We present an axiomatic model of choice involving two agents, motivated by the experimental evidence on non-selfish preferences. We distinguish two classes of social preferences, depending on whether they are or not separable. Altruism and spite (Andreoni & Miller, 2002; Cox et al., 2007) are...

Experimental studies of the WTP-WTA gap avoid social trading by implementing an incentive compatible mechanism for each individual trader. We compare a traditional random price mechanism and a novel elicitation mechanism preserving social trading, without sacrificing mutual incentive...

The bias generated by the subjective perception of scarcity on the consumer's choice is discussed from a theoretical perspective. The core idea here discussed is that scarcity is an Lancasterian attribute of the goods which is not endogenously built in the goods, like many physical attributes,...

This paper experimentally investigates a well-known anomaly in portfolio management, i.e. the fact that paper losses are realized less than paper gains (disposition effect). The existence of the disposition effect is documented in a simple risk task which demonstrates that the anomaly is most...

We investigate strategic choices of individuals working for social cooperatives in Italy. Specifically, a 2-players Prisoner’s Dilemma is administered as an attachment to a nationwide survey of nonprofit organizations. We experimentally manipulate social proximity of the participants and...

Group membership increases cooperation in social dilemma games, altruistic donation in dictator games, and fair offers in ultimatum games. While the empirical study of group action has grown rapidly over the years, there is little agreement at the theoretical level on exactly why and how group...

We experimentally investigate social effects in a principal-agent setting with incomplete contracts. The strategic interaction scheme is based on the Investment Game (Berg et al., 1995). In our setting four trustees and one trustor are interacting and the access to choices of peers in the group...

Recent years registered a renewed interest in social interactions. However, due to some well-known identification problems, empirical estimation of peer effects remains quite problematic. To overcome problems of this kind, a database providing detailed information on the sequential structure of...

Deviations from standard game theoretical predictions have been repeatedly observed in basic Dictator Games. Different interpretations have been provided to these deviations. On the one hand, empirical (among others, Forsythe et al., 1994) and theoretical works (among others, Bolton and...
