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...

An active area of research within the social sciences concerns the underlying motivation for sharing scarce resources and engaging in other pro-social actions. We develop a theoretical framework that sheds light on the developmental origins of social preferences by providing mechanisms through...

This paper investigates the relationship between relative earnings and giving in a twostage, real-effort experiment. In the first stage, four players compete in a tournament that determines their earnings. In the second stage, they decide whether they wish to transfer part of their earnings to...

Is the activity of volunteering something that benefits the volunteer as well as the recipient of the volunteer's activities? We analyze this relationship and apply matching estimators to the large-scale British Household Panel Survey (BHPS) data set to estimate the causal impact of volunteering...

Family firms, which are prevalent around the world both for small organizations and large corporations, are usually more performant than other types of firms. This paper draws on altruism and on the theory of incentives contracting to explain why family firms perform better. Assuming that...

For decades, experimental economics has been very interested in behavior that could be characterized as practicing solidarity (although the term is rarely used). Solidarity is a key concept in Catholic Social Teaching. This paper builds a bridge between these two endeavors that, thus far, had...

Today’s record levels of economic inequality are infecting our future as the top 0.01% bequest vast wealth to their descendants. With the death of the Rule Against Perpetuities (RAP), this inequality has the potential to harden social class lines not just for a generation or two but forever....

In a haystack-type representation of a heterogeneous population that is evolving according to a payoff structure of a prisoner's dilemma game, migration is modeled as a process of swapping individuals between heterogeneous groups of constant size after a random allocation fills the haystacks,...

Behind my reciprocation of a friend's gift may lie both instrumental reasons (I expect further future gifts) and 'communicative' reasons (I want to establish or confirm a friendship per se). In a theory of rational individual action, such 'communicative' reasons can be incorporated as an...
