We investigate the hypothesis of failed integration and low social mobility of immigrants. For this purpose, an intergenerational assimilation model is tested empirically on household survey data and validated against administrative data provided by the Italian Embassy in Germany. In line with...

We estimate Frisch labour supply functions for married women using information on desired hours, under the assumptions that these are based on a smooth convex approximation of the budget constraint. The minimum distance approach used allows for correlated random effects both in the wage and in...

When studying particular subgroups of a population, like for instance lone parents, the econometrician typically has few observations at hand. In such a situation, it is vital to take advantage of any valid complementary information that may be available. In this paper we illustrate, for the...

Bei der Vereinheitlichung der Lebensverhältnisse in Ost- und Westdeutschland spielen die Arbeitseinkommen eine zentrale Rolle. Nach der Übernahme des westdeutschen Tarifsystems werden auch in Ostdeutschland die Arbeitseinkommen durch Tarifverhandlungen von Arbeitnehmer- und...

In the face of complex budget constraints the assumption of rationally acting individuals having complete knowledge of the tax system is a theoretical borderline. The specific issues examined in this study are (i) to what extent do consumers (here married women) perceive their true marginal tax...

This paper addresses three major aspects of firms' process innovative activity: forward- looking behaviour, uncertainty w.r.t. returns of R&D investments, and oligopolistic competition on the product market. Assuming that R&D expenditures are cost-reducing investments, we derive an Euler...

This paper uncovers ongoing trends in idiosyncratic earnings volatility across generations by decomposing residual earnings auto-covariances into a permanent and a transitory component. We employ data on complete earnings life cycles for prime age men born 1935 through 1974 that covers earnings...
