Using experiments, we examine whether the decision to trust a stranger in a one-shot interaction is equivalent to taking a risky bet, or if a trust decision entails an additional risk premium to balance the costs of trust betrayal. We compare a binary-choice Trust game with a structurally identical, binary-choice Risky Dictator game with good or bad(More)
Recent policy initiatives offer cash payments to children (and often their families) to induce better health and educational choices. These policies implicitly assume that children are especially impatient (i.e., have high discount rates); however, little is known about the nature of children's patience, how it varies across children, and whether children(More)

Anthropologists have long noted that one of the primary functions of religion is to promote group solidarity, and most have recognized ritual as the mechanism through which this solidarity is achieved. Guided by Durkheim (1995 [1912]), who was among the first to appreciate the unifying nature of religious ritual, functionalists have explored how ritual(More)
The in-group-out-group bias is among the most well documented and widely observed phenomenon in the social sciences. Despite its role in hiring decisions and job discrimination, negotiations, and conflict and competition between groups, economists have heretofore ignored the in-group-out-group bias. We question the universality of the bias by designing(More)
Many important economic decisions involve financial risk, and there is substantial evidence that women tend to be more risk averse than men. We explore a potential biological basis of the variation in risk-taking within and between men and women using an emerging measure of prenatal androgrens, the ratio between the length of the second and fourth digits(More)
To See Is To Believe: Common Expectations in Experimental Asset Markets We challenge the recent claim that mispricing in the experimental asset markets introduced by Smith, Suchanek, and Williams (1988) is merely an artefact of confusion over declining fundamental value, and can be eliminated through appropriate training. We instead propose that when(More)
We present evidence from a natural field experiment involving nearly 100,000 individuals on the effects of offering economic incentives for blood donations. Subjects who were offered economic rewards to donate blood were more likely to donate, and more so the higher the value of the rewards. They were also more likely to attract others to donate, spatially(More)
Although discrimination remains prevalent, the reasons for its occurrence are still hotly debated. To disentangle vying explanations, researchers have begun using laboratory experiments. However, this research has not allowed, or studied, the effects of selection. In this paper, we examine discrimination in a Trust game where subjects can and cannot select(More)
Is There Selection Bias in Laboratory Experiments? The Case of Social and Risk Preferences Laboratory experiments are frequently used to examine the nature of individual preferences and inform economic theory. However, it is unknown whether the preferences of volunteer participants are representative of the population from which the participants are drawn(More)
Will There Be Blood? Incentives and Substitution Effects in Pro-social Behavior We examine how economic incentives affect pro-social behavior through the analysis of a unique dataset with information on more than 14,000 American Red Cross blood drives. Our findings are consistent with blood donors responding to incentives in a “standard” way; offering(More)
