Applying an evolutionary framework, we investigate how a reputation mechanism and a buyer insurance (as used on Internet market platforms such as eBay) interact to promote trustworthiness and trust. Our analysis suggests that the costs involved in giving reliable feedback determine the gains...

In auctions a seller offers a commodity for sale and collects the revenue. In fair division games the object is collectively owned by the group of bidders who equally share the revenue. We run an experiment in which the participants face four types of allocation games (auctions and fair division...

Bilateral joint ventures, such as marriage, are economically inspired by their prospects of labor division and specialization. However, specialization makes the partnerwho investsmore in relation-specificqualificationsmore exploitable (holdup problem). In a two-person experiment we study...

Evolutionary game theory is often used to analyze the evolution of moral preferences. A few studies also examine the coevolution of preferences and an institutional aspect of the decision environment. Allowing the adaptation of just one institutional aspect such as litigation or legal insurance...

Conflit et coopération sociaux sont le plus souvent conçus en termes de jeux simples, non répétés, effectués deux par deux, symétriques et simultanés tels que le dilemme du prisonnier, 'chicken', assurance ou 'stag hunt'. Il nous semble qu'un tel ensemble d'exemples donne une optique...

We experimentally examine the efficiency and profitability of two different procurement auctions allowing for quality differences across products. We compare the vector auction with more competition on the sellers' side with a half-auction, reflecting actual procurement practice - an auction for...

Applying an indirect evolutionary approach with endogenous preference formation, we show that a legal system can induce players to reward trust even if material incentives dictate to exploit trust. By analyzing the crowding out or crowding in of trustworthiness implied by various verdict rules,...

Applying an evolutionary framework, we investigate how a reputation mechanism and abuyer insurance (as used on Internet market platforms such as eBay) interact to promote trustworthinessand trust. Our analysis suggests that the costs involved in giving reliable feedbackdetermine the gains from...

Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor my...
