Gerlach and Stephan (1994) proposed a test based on the idea that the wage premium, the part of the wage which is not explained by the stock of human capital, should help predict variables such as career expectations (quit, change occupation, leave the labour force) and some job characteristics...

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...

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...

This paper provides a snapshot of the stock of immigrants in Germany using the 1995 wave of the Microzensus with a particular emphasis on distinguishing first- and second-generation migrants. On the basis of this portrait, we draw attention to the empirically most relevant groups of immigrants...

In recent years a number of panel estimators have been suggested for sample selection models, where both the selection equation and the equation of interest contain individual effects which are correlated with the explanatory variables. We review and compare some of these estimators, and apply...

This paper presents a life cycle model for the demand for health, and derives empirical specifications that distinguish between permanent and transitory wage responses. Using panel data, we estimate dynamic health and health input demand equations. We find evidence of negative transitory wage...

This paper provides a preliminary assessment of recent reforms of German employment promotion policy. While several recent studies analyze the impact of measures of employment promotion for the case of Germany, no comparable study exists on the aggregate level, thus precluding any assessment of...

Assessing the migration potential and predicting future migration streams are among the most relevant, yet least well understood topics of migration research. The usual approach taken to address aggregate-level prediction problems is to fit ad hoc specifications to historical data, and to...
