We estimate the public wage gap in France for the period 1990-2002, both at the mean andat different quantiles of the wage distribution, for men and women separately. We account forunobserved heterogeneity by using fixed effects estimations on panel data and, departingfrom usual practice, allow...

Powell (1986) proposed a quantile regression estimator for censored regression models on the basis of equivariance of quantiles to monotone transformations. In this thesis, censored quantile regression models are generalized using two-parameter Box-Cox transformation to relax the conventional...

The statistical inference based on the ordinary least squares regression is sub-optimal when the distributions are skewed or when the quantity of interest is the upper or lower tail of the distributions. For example, the changes in Total Sharp Scores (TSS), the primary measurements of the...

Collective bargaining in Germany takes place either at the industry level or at the firm level; collective bargaining coverage is much higher than union density; and not all employees in a covered firm are necessarily covered. This institutional setup suggests to distinguish explicitly union...

Diese Arbeit besteht aus empirischen und methodischen Beiträgen zur Literatur über den deutschen Lohnunterschied zwischen Männern und Frauen. Bisher war es aus Mangel an geeigneten Daten nicht möglich, den potentiellen Einfluss von Arbeitgebern bzw. Firmen auf diesen Lohnunterschied zu...

This study analyzes the employment effects of training in East Germany. We propose and apply an extension of the widely used conditional difference-in-differences estimator. Focusing on transition rates between nonemployment and employment, we take into account that employment is a state- and...

Based on unique administrative data, which has only recently become available, this paper estimates the employment effects of the most important type of public sector sponsored training in Germany, namely the provision of specific professional skills and techniques (SPST). Using the inflows into...
