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...

A key question in labor market research is how the unemployment insurance system affects unemployment rates and labor market dynamics. We revisit this old question studying the German Hartz reforms. On average, lower separation rates explain 76% of declining unemployment after the reform, a fact...

This paper provides a comprehensive evaluation of benefit sanctions, i.e. temporary reductions in unemployment benefits as punishment for noncompliance with eligibility requirements. In addition to the effects on unemployment durations, we evaluate the effects on post-unemployment employment...

To increase their transition from welfare to work, benefit recipients in the municipality of Rotterdam were exposed to various financial incentives, including both carrots to sticks. Once their benefit spell exceeded one year, welfare recipients were entitled to a reemployment bonus if they...

We study how changes in the maximum benefit duration affect the inflow into unemployment in the Netherlands. Until August 2003, workers who became unemployed after age 57.5 were entitled to unemployment benefits until the age of 65, after which they would receive old age pensions. This...

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...

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable. We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...

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...
