We consider the problem of maximizing terminal utility in a model where asset prices are driven by Wiener processes, but where the various rates of returns are allowed to be arbitrary semimartingales. The only information available to the investor is the one generated by the asset prices and, in...

I exploit exogenous changes in school year length in Germany in 1966 and 1967 to study the causal effect of education on health. Controlling for cohort, school track and Federal states fixed effects, which fully control for the assignment into treatment, reveals no differences in body weight,...

There remains great uncertainty about the economic consequences of co-determination in German supervisory boards. Because employee representation on company boards is mandatory, depending on the legal form and size of the company, a direct comparison of those companies that apply...

In empirical studies it often happens that some variables for some units are far away from the other observations in the sample. These extreme observations, or outliers, often have a large impact on the results of statistical analyses – conclusions based on a sample with and without these...

Using data from the Behavioral Risk Factor Surveillance System for 2006, I test recent theoretical predictions on social comparisons influencing individual Body Mass Index (BMI). I find that in particular the average BMI of individuals in the same county-age-gender-cell as the respective...

From the normatively given aims of the macroeconomic equilibrium, which describe the target state of an economy system, necessary conditions are derived at an optimal growth path with maximum consumption and maximum profits on the interest structure of a market economy, by using the golden rule...

We clarify the definition and interpretation of “sustainability economics” (Baumgärtner and Quaas 2010) in response to recent comments by van den Bergh (2010), Bartelmus (2010) and others. For that sake, we distinguish between general and specific definitions of sustainability and...

This paper analyzes the productivity development in the German public theater sector for the seasons 1991/1992-2005/2006. Using a stochastic distance frontier approach that allows to decompose total factor productivity change into different sources we examine (a) whether Baumol’s cost-disease...

We use a long panel data set for four entry cohorts into an internal labor market to analyze the effect of age on the probability to participate in different training measures. We find that training participation probabilities are inverted u-shaped with age and that longer training measures are...

This paper examines a perfectly discriminating contest (all-pay auction) with two asymmetric players. Valuations are endogenous and depend on the effort each player invests in the contest. The shape of the valuation function is common knowledge and differs between the contestants. Some key...
