Teaching and Statistical Training

The availability of well-educated researchers is necessary for the fruitful analysis of social and economic data. The increased data offer made possible by the creation of the Research Data Centers has resulted in an increased demand for PhD students at the master’s or Diplom levels. Especially in economics, where we find intense competition among the various individual subjects within the course of ...

Tests for non-ignorable panel attrition and their application on wage estimates from the German Socio-Economic Panel (GSOEP)

A Bootstrap Strategy for the Detection of a Panel Attrition Bias in a Household Panel with an Application to the German Socio-Economic Panel (GSOEP)

A bootstrap strategy for detecting non-ignorable panel attrition is proposed. The strategy is based on the diflerence of the original estimate and an estimate that is obtained by reducing the original sample by a second attrition experiment. The attrition propensities are estimated from previous wave information and field work information of the current panel wave. The routine may be used to estimate ...

A penalized spline estimator for fixed effects panel data models

Estimating nonlinear effects of continuous covariates by penalized splines is well established for regressions with cross-sectional data as well as for panel data regressions with random effects. Penalized splines are particularly advantageous since they enable both the estimation of unknown nonlinear covariate effects and inferential statements about these effects. The latter are based, for example, ...

The effects of the first birth timing on women's wages: A longitudinal analysis based on the German Socio-Economic Panel

While the wage effects of a birth, the so-called “motherhood wage gap”, have already been analyzed in more detail, studies exploring the timing of this life event still tend to be rare. Moreover, the large majority of existing evidence on this topic is based on data from the United States. Research using other data sources, for example research based on German data, is almost completely missing. By ...

Marriage, adaptation and happiness: Are there long-lasting gains to marriage?

This paper uses 23 waves of German panel data and investigates if individuals who decide to marry become permanently happier. Following the same persons over several years we show that they do, thereby challenging a number of recent longitudinal studies in psychology and economics which suggest that individuals fully adapt to the positive impact of marriage. Further, we compare different empirical ...
