Social and natural sciences employ a number of different measures of diversity. The presents paper surveys those depending on the distribution of abundances among a given set of categories. Characteristic properties of the measures are generalized and a unifying notation is derived. It is argued...

In this note I show that Tsallis entropy (Tsallis, 1988) is not unique in the class of non-additive, selfweighted and quasilinear means. A characterization is given which disproves a result in Dukkipati et al. (2005a,b) and Dukkipati et al. (2006).

This paper puts three of the most prominent specifications of ‘other-regarding’ preferences to the experimental test, namely the theories developed by Charness and Rabin, by Fehr and Schmidt, and by Andreoni and Miller. In a series of experiments based on various dictator and prisoner’s...

Many of real-world public-goods are characterized by a marginal per capita return (MPCR) close to zero and have to be provided by large groups. Up until now, there is almost no evidence on how large groups facing a low MPCR behave in controlled public-good laboratory experiments involving...

We apply the Day Reconstruction Method to compare unemployed and employed people with respect to their subjective assessment of emotional affects, differences in the composition and duration of activities during the course of a day, and their self-reported life satisfaction. Employed persons are...

We use modified dictator games in which the productivity of taking or giving is varied. Subjects have to decide which of the different games will be payoff relevant in the end. We can show that the behavior of dictators does not depend on the productivity of their gifts, but that their behavior...

This paper provides a critical re-examination of Rubinstein’s survey in which he questions the way of teaching economics. The observations obtained in our new survey cast some doubts on the original findings, and in particular, question Rubinstein’s conjecture that our students’ views on...

We conduct a framed field experiment with 245 employed persons (no students) as subjects and a real tax, which is levied on the subjects' income from working in our real effort task. In our first three treatments, the net wage is constant but gross wages are subject to different constant...

We investigate the stability of individual behavior in a repeated public good experiment over time by reinviting subjects back to the lab up to four times in one week intervals. We exclude effects due to learning about others' behavior and reputation building by employing a non-learning and...
