This paper investigates the gender wage gap in Denmark, the Netherlands, France and Spain by boostrapping the Oaxaca-Blinder decomposition. The boostrap method is used to compute confidence intervals and to perform hypothesis tests for the (disaggregated) explained and unexplained components of the national earnings differentials between men and women. From the subset of paid employees selected...

Database integration is currently solved only for the case of simple structures. Semantics is mainly neglected. It is known but often neglected that database integration cannot be automated. System integration is far more difficult. Both integrations can only be performed if a number of assumptions can be made for the integrated system. Instead of integrating systems entirely cooperation or col...

The complexity of car subsystems and their interaction is growing. This fact, together with the existence of many variants, enforces a trade-off between the quality and coverage of the respective diagnostics and the efforts spent on their development. What is needed is a comprehensive, general (system-independent) and systematic approach to the generation of diagnostics and its automation. This...

This paper documents the magnitude of income mobility in Germany and its distribution across different income positions, using data from the German Socio-Economic Panel. The suggested graphical approach makes it straightforward to identify the portions of the distribution that have the largest impact on aggregate ‘income movement’ indices à la Fields & Ok, and hence offers a starting point to h...
