During the last three decades the ascent of behavioral economics clearly helped tobring down artificial disciplinary boundaries between psychology and economics.Noting that behavioral economics seems still under the spell of the rational choicetradition – and, indirectly, of behaviorism – we...

We run a computerised experiment of network formation where allconnections are bene…cial and only direct links are costly. Players simul-taneously submit link proposals; a connection is made only when bothplayers involved agree. We use both simulated and experimentally gen-erated data to test...

In this paper, we introduce the concept of payoff distortion inthe standard prisoner’s dilemma game when strategies are driven by psychologicalbehaviors. This concept enables to take account each player’s assessmentof the other player’s behavior and the asymmetry of information....

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...

Costly signaling of commitment to a group has been proposed as an explanation forparticipation in religion and ritual. But if the signal’s cost is too small, freeriders willsend the signal and behave selfishly later. Effective signaling may then be prohibitivelycostly. If the average level of...

This paper provides a new way to identify conditional cooperationin a real-time version of the standard voluntary contribution mechanism. Ourapproach avoids most drawbacks of the traditional procedures because it relieson endogenous cycle lengths, which are defined by the number of contributors...

The literature on social preferences provides overwhelming evidence of departuresfrom pure self-interest of individuals. Experiments show that people care about others’well-being and their relative standing. This paper investigates whether this type ofbehavior persists when risk comes into...

Which inequalities among individuals are considered unjust? This paper reportsthe results of an experiment designed to study distributive choices dealing with arbitrarilyunequal initial endowments. In a three-person distribution problem wheresubjects either know or do not know their endowments,...

This paper examines the occurrence and fragility of information cascades in laboratory experiments.One group of low informed subjects make predictions in sequence. In a matchedpairs design, another set of high informed subjects observe the decisions of the first group andmake predictions....

This paper studies the response times of experimental subjects playingthe Ultimatum game in a laboratory setting using monetary incentives.We find that proposals are not significantly correlated with responsetime, whereas responders’ behavior is positively and significantlycorrelated. Hence,...
