This paper examines the impact of parental investments on the development of cognitive, mental and emotional skills during childhood using data from a longitudinal study, the Mannheim Study of Children at Risk, starting at birth. Our work offers three important innovations. First, we use...

While there is a broad literature on the general wage effect of training, little is known about the effects of different training forms and about the effects for heterogeneous training participants. This study therefore adds two aspects to the literature on earnings effects of training. First,...

This paper considers the shape invariant modelling approach in semiparametric regression estimation. Nonparametric functions of similar shape are linked by parametric transformations with unknown parameters. A computationally convenient estimation procedure is suggested. √N- consistency of the...

This paper conducts a spatial econometric analysis of the determinants of regional specialisation patterns. Spatial autocorrelation is present, but is mostly due to spatial error autocorrelation. Spatial interaction due to economic interdependencies is only evident for some few labour-intensive...

Consumption based equivalence scales are estimated by applying the extended partially linear model (EPLM) to the 1998 Income and Consumption Survey (EVS) of Germany. The chosen flexible semiparametric specification is able to capture a large variety of functional forms of household expenditure...

Empirical work on continuing training in Germany provides surprisingly divergent evidence on the incidence of training. This makes comparison of econometric analyses of the impact of training on labour market outcomes di?cult. Three large German data sets are used here to bring to light the data...

Im Oktober 1998 befragte das ZEW rund 250 Finanzexperten aus Banken, Versicherungen, Kapitalanlagegesellschaften und großen Industrieunternehmen nach ihren Empfehlungen zur Gestaltung eines Vermögensportfolios zur Altersvorsorge. Dieses Papier untersucht in einem ersten Schritt, ob in...

In this paper, I contrast the quality of part-time jobs - in terms of hourly wage rates - with those of full-timers. Using the Netherlands as a benchmark, helps to assess the size and seriousness of the estimated wage differentials in Germany. Based on two comparable household surveys, I...

Diese Studie versucht Eigenschaften zu identifizieren, die das Beschäftigungswachstum junger deutscher Unternehmen in den neunziger Jahren beeinflussen. Um für die unterschiedlichen wirtschaftlichen Rahmenbedingungen zu kontrollieren, werden die empirischen Analysen getrennt für Ost- und...
