We consider a two-person Cournot game of voluntary contributions to a public good with identical individual preferences, and examine equilibrium aggregate welfare under a separable, symmetric and concave social welfare function. Assuming the public good is pure, Itaya, de Meza and Myles (Econ....

Cooperation norms often emerge in situations, where the long term collective benefits help to overcome short run individual interests, for instance in repeated Prisonerś Dilemma (PD) situations. Often, however, there are different paths to cooperation, benefiting different kinds of actors to...

The measurement of social norms plays a pivotal role in many social sciences.While economists predominantly conduct experiments, sociologistsrather employ (factorial) surveys. Both methods, however, suer from distinctweaknesses. Experiments, on the one hand, often fall short in themeasurement of...

People use moral wiggle room to behave selfish. But does a narrow wiggle room necessarily produce better social outcomes? When people disagree on normative goals, economic theories of self-image predict that narrowing the moral wiggle room will make choices not only less selfish but also even...

People frequently behave non-selfishly in situations where they can reduce their own payoff to help others. It is typically assumed that such pro-social behavior arises because people are motivated by a social preference. An alternative explanation is that they follow a social norm. We test with...

Using a unique experimental data set, we investigate how asymmetric legal rights shape bargainers’ aspiration levels through moral entitlements derived from equity norms and number prominence. Aspiration formation is typically hard to observe in real life. Our study involves 15 negotiations...

This paper provides a survey of recent experimental work in economics focusing on social and economic networks. The experiments consider networks of coordination and cooperation, buyer-seller networks, and network formation

By extending the traditional trust game to settings involving more than one trustee, we study how restricting information flow between trustees influences trust and reciprocity. We start with a theoretical investigation and then report the results of two experiments designed to examine investor...
