This paper shows that earnings losses after unemployment increase with age. First, older employees start out with relatively high earnings in comparison to employees without employment interruptions several years before the non-employment spell. This earnings advantage turns into a strong...

Using data from the German Socio-Economic Panel for the years 2000 to 2006 we analyze the determinants and labor market effects of educational dropout. In addition to classical variables like family background and occupation, we examine noncognitive skills and Internet use. Noncognitive skills...

This study tests for financial constraints on R&D investment and how they differ from capital investment. To identify constraints in the access to external capital, we employ a credit rating index. Our models show that internal constraints, measured by mark-ups, are more decisive for R&D than...

We present evidence for a highly significant interaction between state dependence in individual unemployment risk and the business cycle. The disadvantage from having been unemployed in the previous period is smaller in times of relatively high unemployment and larger in times of low...

Der Beitrag untersucht unter Verwendung der Daten des Sozio-ökonomischen Panels für Westdeutschland über den Zeitraum 1984-2005, ob und in welcher Form die individuelle Betriebszugehörigkeitsdauer von konjunkturellen Schwankungen beeinflusst wird. Als Analyseinstrument dient die...

We estimate the effects of R&D on firms' credit ratings and on financial distress. The main purpose is the comparison of firms in Western Germany and Eastern Germany as a transitional economy. Innovative activity has a positive impact on firm value proxied by ratings in Western Germany, but a...

On the basis of a theoretical model, we argue that higher aggregate unemployment affects individual returns to education. We therefore include aggregate unemployment and an interaction term between unemployment and the individual education level in a standard Mincer equation. Our results show...

The real options investment theory shows that greater uncertainty about market revenues reduces current R&D investment by increasing the value of waiting. This paper presents empirical evidence that patent protection mitigates the effect market uncertainty on R&D investment.
