Using a unique field experiment we show that prompts to leave money to charity during the will-making process substantially increase the probability of making a bequest. Asking if the donor wants to leave money to charity doubles the proportion making a bequest; adding emotional and social cues...

Well-functioning groups enforce social norms that restrain opportunism, but the social structure of a society may encourage or inhibit norm enforcement. Here we study how the exogenous assignment to different positions in an extreme social hierarchy – the caste system – affects...

This paper analyzes how private decisions and public policies are shaped by personal and societal preferences (values), material or other explicit incentives (laws) and social sanctions or rewards (norms). It first examines how honor, stigma and social norms arise from individuals’ behaviors...

Ethical goods are increasingly available in markets for conventional goods giving pro-ethically motivated consumers a convenient option to contribute to public goods. In a previous experiment we explored the behavioural relevance of impure public goods in a within-subject setting and observed...

People cooperate more in one-shot interactions than can be explained by standard textbook preferences. We discuss a set of non-standard preferences that can accommodate such behavior. They are social, in the sense of incorporating the payoffs of other persons; they are also norm-based, in the...

Experimental and observational studies have highlighted the importance of agents being conditionally cooperative when facing a social dilemma. We formalize this mechanism in a theoretical model that portrays a small community having joint access to a common pool resource. The diffusion of norms...

We develop a game-theoretical model of honesty and fairness to study cooperation in social dilemma games with communication. It is based on two key intuitions. First, players suffer a utility cost if they break norms of honesty and fairness, and this cost is highest if most others comply with...

Empirical studies have shown that preferences for redistribution are significantly correlated with expectations of future mobility and the belief that society offers equal opportunities. We add to previous research by investigating the role of individual and social norms on rent seeking. We find...
