The paper investigates maternity leave behavior in West Germany for females being employed between 1995 and 2006 using data from the German Socio Economic Panel. The observational study focuses on the investigation of individual and family-related covariate effects on the duration of maternity...

In this paper we show that findings of an apparently instable popularity function of U.S. presidents, as reported in the previous literature, are likely the consequence of the common use of linear estimation techniques. Employing Penalized Spline Smoothing in the context of Additive Mixed Models...

This paper provides new evidence on the outmigration behaviour of foreign-born immigrants. Our analysis is based on data from the German Socio-Economic Panel covering the period 1984 to 2010. A unique feature of our paper is the use of new data from panel-drop out studies, which allows us to...

Empirical studies analyzing the determinants of U.S. presidential popularity have delivered quite inconclusive results concerning the role of economic variables by assuming linear relationships. We employ penalized spline smoothing in the context of semi-parametric additive mixed models and...

One of the major challenges of empirical tax research is the identification and calculation of appropriate tax data. While there is consensus that average marginal tax rates are most suitable for studying the effects of tax policy on economic growth, due to data limitations the calculation of...

This paper makes use of data from the German socio-economic panel to gain new insights into the determinants of unemployment duration in Germany. Due to substantial differences with respect to labour market outcomes we follow a stratified approach with respect to gender and ethnicity. To analyze...

The paper provides new evidence on the outmigration of foreign-born immigrants. We make use of data from the German Socio-Economic Panel and employ penalised spline smoothing in the context of a Poisson-type Generalised Additive Mixed Model (GAMM), which enables us to incorporate bivariate...

Der Beitrag stellt zunächst die grundlegenden Ideen der mit dem Corona-Sonderpreis des Statistischen Bundesamtes ausgezeichneten Arbeiten vor, die sich mit der Schätzung der Übersterblichkeit in den Jahren 2020 und 2021 befassen. Dabei wurde eine altersadjustierte Schätzung der jährlichen...
