Does It Pay To Be a Woman? Labour Demand Effects of Maternity-Related Job Protection and Replacement Incomes
In countries with strong employment protection laws it is often considered to be unwise to hire a woman in childbearing age because she might get pregnant. However, such labour demand e ects of job protection measures related to maternity leave are often rather anecdotal. To provide analytical evidence, this paper studies the impact of changes in maternity-related job protection in Germany on employment opportunities for women in childbearing age without children for whom the observed e ects should be largely demand-related. Exogenous, discrete policy changes in the German labour market of the 1980s and 1990s constitute the setting for a difference-in-differences analysis of the transition into employment as well as wages. The data for this study are taken from the German Socio-Economic Panel and from the German Microcensus. Doubling the job-protected leave period from 6 months to 12 months between 1986 and 1988 led to an approximately 6% lower probability of being hired for women in childbearing age without a university degree.In addition, I nd a 5-10% increase in wages for women in childbearing age associated with the latter reform. Since this effect disappears when controlling for having a child in the future, this may indicate an increased need to signal commitment by increased effort after the reform
Moving Up a Gear: The Impact of Compressing Instructional Time into Fewer Years of Schooling
Policy-makers face a trade-off between the provision of higher levels of schooling and earlier labour market entries. A fundamental education reform in Germany tackles this trade-off by reducing high school by one year while leaving the total instructional time unchanged. Employing administrative data on all high school graduates in 2002-2013 in Germany, we exploit both temporal and regional variation in the implementation of the reform and study the overall effectiveness of this reform. We find that compressing the high school track by one year reduces the mean high school graduation age by about 10 months. The probability to repeat a grade level in the course of high school increases by 21 percent (3 percentage points), peaking in the final three years before graduation. However, the high school graduation rate is not affected. The results indicate the reform's success in reducing the graduation age, though it stays behind its potential benefits for labour markets and social security schemes because of higher grade repetition rates
