In the last decades one of the main engines of foreign trade growth has been innovation, the process of embedding knowledge in production processes. The purpose of this paper is to supply evidence favoring the hypothesis that innovation contributes positively to export performance when we...

Support of training has been one of the most important instruments of active labor market policy in East Germany. This paper attempts an evaluation of the effects of training on future employment and future wages of trainees. The analysis distinguishes between measures within and outside of the...

The major contribution of this paper is finding a new and general approach to decomposing log-wage differentials when selection effects are present. We divide the observed log-wage differentials between two groups into 1) differentials in predicted log-wages computed using observed individual...

This paper introduces a new and simple decomposition method for a binary choice model that is equivalent to the Blinder-Oaxaca decomposition analysis for wage differentials. The decomposition method is first developed for a single probit model and later generalized to a simultaneous equations...

Care of stroke patients costs considerably more in specialized stroke units (SU) compared to care in general medical wards (GMW) but the technology may be cost effective if it leads to significantly improved outcomes. While randomized control trials show better outcomes for stroke patients...

In this article, I analyze the changes in wage inequality in the eastern region, western region and reunified Germany a decade after reunification. For that purpose, I use data from the German Socio-Economic Panel for the period 1999 - 2006, and implement the decomposition methodologies of...

The study analyses the gender pay gap in private-sector management positions in Germany based on data from the German Socio-Economic Panel Study (SOEP) for the years 2001-2008. It focuses in particular on gender segregation in the labor market, that is, on the unequal distribution of women and...

Studies of neighbourhood effects often attempt to identify causal effects of neighbourhood characteristics on individual outcomes, such as income, education, employment, and health. However, selection looms large in this line of research and it has been repeatedly argued that estimates of...

We employ CPS data to analyze the sources of hourly real wage changes in the United States for 1976 to 2016 at various quantiles of the wage distribution. We account for the selection bias from the annual hours of work decision by developing and implementing an estimator for nonseparable...

Sample selection models attempt to correct for non-randomly selected data in a two-model hierarchy where, on the first level, a binary selection equation determines whether a particular observation will be available for the second level (outcome equation). If the non-random selection mechanism...
