Many labor market models use both idiosyncratic productivity and a vacancy free entry condition. This paper shows that these two features combined generate an equilibrium comovement between matches on the one hand and unemployment and vacancies on the other hand, which is observationally...

This paper shows analytically and numerically that there are two ways of generating an observationally equivalent comovement between matches, unemployment, and vacancies in dynamic labor market models: either by assuming a standard Cobb-Douglas contact function or by combining a degenerate...

There is strong empirical evidence for Cobb-Douglas matching functions. We show in this paper that this widely found relation between matches on the one hand and unemployment and vacancies on the other hand can be the result of different underlying mechanisms. Obviously, it can be generated by...

This paper shows that the matching function and the Beveridge curve in the United States exhibit strong nonlinearities over the business cycle. These patterns can be replicated by enhancing a search and matching model with idiosyncratic productivity shocks for new contacts. Large negative...

Dieser Beitrag nimmt aus theoretischer und ökonometrischer Sicht zu der Kontroverse über die Bedeutung der qualifikatorischen Lohnstruktur zur Erklärung der Beschäftigungsstruktur Stellung. Basierend auf einer Einteilung in drei Qualifikationsgruppen zeigt sich empirisch, dass die Entlohnung...

Der Beitrag enthält eine Neuschätzung der inflationsstabilen Arbeitslosenquote (NAIRU) für Westdeutschland 1980 bis 1998. Nach einer Darstellung des konzeptionellen Rahmens der NAIRU einschließlich verschiedener Varianten, welche beispielsweise exogenen Schocks und dem Hysterese-Phänomen...
