Previous research does not teach us much about the role of music for skill development. Learning a musical instrument during childhood may affect educational opportunities by improving cognitive skills, teaching non-cognitive skills or sending positive signals to school teachers. Our study is...

We present a model of opinion formation where individuals repeatedly engage in discussion and update their opinion in a social network similarly to the DeGroot model. Abstracting from the standard assumption that individuals always report their opinion truthfully, agents in our model may state...

Friedrich Froebel, a German pedagogue, established the first kindergarten worldwide in Thuringia in 1839. We study the spatial dissemination of the kindergarten movement in Germany in the 19th and beginning of the 20th century. Spatial dissemination can be explained by the cultural proximity,...

We investigate whether working time is related to the intensity of income comparisons and relative income. Our simple theoretical model demonstrates that the effects of relative income concerns depend on whether an individual can choose contractual working hours and/or overtime. In the empirical...

This paper shows how conflicting normative views of fair contribution rules can be used to design sequential contribution mechanisms to foster human cooperation in heterogeneous populations. Our model predicts that a sequential mechanism which solicits contributions first from wealthy actors...

In this paper we analyze how rati cation uncertainty impacts the optimal terms of international environmental agreements (IEAs). We relax the frequent assumption of countries as unitary actors by modeling the rati cation stage through uncertain preferences of a ratifying agent (e.g. the pivotal...

We analyze the provision of a step-level public good in an experiment. Specifically, we investigate how the order of moves and the introduction of a second step-level affects public-good provision. We find that the sequential-move game improves public-good provision and payoffs. An additional...

We analyze the interplay of group identity and inter-group conflict in a contest where each of two conflicting groups can develop either a group or an individualistic identity. Contest structures impact on the adoption of identities which themselves influence behavior in the contest. We show the...

Which decision rule should we use to make a binary collective choice? While voting procedures are applied ubiquitously, they are criticized for being inefficient. Using monetary transfers, efficient choices can be made at the cost of a budget imbalance. Is it optimal to do so? And why are...

We investigate whether peer punishment is an efficient mechanism for enforcing cooperation in an experiment with a long time horizon. Previous evidence suggests that the costs of peer punishment can be outweighed by the benefits of higher cooperation, if (i) there is a sufficiently long time...
