The paper sheds some light on the education returns in Germany in the post war period. After describing higher education in Germany the current stand of higher education financing within the single states is presented. In six states tuition fees will be introduced in 2007/08 and discussions are going on in even some more. In the second part of the paper an empirical analysis is done using longitudinal data from the German social pension system. The analysis over the whole lifecycle renders results which proof that the higher education advantages are quite remarkable and might be a justification for more intensified financing by tuition fees. But all this has to be embedded into an encompassing strategy of tax and social policy, especially to prevent a strengthened process of social selection, which would be counterproductive for an increased and highly qualified human capital in Germany.
Economy vs. history
(2004)
The aim of this study is to examine in which cases economic forces or historical singularities prevail in the determination of the long-run distribution of firms. We develop a relatively general model of heterogenous firms' location choice in discrete space. The main force towards an agglomerated structure is the reduction of transaction costs for consumers if firms are located closely, whilst competition and transport costs work towards a more disperse structure. We then assess the importance of the initial conditions by simulating and comparing the resulting distribution of firms for identical economic parameters but varying initial settings. If the equilibrium distributions of firms are similar we conclude that economic forces have prevailed, while differences in the resulting distributions indicate that 'history' is more important. The (dis)similarity of distributions of firms is calculated by means of a measure, which exhibits a number of desirable features.

Dieses Promotionsvorhaben wird versuchen den Begriff der Due-Diligence im Rahmen des Menschenrechts- und Umweltschutzes weiterzuentwickeln. Dieser Terminus verweist auf einen vernünftigen Verhaltensstandard und wird öfters zum Schädigungsverbot in Verbindung gebracht. Ein bekanntes Synonym dafür ist die „Sorgfaltspflicht“. Nach dieser Norm müssen alle voraussehbaren Verletzungsrisiken (Personen-, Sach- und Umwelt) durch die Ergreifung von allen nötigen und angemessenen Maßnahmen vorgebeugt werden (s. z.B. Trail-Smelter und Korfu-Kanal Entscheidung). Dieser Begriff wird gegenwärtig weltweit verwendet um Globalisierungsprobleme zu adressieren, wie z.B. der mangelnde Klimaschutz oder die mangelnde Reglementierung von Transnationalen Unternehmen. Die Emergenz dieser offenen und allgemeinen Norm ist eindeutig und wird durch die Tatsache erleichtert, dass sie in viele Rechtssysteme vorhanden ist. Zum Beispiel, in dem bekannten Urgenda v. Holland Fall, fordert der Gerichtshof von Den Haag vom Staat eine angemessenere Aufsicht im Klimaschutz, da die ursprünglichen Reduktionsziele von Treibhausgasemissionen nicht die wissenschaftlichen Anforderungen entsprachen. Dieser Fall hat viele andere Klagen inspiriert. Der französische Gesetzgeber verpflichtet darüber hinaus seit kurzem mit dem Gesetz zur „devoir de vigilance“ herrschende Unternehmen zur Veröffentlichung eines ‚Sorgfaltsplans‘, so dass die Auswirkungen des gesamten Unternehmens auf die Menschenrechte und die Umwelt effektiv vorgebeugt werden. Dieses Gesetz hat auch die letzten UN-Vertragsverhandlungen bzgl. Multinationalen Unternehmen geprägt. In Anbetracht dessen, wird diese rechtsvergleichende Studie die Verrechtlichung der Norm und ihre Verbreitung in anderen Rechtssysteme untersuchen, so dass der Menschenrechts- und Umweltschutz effektiv gewährleistet werden kann, auch wenn die Politik und Unternehmen es verhindern wollen.
Drinking is Different!
(2020)
Unhealthy behavior can be extremely costly from a micro- and macroeconomic perspective and exploring the determinants of such behavior is highly important from an economist’s point of view. We examine whether locus of control (LOC) can explain alcohol consumption as an important domain of health behavior. LOC measures how much an individual believes that she is in control of the consequences of her own actions for her life’s future outcomes. While earlier literature showed that an increasing internal LOC is associated with increased health-conscious behavior in domains such as smoking, exercise or diets, we find that drinking seems to be different. Using German panel data from the Socio-Economic Panel (SOEP) we find a significant positive effect of having an internal LOC on the probability of moderate and regular drinking. We suggest and discuss two likely mechanisms for this relationship and find interesting gender differences. While social investments play an important role for both men and women, risk perceptions are especially relevant for men.

Expanding public or publicly subsidized childcare has been a top social policy priority in many industrialized countries. It is supposed to increase fertility, promote children’s development and enhance mothers’ labor market attachment. In this paper, we analyze the causal effect of one of the largest expansions of subsidized childcare for children up to three years among industrialized countries on the employment of mothers in Germany. Identification is based on spatial and temporal variation in the expansion of publicly subsidized childcare triggered by two comprehensive childcare policy reforms. The empirical analysis is based on the German Microcensus that is matched to county level data on childcare availability. Based on our preferred specification which includes time and county fixed effects we find that an increase in childcare slots by one percentage point increases mothers’ labor market participation rate by 0.2 percentage points. The overall increase in employment is explained by the rise in part-time employment with relatively long hours (20-35 hours per week). We do not find a change in full-time employment or lower part-time employment that is causally related to the childcare expansion. The effect is almost entirely driven by mothers with medium-level qualifications. Mothers with low education levels do not profit from this reform calling for a stronger policy focus on particularly disadvantaged groups in coming years.
We examine how the gender of business-owners is related to the wages paid to female relative to male employees working in their firms. Using Finnish register data and employing firm fixed effects, we find that the gender pay gap is – starting from a gender pay gap of 11 to 12 percent - two to three percentage-points lower for hourly wages in female-owned firms than in male-owned firms. Results are robust to how the wage is measured, as well as to various further robustness checks. More importantly, we find substantial differences between industries. While, for instance, in the manufacturing sector, the gender of the owner plays no role for the gender pay gap, in several service sector industries, like ICT or business services, no or a negligible gender pay gap can be found, but only when firms are led by female business owners. Businesses in male ownership maintain a gender pay gap of around 10 percent also in the latter industries. With increasing firm size, the influence of the gender of the owner, however, fades. In large firms, it seems that others – firm managers – determine wages and no differences in the pay gap are observed between male- and female-owned firms.
In this paper, we study one channel through which communication may facilitate cooperative behavior – belief precision. In a prisoner’s dilemma experiment, we show that communication not only makes individuals more optimistic that their partner will cooperate but also increases the precision of this belief, thereby reducing strategic uncertainty. To disentangle the shift in mean beliefs from the increase in precision, we elicit beliefs and precision in a two-stage procedure and in three situations: without communication, before communication, and after communication. We find that the precision of beliefs increases during communication.
Labor unions’ greatest potential for political influence likely arises from their direct connection to millions of individuals at the workplace. There, they may change the ideological positions of both unionizing workers and their non-unionizing management. In this paper, we analyze the workplace-level impact of unionization on workers’ and managers’ political campaign contributions over the 1980-2016 period in the United States. To do so, we link establishment-level union election data with transaction-level campaign contributions to federal and local candidates. In a difference-in-differences design that we validate with regression discontinuity tests and a novel instrumental variables approach, we find that unionization leads to a leftward shift of campaign contributions. Unionization increases the support for Democrats relative to Republicans not only among workers but also among managers, which speaks against an increase in political cleavages between the two groups. We provide evidence that our results are not driven by compositional changes of the workforce and are weaker in states with Right-to-Work laws where unions can invest fewer resources in political activities.
