A number of contributions have found evidence for motherhood being a critical life event for women's employment careers. This study presents a detailed model for the du- ration of maternity leave in which young mothers can make a transition into a number of states related to employment and...

In many situations the applied researcher wants to combine different data sources without knowing the exact link and merging rule. This paper introduces a theoretical framework how two different regional administrative data sources can be merged. It presents different merging schemes based on...

In this paper we derive nonparametric bounds for the cumulative incidence curve within a competing risks model with partly identified interval data. As an advantage over earlier attempts our approach also gives valid results in case of dependent competing risks. We apply our framework to...

With the purpose to reduce winter unemployment and to promote all-season employment in the constructions sector, Germany maintains an extensive bad weather allowance system. Since the mid 1990s, these regulations have been subject to several reforms that resemble the range of approaches for...

Diese Arbeit soll einen ersten Einblick in die Sanktionsinstrumente Sperrzeit und Säumniszeit für Leistungsempfänger der Bundesanstalt für Arbeit geben. Die Forschung basiert auf umfangreichen Individualdatensätzen der Bundesanstalt für Arbeit, der IAB-Beschäftigtenstichprobe und...

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...

Consumption based equivalence scales are estimated by applying the extended partially linear model (EPLM) to the 1998 Income and Consumption Survey (EVS) carried out in Germany. In this model the equivalence scales are identified by virtue of nonlinearities in household demand. Therefore, the...
