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...

Several contributions, either in economics and Social Psychology literature, have evidenced the negative impact of controlling practices on intrinsic motivation. The aim of the present paper is to experimentally test some implications of a controlling strategy in a simple game, called Big...

The paper experimentally investigates the interactions between restrictions to personal autonomy and reciprocity in a Principal-Agent relationship. Previous experimental contributions have shown that actions aimed at restricting decisional autonomy are likely to reduce reciprocity in trust-...

In a modified dictator game experiment, we study how distributional justice, measured by the proportionality between effort exerted and rewards obtained, and guilt feelings triggered by others’ expectations affect dictator’s choices. We consider these two sources of behavior in isolation and...

We experimentally investigate imitation in investment choices and focus on cognitive aspects of decision making. At this aim, we manipulate three main dimensions of choice: time pressure, normative content of social information, and uncertainty of the investment. We document the existence of...

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 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...

An often-replicated result in the experimental literature on social dilemmas is that a large share of subjects reveal conditionally cooperative preferences. Cooperation generated by this type of preferences is notoriously unstable, as individuals reduce their contributions to the public good in...
