We experimentally investigate social effects in a principal-agent setting with incomplete contracts. The strategic interaction scheme is based on the well-known Investment Game (Berg et al., 1995). In our setting four agents (i.e., trustees) and one principal (i.e., trustor) are interacting and...

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...

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...

The focus of this paper is on altruism and coordination among children. A special form of altruism (ethical altruism) is investigated by means of experiments. The definition of altruism used here follows from A. Sen’s concept of obligation, i.e. behaviour that produces advantage for someone...

This is an experiment on the effect of norm application in a public good game. We want to investigate whether a control norm affects the contribution level differently, only in relation to the way in which the norm is applied in the game. We compare the amount of public good provided in two...

Inspired by Karl Polanyi’s writings on three allocation modes, namely reciprocity, exchange and redistribution, we first tested a reciprocity ring with ten players. The baseline treatment, with no possibility of socialisation, displayed very low levels of allocative efficiency. Consistently...
