This paper studies how imposing norms on contribution behavior affects individuals' intrinsic motivation. We consider the church levy, which the Catholic Church in Germany collects as a charitable donation, despite the fact that the levy is legally a tax. We design a randomized field experiment...

This paper investigates whether risk aversion and impatience are correlated with cognitive ability. We conduct incentive compatible choice experiments measuring risk aversion, and impatience over an annual time horizon, for a representative sample of roughly 1,000 German adults. A measure of...

Recent evidence suggests that self-regulation plays an important role for labor market success. We conducted a randomized natural field experiment embedded in an existing labor market reactivation program to examine the effect of a self-regulation training on long-term unemployed individuals....

Typically, laboratory experiments suffer from homogeneous subject pools and selfselection biases. The usefulness of survey data is limited by measurement error and by the questionability of their behavioral relevance. Here we present a method integrating interactive experiments and...

This study investigates how the first childbirth affects the wage processes of highly attached women. We estimate a flexible fixed effects wage regression model extended with post-birth fixed effects by the control function approach. Register data on West Germany are used and we exploit the...

This study presents descriptive and causal evidence on the role of social environment for the formation of prosociality. In a first step, we show that socioeconomic status (SES) as well as the intensity of mother-child interaction and mothers' prosocial attitudes are systematically related to...

We run a large-scale natural field experiment to evaluate alternative strategies to enforce compliance with the law. The experiment varies the text of mailings sent to potential evaders of TV license fees. We find a strong alert effect of mailings, leading to a substantial increase in...

We conduct a large-scale field experiment in the German labor market to investigate how information provision affects job seekers' employment prospects and labor market outcomes.

This paper reports the results from a controlled field experiment designed to investigate the causal effect of public recognition on employee performance. We hired more than 300 employees to work on a three-hour data-entry task. In a random sample of work groups, workers unexpectedly received...

After World War II, town twinning became popular, notably in Germany. This was mainly a reaction to the war experience, and it was aimed at creating renewed international understanding and co-operation between German cities and cities in other countries. The contacts created by town twinning...
