We provide new evidence that large firms or establishments are more sensitive than small ones to business cycle conditions. Larger employers shed proportionally more jobs in recessions and create more of their new jobs late in expansions, both in gross and net terms. The differential growth rate...

This paper develops a matching model of the labour market under wage rigidity when hiring decisions are irreversible. There are two types of workers, the skilled and the unskilled. The model is used to analyse whether technological advances may have increased unemployment, and shows that this is...

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...

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...

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...

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....

Does the search and matching model fit aggregate US labour market data? While the model has become an important tool of macroeconomic analysis, recent literature pointed to some significant failures in accounting for the data. This paper aims to answer two questions: (i) Does the model fit the...

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...

This paper proposes a dynamic stochastic general equilibrium model in which the government-consumption multiplier doubles when unemployment rises from 5% to 8%. Theoretically, such countercyclicality arises because of a nonlinearity, namely, that labor supply is convex in a labor market...

Recent research in macroeconomics emphasizes the role of wage rigidity in accounting for the volatility of unemployment fluctuations. We use worker-level data from the CPS to measure the sensitivity of wages of newly hired workers to changes in aggregate labor market conditions. The wage of new...
