Germany has the lowest birth rate among all OECD countries. To encourage fertility, the federal government has recently introduced a set of reforms that led to a substantial expansion of public child care for under three year old children. Using administrative county-level data, we exploit...

Using an epidemiological approach, we study the cultural influence on fertility outcomes of first- and second-generation female immigrants based on a 1% sample of the German population. We proxy for culture in the country of origin using total fertility rates from the year of migration, survey...

Models built on the classical quality-quantity trade-off predict an increase in child quality and a decrease in child quantity in poor developing countries when parental wealth and educational levels increase. This paper tests this prediction empirically in a cross-sectional framework with data...

Based on the German Socio-economic Panel (SOEP), we show that household consumption drops and saving rises significantly within four years after a child moves out of a household. Per capita consumption of parents is approximately leveled up to that of childless peers after all children are gone....

The paper studies the design of couples income taxation when consumption and labor supply decisions within the couple are made in a cooperative way according to some bargaining scheme. Specifically, the couple maximizes a weighted sum of the spouses utilities. In the first part of the paper, the...

Understanding how households form their long-term saving and investment decisions to shoulder risks not covered by social security systems has been of primary importance in all the countries which, like Germany, introduced major reforms to face the challenges of an aging population. This paper...

When grades lose their informative value because the percentage of students receiving the best grade rises without any corresponding increase in ability, this is called grade inflation. Conventional wisdom says that such grade inflation is unavoidable since it is essentially costless to award...

We benefit from the Bologna reform to show how course and program policies affect academic achievement. We examine two similar programs at the business school of a major European university, which were both reformed. Time lags in the reforms allow us to estimate the difference in the differences...

This paper examines field experiment in which we encourage the use of computer-based tests (quizzes) through a set of non-financial incentives and test their effect on effort and performance of students. Our identification strategy exploits cross-cohort experimental variation in assessment rules...

We use the recent introduction of tuition fees at public universities in seven of the sixteen German states to identify the effects of tuition fees on university enrollment of first-year students at German public universities. Our study differs from previous research in two important ways....
