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 investigates social preferences towards unemployment and inflation in the United States. Estimating a popularity function with monthly data for the recent Obama administration, we find that U.S. voters react strongly to both unemployment and inflation. However, reducing unemployment...

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...

The paper investigates female wage profiles in West-Germany between 1984 and 2008 using data from the German Socio Economic Panel. The empirical study focuses on the short-run wageloss due to childcare and the long-run wage-profile in post-birth employment, respectivly. This is compared with...

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 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...

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...
