Alleinlebenden älteren Menschen droht in Corona-Zeiten Vereinsamung

Seit März hat die Corona-Pandemie Deutschland fest im Griff. Weitreichende Beschränkungen des sozialen Lebens wurden vor allem zum Schutz älterer und weiterer besonders gefährdeter Menschen erlassen. Seit Mai werden diese Maßnahmen schrittweise gelockert. Dabei stellt sich verstärkt die Frage, wie trotz der Lockerungen vulnerable Teile der Bevölkerung geschützt werden können. In vielen Ländern wird ...

Tuition Fees and Educational Attainment

Following a landmark ruling by the Constitutional Court in 2005, more than half of Germany’s universities started charging tuition fees, which also applied to incumbent students. We exploit this unusual lack of grandfathering together with register data covering the universe of students to show that tuition fees increased degree completion among incumbent students. Investigating mechanisms, we do not ...

The Impact of the Length of Schooling on the Timing of Family Formation

Individuals typically traverse several life phases before forming a family. We analyse whether changing the duration of one of these phases, the education phase, affects the timing of marriage and childbearing. For this purpose, we exploit the introduction of short school years in Germany in 1966-67, which compressed the education phase without affecting the curriculum. Based on difference-in-differences ...

Difference-in-Differences to Identify Causal Effects of COVID-19 Policies

Policymakers have implemented a wide range of non-pharmaceutical interventions to fight the spread of COVID-19. Variation in policies across jurisdictions and over time strongly suggests a difference-in-differences (DD) research design to estimate causal effects of counter-COVID measures. We discuss threats to the validity of these DD designs and make recommendations about how researchers can avoid ...

Increased Instruction Time and Stress-Related Health Problems among School Children

While several studies suggest that stress-related mental health problems among school children are related to specific elements of schooling, empirical evidence on this causal relationship is scarce. We examine a German schooling reform that increased weekly instruction time and study its effects on stress-related outpatient diagnoses from the universe of health claims data of the German Social Health ...

Does Quality of Early Childhood Education and Care Affect the Home Learning Environment of Children?

Both, a high quality of the Early Childhood Education and Care (ECEC) setting and a high quality of the home learning environment foster children’s development. However, we know little about the interactions between ECEC quality and the home learning environment. We examine whether the child’s attendance in a high ECEC quality setting improves the quality of her home learning environment. We use very ...

School Entry, Afternoon Care and Mothers' Labour Supply

Most literature on the relationship between childcare availability and maternal labour force participation examines childcare for preschool aged children. Yet families must continue to arrange childcare once their children enter primary school, particularly in countries where the school day ends at lunchtime. In this paper we examine the case of Germany, a country that has moved from an exclusively ...

The Effect of Increasing Education Efficiency on University Enrollment: Evidence from Administrative Data and an Unusual Schooling Reform in Germany

We examine the consequences of compressing secondary schooling on students’ university enrollment. An unusual education reform in Germany reduced the length of academic high school while simultaneously increasing the instruction hours in the remaining years. Accordingly, students receive the same amount of schooling but over a shorter period of time, constituting an efficiency gain from an individual’s ...

Increased Instruction Hours and the Widening Gap in Student Performance

Do increased instruction hours improve the performance of all students? Using PISA scores of students in ninth grade, we analyse the effect of a German education reform that increased weekly instruction hours by two hours (6.5 percent) overalmost five years. In the additional time, students are taught new learning content. On average, the reform improves student performance. However, treatment effects ...

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 ...
