IZA Discussion Paper No. 11044
Katrin John, Stephan L. Thomsen

We use data from a gender-neutral dictator and public goods game setting to analyze differences in other-regarding preferences between boys and girls aged 10 to 17. The results indicate a higher mean of dictator giving, degree of egalitarian decisions and lower frequency of selfish decisions, free-riding and efficiency concerns for...

Concurrently with a steady increase of the supply of college educated workers, recent evidence for the U.S. indicated a decline in the demand for and the real wages of this group after 2000. We investigate empirically, whether there has been a similar trend in Germany. Based on comprehensive, long-run administrative...

IZA Discussion Paper No. 9878

Work complexity can be an important factor contributing to the observed employment and wage developments. Using German data, we find that it increased substantially between 1986 and 2012. Work complexity was higher for high-educated employees in the past but differences have leveled out in 2012 due to a steeper increase...

IZA Discussion Paper No. 9507
revised version forthcoming in: German Economic Review, 2017

Most German states have reformed university preparatory schooling during the last decade by reducing its duration from 13 to 12 years without changing the graduation requirements. In this paper, we use nationwide data on high school graduates and apply a difference-in-differences approach to evaluate the reform effects on post-secondary education...

IZA Discussion Paper No. 9334

This paper investigates whether individual control-perception affects the probability of becoming poor, and vice versa, whether poverty experiences can be detrimental to these traits later on. The former relation is intuitive as control related traits underlay many idiosyncratic determinants of poverty. Though traits like control-perception are known to stabilize towards...

IZA Discussion Paper No. 8976

The undersupply of spots in German daycare facilities for toddlers challenges parents' possibilities to work. To ease the situation, the government implemented a new law entitling every child between ages one and three to daycare supervision for about four hours per day. Nevertheless, the stressed situation of matching demand and...

Less than a decade ago, several German states introduced tuition fees for university education. Despite their comparatively low level, fees were perceived by the public to increase social injustice, and have been abolished. Whereas other studies have shown no effect on enrollment, we analyze the effects on students' budgets. To...

Benefit sanctions imposed on non-compliant welfare recipients are a new element in the German welfare system. In practice, the sanction policy and the application of sanctions vary considerably across the 439 welfare agencies. Based on combined administrative and survey data, these differences are used as instrumental variables to estimate the...

In this paper we evaluate the employment effects of job creation schemes on the participating individuals in Germany. Job creation schemes are a major element of active labour market policy in Germany and are targeted at long-term unemployed and other hard-to-place individuals. Access to very informative administrative data of the...

This paper focuses on the effects of vocational training programmes on the duration of unemployment in Eastern Germany. We use information from administrative data of the Federal Employment Office. To allow for observable and possible unobservable influences we apply a multivariate mixed proportional hazard model. Furthermore, particular interest is spent...
