In a within-subjects experiment we test the relation of risk preferences and charitable giving. Women not only give substantially more than men, but also show an economically significant positive correlation between risk tolerance and donation levels. We find no such correlation for men. Men and...

This paper theoretically and experimentally studies decision-making in risky and social environments. We explore the interdependence of individual risk attitudes and social preferences in the form of inequality aversion as two decisive behavioral determinants in such contexts. Our model and the...

We study the coexistence of strategies in the indirect reciprocity game where agents have access to second-order information. We fully characterize the evolutionary stable equilibria and analyze their comparative statics with respect to the cost-benefit ratio (CBR). There are indeed only two...

We study the coevolution of cooperation, preferences, and cooperative signals in an environment where individuals engage in a signaling-extended prisoner's dilemma. We prove the existence of a cooperative equilibrium constituted by a (set of) limit cycle(s) and stabilized by the dynamic...

We test in a survey the impact of economic preferences on compliance and perception during the Corona pandemic. Results show that economic preferences crucially impact citizens' compliance to policies fighting the crisis. Risk tolerance negatively a↵ects citizens' avoidance of crowds, whereas...

This paper applies the indirect evolutionary approach to study the evolution of inequality aversion in a simplified game of life. The game comprises a dilemma, a problem of coordination, and a problem of distribution as a general framework for the evolution of preferences. In singlegame...

In this paper, we study the rational for an incumbent to launch a second brand when facing potential entry in a market with quality differentiated products and a fringe producer. Depending on market size, costs for a second brand and a potential entrant's setup cost the incumbent might use a...

This paper analyzes seasonal effects and their potential drivers in charitable giving. We analyze whether donations differ between the pre-Christmas shopping season and summer. Our experiment aims to minimize confounding factors and controls for donor heterogeneity. We find that prosocial...

This paper tests motivational crowding out in the domain of charitable giving. A novelty is that our experiment isolates alternative explanations for the decline of giving such as strategic considerations of decision makers. Moreover, preference elicitation allows us to focus on the reaction of...

This paper experimentally tests the relation between subjects' competitiveness and bargaining behavior. Bargaining is investigated in a demand-ultimatum game, where the responder can request a share of the pie from the proposer. The results show that highly competitive proposers earn less, since...
