Field experiments with asymmetric commons dilemmas have shown that groups who are able to derive high social efficiency also had higher equity compared to groups who were not able to derive significant levels of social efficiency. These findings resemble the high productivity in long-lasting...

We study racial discrimination by simultaneously selling identical products on eBay in pairs of auctions posted under different racially identifying names. We detect significant price differences, which are indicative of in-group biases. White names receive higher prices for distinctively white...

The article reports the results of a field experiment used to study dishonest behavior in a natural setting. Customers in a restaurant in tables of one or two diners who paid with cash received excessive change of either 10 or 40 Shekels (about $3 or $12). A majority of customers (128 out of...

We propose a new organizing scheme for classifying types of experiments. In addition to the standard categories of laboratory and field experiments, we suggest a new category: “extra-laboratory experiments.” These are experiments that have the same spirit as laboratory experiments, but are...

This study investigates whether cooperation in an indefinitely repeated prisoner's dilemma is sensitive to the complexity of cooperative strategies. An experimental design which allows manipulations of the complexity of these strategies by making either the cooperate action or the defect action...

Can pro-social preferences lead to dishonest or unethical behavior? Lab evidence suggests that it can. In this paper, we document some of the first field evidence of this phenomenon. In this study, individuals were hired as field staff and tasked with distributing subsidized price vouchers...

We measured gender differences in preferences for mate income ex-ante to interaction (“income attraction”) in a field experiment on one of China's largest online dating websites. To rule out unobserved factors correlated with income as the basis of attraction, we randomly assigned income...

We conduct a field experiment in a naturally occurring labor environment and track whether the performance of workers responds to unexpected wage increases. Specifically, we investigate how the timing of wage increases affects efforts. We find that workers’ performance is substantially higher...

We conduct a remittance field experiment among Salvadoran migrants in the metro DC area. Migrants need to decide whether or not to remit funds to a recipient in El Salvador and if so how much. We maintain a (2×2) design in which the remittance budget has a value of $400 or $200, and the...

We experimentally investigate the difference in competitiveness of 3–5 year-old boys and girls in the U.S. 123 children from a preschool are randomly matched into girl–girl, boy–boy, and boy–girl pairs of similar age and participate in a gender-neutral, competitive classroom activity...
