Even though human social behavior has received considerable scientific attention in the last decades, its cognitive underpinnings are still poorly understood. Applying a dual-process framework to the study of social preferences, we show in two studies that individuals with a more...

Using a gift exchange experiment, we show that the ability of reciprocity to overcome incentive problems inherent in principal-agent settings is greatly reduced when the agent’s effort is distorted by random shocks and transmitted imperfectly to the principal. Specifically, we find that gift...

We compare the determinants of individual giving between two countries, Spain and the US, which differ in their redistribution policies and their beliefs over the causes of poverty. By varying the information about the determinants of income, we find that, although overall giving is similar in...

Buser (2012) reports an association between the second-to-fourth digit ratio, a biomarker of the exposure to prenatal sex hormones, and behavior in several classic experimental games designed to elicit prosocial attitudes. His subjects self-report whether they have shorter, equal, or larger ring...

Using a large (n=543) multi-ethnic sample of laboratory subjects, we systematically investigate the link between the digit ratio (the ratio of the length of the index finger to the length of the ring finger, also called 2D:4D ratio) and two measures of individual risk taking: (i) risk...

We experimentally investigate the effect of social identification and information feedback on individual behavior in contests. Identifying subjects through photo display decreases efforts. Providing information feedback about others’ effort does not affect the aggregate effort levels but it...

We design an experiment to explore the impact of earned entitlements on the frequency and intensity of conflicts in a two-stage bargaining and conflict game with side-payments. In this game, residents (Proposers) make side-payment offers and contestants (Responders) decide whether to accept the...

This study examines behavior of subjects in simultaneous and sequential multi-battle contests. In simultaneous contests, subjects make positive bids in each battle 80% of the time and bids fall within the predicted boundaries. However, 35% of the time subjects make positive bids in only two,...

Many economic interactions are characterized by “all or nothing” action spaces that may limit a demonstrable index of trust and, therefore, the propensity to reciprocate. In two experimental trust games, the action space governing investments was manipulated to examine the effects on...

Motivated by problems of coordination failure observed in weak-link games, we experimentally investigate behavioral spillovers for minimum- and median-effort coordination games. Subjects play these coordination games simultaneously and sequentially. The results show that successful coordination...
