Do we praise altruistic acts because they produce social benefits or because they entail a personal sacrifice? Across five studies, we find that people mainly rely on personal cost rather than social benefit when evaluating prosocial actors. This occurs because sacrifice, but not benefit, is...

There is a potential free-rider problem when several siblings consider future provision of care for their elderly parents. Siblings can commit to not providing long- term support by living far away. If location decisions are made by birth order, older siblings may enjoy a first-mover advantage....

Offering incentives to promote charitable giving (for example, to encourage donations to aid victims of natural disasters) is very popular among governments and private organizations. Many companies, for example, match their employees' charitable contributions, hoping that this will foster a...

I derive the marginal value of a public good in multiperson households, measured alternatively by one household member’s willingness to pay (WTP) for the good on behalf of the household, or by the sum of individual WTP values across family members. Households are assumed to allocate their...

This paper is an empirical study of redistributive preferences. Our interest is what motivates net contributors to support redistributive policies. Using instrumental variable estimation and exploiting a particularity of the Spanish labour market we estimate how workers’ declared preferences...

Our paper investigates framing effects in a large-scale public good experiment. We measure indicators of explanations previously proposed in the literature, which when combined with the large sample, enable us to estimate a structural model of framing effects. The model captures potential causal...

The data from experiments with the Voluntary Contributions Mechanism suggest five stylized facts, including the restart effect. To date, no theory has explained all of these facts simultaneously. We merge our Individual Evolutionary Learning model with a variation of heterogenous other-regarding...

We explore the effect of fixed versus dynamic group membership on public good provision. In a novel experimental design, we modify the traditional voluntary contribution mechanism (VCM) by periodically replacing old members of a group with new members over time. Under this dynamic, overlapping...

A long series of laboratory and field experiments, as well as conventional empirical studies, has established that (1) individuals voluntarily provide themselves with public goods at levels exceeding those predicted by the Nash voluntary contributions mechanism, and (2) agents reciprocate...

Explicit economic incentives designed to increase contributions to public goods and to promote other pro-social behavior sometimes are counterproductive or less effective than would be predicted among entirely self-interested individuals. This may occur when incentives adversely affect...
