This paper evaluates the effectiveness of the international naval mission in the Gulf of Aden from 2008-2010, both in terms of its counter-piracy and its counter-terrorism objectives. We draw on arguments developed in the literature of law and economics, detailed statistical analyses and a large number of in depth interviews. Counter-piracy operations are a qualified success: their main effects...

Good decision-making often requires people to perceive and handle a myriad of statistical correlations. Notably, optimal portfolio theory depends upon a sophisticated understanding of the correlation between financial assets. In this paper, we examine people's understanding of correlation using a sequence of portfolio-allocation problems and find it to be strongly imperfect. Our experiment uses...

This paper investigates the short-term effects of public smoking bans on individual smoking behavior. In 2007 and 2008, state-level smoking bans were gradually introduced in all of Germany's sixteen federal states. We exploit this variation in the timing of state bans to identify the effect that smoke-free policies had on individuals' smoking propensity and smoking intensity. Using rich...

Several German states recently introduced tuition fees for university education. We investigate whether these tuition fees influence the mobility of university applicants. Based on administrative data of applicants for medical schools in Germany, we estimate the effect of tuition fees on the probability of applying for a university in the home state. We find a small but significant reaction: The...

This article analyzes the effects of an increase in statutory sick pay from 80 to 100 percent of forgone gross wages in Germany. Difference-in-differences approaches show that the increase in generosity decreased employee attendance by about ten percent or one day per employee per year. Heterogeneity in response behavior was of great importance and employee health its main driver. For employers,...
