We conduct online field experiments in large real-world social networks in order to decompose prosocial giving into three components: (1) baseline altruism toward randomly selected strangers, (2) directed altruism that favors friends over random strangers, and (3) giving motivated by the...

The use of social networks in the workplace has been documented by many authors, although the reasons for their widespread prevalence are less well known. In this paper we present evidence based on a combined eld-laboratory experiment that social networks are used by employers to reduce worker...

We conduct a field experiment in a large real-world social network to examine how subjects expect to be treated by their friends and by strangers who make allocation decisions in modified dictator games. While recipients beliefs accurately account for the extent to which friends will choose more...

The use of social networks in the workplace has been documented by many authors, although the reasons for their widespread prevalence are less well known. In this paper we present evidence based on a lab experiment that suggests quite strongly that social networks are used by employers to reduce...

We conduct a field experiment in a large real-world social network to examine how subjects expect to be treated by their friends and by strangers who make allocation decisions in modified dictator games. While recipients’ beliefs accurately account for the extent to which friends will choose...

Banning deception in economic experiments does not exclude experiments with participants in the role of experimenters who can gain by deceiving those in the role of participants. We compare treatments with and without possible deception by experimenter-participants to test whether deception...

Gift exchange experiments have demonstrated that norms can affect labor market outcomes and provided an explanation for involuntary unemployment. However, conflicting results from laboratory and field experiments have questioned the relevance of gift exchange and helped spark an ongoing debate...

A large and growing literature has demonstrated that explicit incentives, such as enforceable contracts, can lead agents to withhold effort. We investigate when this behavioral result arises. In an extensive laboratory experiment, we find that imposing control through an enforceable contract is...

How the income of relevant others affects well-being has received renewed interest in the recent literature using subjective data. Migrants constitutes a particularly interesting group to study this question: as they changed environment, they are likely to be concerned by several potential...

We investigate the motives of pro-social behavior in collective decisions in an economic experiment. It compares individual behavior in private and collective decisions in a unified experimental setup. Subjects are given an individual endowment and have to decide how much of it to donate to...
