In a recent paper Konrad and Thum (2014) present a model that shows that unilateral pre-commitment reduces the likelihood of agreement in bilateral negotiations over the provision of a public good when parties have private information over their contribution costs. We test the model in a...

We study how taxes and subsidies affect portfolio choices in a laboratory experiment. We find highly significant differences after intervention, even though the net income is identical in all our treatments and thus the decision pattern of investors should be constant. In particular, we observe...

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).

Jost [Jost, L., 2006. Entropy and diversity. Oikos, 113: 363-374.] recently discussed Hill's [Hill, M., 1973. Diversity and evenness: a unifying notation and its consequences. Ecology, 54: 427-431.] effective number of species and concluded by naming it the "true" diversity. In this note we...

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...

In a series of experiments we show that people learn to play the efficient outcome in an open-ended rent-seeking game. This result persists despite quite different experiment environments and designs, like different propensities of competition, group sizes etc., and is interpretable as a...

In this paper, we attempt to renew the interest in marginal employment subsidies. Such subsidies are paid only for a firm's additional employment exceeding some reference level and create larger employment stimuli at lower fiscal costs than general wage subsidies for all workers. If the hiring...
