Taking up the discussion surrounding the reliability of the IAB reports on the stock of vacancies in Germany in this journal (ZAF, issue 1/2005), this paper clears up misunderstandings, corrects incorrect statements, and presents further new arguments. The paper is intended to show that it would...

Wir konzentrieren unsere Anmerkungen auf den - nach Scherl - zentralen Punkt der Diskussion, nämlich die Frage, ob die Zahl der angebotenen 'sofort zu besetzenden Stellen' in der IAB-Erhebung korrekt erfasst wird. Des weiteren befassen wir uns mit dem ausgesprochenen Verdacht der...

This article introduces the German job vacancy survey (EGS). Its data are valuable because employers' recruitment processes and decisions are little-noticed through the empirical literature on matching processes on the labour market. This is due to the fact that administrative data on job...

We develop a simple search equilibrium model of workplace training and education based on two features. First, investment in education improves job-related learning skills and reduces training costs burdened by firms. Second, firms with vacant skilled job slots can choose between recruitment...

This paper deals with empirical matching functions. The paper is innovative in several ways. First, unlike in most of the existing literature, matching functions are estimated not only on aggregate, but also on disaggregate levels which is unusual due to the scarcity of appropriate data....

We develop an equilibrium directed search model of the labor market where workers can simultaneously apply for multiple jobs. The main result is that all equilibria exhibit wage dispersion despite the fact that workers and firms are homogeneous. Wage dispersion is driven by the simultaneity of...

In the demographic change, a prolongation of individual employment and thus of beginning a new employment in later stages of the work life is of growing importance. On the base of microeconomic data (establishment panel of the IAB), this paper analyses firms' characteristics correlating with...

This paper analyzes an urn-ball matching model in which workers decide how intensively they sample job openings and apply at a stochastic number of suitable vacancies. Equilibrium is not constrained efficient; entry is excessive and search intensity can be too high or too low. Moreover, an...

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...
