We show that in a search/matching model with endogenous participation in which workers are heterogeneous with respect to market productivity, satisfying the Hosios rule leads to excessive vacancy creation. The reason is that the marginal worker does not internalize the effect of his or her...

The empirical literature on employer learning assumes that employers learn about unobserved ability differences across workers as they spend time in the labor market. This article describes testable implications that arise from this basic hypothesis and how they have been used to quantify the...

This paper investigates spatial correlation in the matching process of vacant jobs and job seekers. The importance of the interactions of regional labor markets in West Germany is highlighted in several dimensions. We test for spatial autocorrelation in regional hires, unemployment and vacancy...

The objective of this paper is to construct and quantitatively assess an equilibrium search model with on-the-job search and general human capital accumulation. In the model workers enter the labour market with different abilities and firms differ in their productivities. Wages are dispersed...

This paper investigates the effects of labour migration and openness to trade on regional skill endowments across the European Union at a time of increased economic integration. Using regional data from Eurostat's Regio database and the open web source Openflight for the period 1998-2010 we test...

The labor market differs from other markets in many respects. Most important is that those who supply labor also have to deliver it in person. It means firstly that the work environment and organization of work are important for those who deliver labor, since they are in the work place....

This paper describes IZAΨMOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZAΨMOD consists of three components:...

This paper studies the speed at which workers' pre-tax earnings respond to tax changes along the intensive margin. We do so in the context of Germany, where a large discontinuity - or notch - in the tax schedule induces sharp bunching in the earnings distribution. We analyze earnings responses...

While economic studies often assume that labor markets are in equilibrium, there may be specialized labor markets that are likely in disequilibrium. We develop a new methodology to improve the estimation of a reduced form disequilibrium model from the existing models by incorporating...
