Previous research indicates that risky and uncertain marginal returns from the public good significantly lower contributions. This paper presents experimental results illustrating that the effects of risk and uncertainty depend on the employed parameterization. Speci?cally, if the value of the...

The satisficing approach is generalized and applied to finite n-person games.Based on direct elicitation of aspirations, we formally define the conceptof satisficing, which does not exclude (prior-free) optimality but includesit as a border case. We also review some experiments on strategic...

On a heterogeneous experimental oligopoly market, sellers choose a price,specify a set-valued prior-free conjecture about the others' behavior, andform their own profit-aspiration for each element of their conjecture. Weformally define the concepts of satisficing and prior-free optimality...

In a public goods experiment, subjects can vary over a period of stochasticlength two contribution levels: one is publicly observable (their cheap talkstated intention), while the other is not seen by the others (their secretintention). When the period suddenly stops, participants are restricted...

We experimentally examine how group identity affects trust behaviorin an investment game. In one treatment, group identity isinduced purely by minimal groups. In other treatments, group membersare additionally related by outcome interdependence establishedin a prior public goods game. Moving...

Based on an axiomatically derived provision rule allowing community members to endogenously determine which, if any, public project should be provided, we perform experiments where (i) not all parties benefit from provision, and (ii) the projects' costs can be negative. In the tradition of legal...

We investigate experimentally whether the protégés' reaction to paternalism depends on the consequences of the paternalistic action to their well-being. We find that protégé punish a paternalist restricting their freedom of choice. Yet, this negative reaction is not based on principled...

Often in cooperative situations, many aspects of the decision-making environment are uncertain. We investigate how cooperation is shaped by the way information about risk is presented (from description or from experience) and by differences in risky environments. Drawing on research from risky...

In the last decades, there has been a large volume of research showing that emotions do have relevant effects on decision-making. We contribute to this literature by experimentally investigating the impact of four specific emotional states - joviality, sadness, fear, and anger - on risk...

We use information on students´ past participation in economic experiments, as stored in our database, to analyze whether behavior in public goods games is affected by experience (i.e., previous participation in social dilemma-type experiments) and history (i.e., participation in experiments of...
