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...

Do firms reduce employment when their insiders (established, incumbent employees) claim higher wages? The conventional answer in the theoretical literature is that insider power has no influence on employment, provided that the newly hired employees (entrants) receive their reservation wages....

Suppose insiders use their market power to push up their wages, while entrants receive their reservation wages. How will employment be affected? In addressing this question, we focus on the role of on-the-job training. We show that an insider wage hike reduces recession-time employment but, in...

On the basis of aggregate data for the early nineties, we analyse the determinants of unemployment duration for laid-off male workers in Wallonia (Belgium). Our results demonstrate that if ranking in recruitment occurs, the standard Mixed Proportional Hazard specification can be too restrictive,...

We develop and estimate a non-stationary job search model to evaluate a scheme that monitors job search effort and sanctions insured unemployed whose effort is deemed insufficient. The model reveals that such schemes provide incentives to the unemployed to front-load search effort prior to...

Since July 2004 the job search effort of long-term unemployed benefit claimants is monitored in Belgium. We exploit the discontinuity in the treatment assignment at the age of 30 to evaluate the effect of a notification sent at least 8 months before job search is verified. The threat of...

This paper challenges what is the standard account of UK unemployment, namely that the major swings in unemployment over the past 25 years are due predominantly to movements in the underlying empirical “natural rate of unemployment” (NRU). Our analysis suggests that the British NRU has...

The aim of this paper is to analyze and estimate salient characteristics of unemployment dynamics. Movements in unemployment are viewed as "chain reactions" of responses to labor market shocks, working their way through systems of interacting lagged adjustment processes. In the context of...

This paper provides a critique of the "unemployment invariance hypothesis", according to which the behavior of the labor market ensures that the long-run unemployment rate is independent of the size of the capital stock, productivity, and the labor force. Using Solow growth and endogenous growth...

This paper examines the movements in EU unemployment from two perspectives: (a) the NRU/NAIRU perspective, in which unemployment movements are attributed largely to changes in the long-run equilibrium unemployment rate and (b) the chain-reaction perspective, in which unemployment movements are...
