Recent research has highlighted the role of prosocial personality traits-agreeableness and honesty-humility-in egalitarian distributions of wealth in the dictator game. Expanding on these findings, we ran two studies to examine individual differences in two other forms of prosociality-generosity and reciprocity-with respect to two major models of personality, the Big Five and the HEXACO. Partic...

Two experiments tested the idea that economic transactions among friends are influenced by a norm of generosity. Whereas a fairness norm ought to promote agreement in offers between buyers and sellers, a generosity norm should promote altruistic disagreements caused by sellers offering lower prices than buyers—a reversal of the well-known endowment effect. Supporting the present account, in bot...

This paper estimates the correlation between the generosity of parents and the generosity of their adult children using regression models of adult children's charitable giving. New charitable giving data are collected in the Panel Study of Income Dynamics and used to estimate the regression models. The regression models are estimated using a wide variety of techniques and specification tests, a...

Research has demonstrated that sharing with others is rewarding, suggesting a proximal mechanism of humans' extraordinary tendency to engage in prosocial behavior. The current study explored the cognitive basis of the relation between generosity and happiness early in ontogeny. We demonstrate that preschool children understand the relation between generosity and happiness. Moreover, our results...

Development economists have superseded any necessity of using Arrow’s methodological individualism (MI) in focusing on cross-cultural, cross-national, or developmental economics. This study examines whether analysis of cross-cultural economic models might include a concept of economic generosity as a type of economic structuration that deviates from MI principles and is closer to what economist...

Bruno Poizat is associated, among other things, with broadening the scope of the theory of groups of finite Morley rank to the level of stable groups [P87], in keeping with the general trend of the development of model theory from Morley to Shelah. But this has not prevented him from taking an active interest in such aspects of the theory as are associated more particularly with the case of fin...

Despite its centrality to contemporary inequality, working poverty is often popularly discussed but rarely studied by sociologists. Using the Luxembourg Income Study (2009), we analyze whether an individual is working poor across 18 affluent democracies circa 2000. We demonstrate that working poverty does not simply mirror overall poverty and that there is greater cross-national variation in wo...
