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) over almost five years. In the additional time, students are taught new learning content. On average, the reform improves student performance. However, treatment effects ...

This paper provides evidence on the question of who bears the burden of social security contributions (SSC) in Germany over a long-term horizon. Following Alvaredo et al. (De Econ, 2017) we exploit kinks in the budget set generated by a drop in the marginal SSC rate at earnings caps for health and long-term care insurance. These concave kinks lead to discontinuities in the distributions of gross earnings, ...

In this article, we study judicial behavior at the Judicial Committee of the Privy Council (JCPC). British judges in general, and British high court judges in particular, are perceived to be independent and isolated from political pressure and interference. Furthermore, these judges tend to show a particularly high rate of consensus. This has led many scholars to consider that, contrarily to what holds ...

Against the background of remunicipalisation trends in European public service sectors, this paper estimates firm-level productivity for German electricity retailers and tests whether the ownership type has a significant impact on productivity. We specify a production function for the retail sector with labour and external services as main inputs, which is estimated using a control function approach. ...

In dieser Studie gehen wir der Frage nach, welche Faktoren die einkommensbedingten Unterschiede in der Mortalität erklären können. Auf der Basis des Sozio-oekonomischen Panels (SOEP) werden ereignisanalytische Modelle der Mortalität ab dem Alter 65 geschätzt, die Auskunft über den Mediatoreffekt von acht Faktorenbündeln geben. Als Mediatoren zwischen Einkommen zum Alter 65 und Mortalität werden Bildung, ...

Well-being is often relatively stable across adulthood and old age, but typically exhibits pronounced deteriorations and vast individual differences in the terminal phase of life. However, the factors contributing to these differences are not well understood. Using up to 25-year annual longitudinal data obtained from 4,404 now-deceased participants of the nationwide German Socio-Economic Panel Study ...

Die britische Regierung will im Jahr 2017 den Austritt aus der EU erklären. Dies wird Folgen für die EU-Staaten Ostmittel- und Südosteuropas haben. Die Abwertung des Pfunds nach dem britischen Referendum hat bereits den Wert der Überweisungen von Arbeitsmigranten verringert. Erheblich wären die Folgen, sollte Großbritannien die Arbeitnehmerfreizügigkeit einschränken. Auch auf den Handel und in geringerem ...

Public budgets in Germany developed favorable during the last years. Currently there is a broad discussion on how to spend unexpected budget surpluses: tax reductions and a various number of spending purposes are on the agenda. Many of the proposals overlook that existing surpluses partly reflect special developments and are, thus, only temporary. This part of surpluses indicates no scope for tax reductions ...

Aktuell besteht eine der zentralen politischen Aufgaben in der Integration von Geflüchteten in die Gesellschaft. Integration setzt sich aus Teilprozessen, wie dem Erlernen der deutschen Sprache oder der Arbeitsmarkteinbindung, zusammen. In diesem Bericht betrachten wir diese Teilprozesse für Geflüchtete, die vor allem zwischen 1990 und 2010, nach Deutschland einreisten.

Is it possible to compress instruction time into fewer school years without lowering education levels? A fundamental reform in Germany reduced the length of academic track schooling by one year, while increasing instruction hours in the remaining school years to provide students with a very similar core curriculum and the same overall instruction time. Using aggregated administrative data on the full ...

The emerging literature on power markets with high shares of variable renewable energy sources suggests that the costs of more frequent start-ups of thermal power plants may become an increasing concern. Here we investigate how this develops in Germany, where the share of variable renewables is expected to grow from 14% in 2013 to 34% in 2030. We show that the overall number of start-ups grows by 81%, ...

Constrained transmission capacity in electricity networks may give generators the possibility to game the market by specifically causing congestion and thereby appropriating excessive rents. Investment in network capacity can ameliorate such behavior by reducing the potential for strategic behavior. However, modeling Nash equilibria between generators, which explicitly account for their impact on the ...

ObjectivesThis article analyzes how couples allocate housework against the backdrop of three questions: (1) Does an individual's income—both in absolute and relative terms—influence his or her contribution to housework? (2) If so, does themagnitude of this influence differ by gender? and (3) How important are traditional gender roles on housework allocation?MethodsWe apply panel regression techniques ...

Background: Neighborhood characteristics are important determinants of individual health and well-being. For example, characteristics such as noise and pollution affect health directly, while other characteristics affect health and well-being by either providing resources (e.g. social capital in the neighborhood), which individuals can use to cope with health problems, or limiting the use thereof (e.g. ...

Changes in residual volatility are often used for identifying structural shocks in vector autoregressive (VAR) analysis. A number of different models for heteroskedasticity or conditional heteroskedasticity are proposed and used in applications in this context. The different volatility models are reviewed and their advantages and drawbacks are indicated. An application investigating the interaction ...

We use a tailor-made survey on a Swedish sample to investigate how individuals' relative income affects their demand for redistribution. We first document that a majority misperceive their position in the income distribution and believe that they are poorer, relative to others, than they actually are. We then inform a subsample about their true relative income and find that individuals who are richer ...

Widespread agreement that a political reform is necessary is no guarantee that it is actually undertaken in a timely manner. There is often a delay before action is taken and reform packages that would be most efficient to implement all at once are often done only gradually. We propose a theoretical model explaining this behavior and show that when voters have present-biased, time-inconsistent preferences, ...

We report on two experiments investigating whether there is a gender difference in the willingness to compete against oneself (self-competition), similar to what is found when competing against others (other-competition). In one laboratory and one online market experiment, involving a total of 1,200 participants, we replicate the gender-gap in willingness to other-compete but find no evidence of a ...

To this end, a large data set of German manufacturing establishments and various panel data models are used in order to test the expected non-linear relationship between labour productivity and the use of fixed-term employees. The analysis takes into account the possible distortions that ...
