This paper focuses on fraud detection in surveys using Socio-Economic Panel (SOEP) data as an example for testing newly methods proposed here. A statistical theorem referred to as Benford's Law states that in many sets of numerical data, the significant digits are not uniformly distributed, as...

This paper asks whether part-time work makes women happy. Previous research on labour supply has assumed that as workers freely choose their optimal working hours on the basis of their innate preferences and the hourly wage rate, outcome reflects preference. This paper tests this assumption by...

Several clinical trials give information about the impor-tance of individual behaviour for the prevalence of these illnesses. Changes in health relevant behaviour may...

The female share in management positions is quite low in Germany. The higher the hierarchical level, the fewer women there are in such positions.

In 1999, in Germany, the statutory sick pay level was increased from 80 to 100 percent of foregone earnings for sickness episodes of up to six weeks. We show that this reform has led to an increase in average absence days of about 10 percent or one additional day per employee, per year. The...

This study is the first to estimate mothers’ marginal willingness to pay (MWP) for job amenities directly. Its identification strategy relies on German maternity leave length. The key aspect of the maternal leave framework is that mothers can decide whether and when to return to their...

This study estimates the reform effects of a reduction in statutory sick pay levels on various outcome dimensions. A federal law reduced the legal obligation of German employers to provide 100 percent continued wages for up to six weeks per sickness episode to 80 percent. This measure increased...
