPs are modelled as a subsidy to job search. Workers differ in their productivity, and search takes place along an extensive margin. An additional job seeker affects the quality of unemployed workers. As a result, the Hosios...

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...

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...

A model of the labour market under firing restrictions and endogenous quits is constructed. It is shown that in the spirit of Blanchard and Summers (1988), the model can generate multiple equilibria, with a low-quits/high-unemployment equilibrium coexisting with a high-quits/low-unemployment...

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 analyse optimal saving of risk-averse households when labour income stochastically jumps between two states. The generalized Keynes-Ramsey rule includes a precautionary savings term. A phase diagram analysis illustrates consumption and wealth dynamics within and between states. There is an...

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....
