STATA ist ein umfangreiches Programm zur statistischen Analyse (Siehe die Seite des Herstellers zu weiteren Informationen: www.stata.com) und liegt mittlerweile in Version 9 .0 vor. Urspünglich war STATA fast ausschliesslich befehlsgesteuert (etwa im Gegensatz zu SPSS), nur sehr wenige...

We consider general social choice environments with private values and correlated types. Each agent's matrix of conditional probabilities satisfies the full rank condition. We show that for any Bayesian incentive compatible mechanism there exists a dominant strategy incentive compatible...

A continuous and a discrete rating scale were implemented for a single item happiness question in a representative survey. A randomized controlled experiment enables unique analyses on data quality and distributions, which suggest superiority of the continuous scale. Results raise doubts about...

Despite the social importance of awards, they have been largely disregarded by academic research in economics. This paper investigates whether a specific, yet important, award in economics, the John Bates Clark Medal, raises recipients’ subsequent research activity and status compared to a...

Most professional economists believe that economist in general are more selfish than other persons and that this greater selfishness is due to economic education. In this paper we offer empirical evidence against this widely held belief. Using a unique data set about giving behaviour to two...

In recent years a large number of experimental studies have documented the existence of strong reciprocity among humans. Strong reciprocity means that people willingly repay gifts and punish the violation of cooperation and fairness norms even in anonymous one-shot encounters with genetically...

Business students are portrayed as behaving too egoistically. The critics call for more social responsibility and good citizenship behavior on the part of business students. We present evidence of pro-social behavior in business students. Every student at the University of Zurich has to decide...

Yet, little is known about the driving forces behind informal sanctions. We systematically examine the determinants of informal sanctions by a...

Volunteer work is an increasingly large, yet ill-understood sector of the economy. We show that monetary rewards undermine the intrinsic motivation of volunteers. A unique data set from Switzerland allows us to assess the effects of financial rewards on the effort put into volunteer work. There...
