Der vorliegende Beitrag ist eine Metaanalyse von 99 deutschen Bevölkerungssurveys aus dem GESIS-Datenarchiv, in denen die postmaterialistische Einstellung der Befragten ermittelt wird. Es wird anhand von Mehrebenenmodellen gezeigt, dass sich der Anteil der Postmaterialisten unter Kontrolle von...

Despite of its relevance for science policy and the scientific community, empirical research on doctoral education in Germany is sparse. The few papers available face challenges in the sampling approach: simple random sampling is not possible, because a universal register of PhD candidates in...

We investigate how worries in Germany change across time and age, drawing on both closed-ended questions (which typically list a number of worry items) and open-ended questions answered in text format. We find that relevant world events influence worries. For example, worries about peace peaked...

While social relationships play an important role for individuals to cope with missing market institutions, they also limit individuals' range of trading partners. This paper aims at understanding the determinants of trust at various social distances when information asymmetries are present....

Typically, laboratory experiments suffer from homogeneous subject pools and self-selection 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...

We use a lab-in-the-field experiment to investigate intra-couple labor supply decisions and the division of housework under individual and joint income taxation systems. In order to eliminate problems of endogenous intra-couple time use decisions, we exogenously varied not only the taxation...

We study how website defaults affect consumer behavior in the domain of charitable giving. In a field experiment that was conducted on a large platform for making charitable donations over the web, we exogenously vary the default options in two distinct choice dimensions. The first pertains to...

This paper formalizes the design of experiments intended specifically to study spillover effects. By first randomizing the intensity of treatment within clusters and then randomly assigning individual treatment conditional on this cluster-level intensity, a novel set of treatment effects can be...
