Altruism, understood as the individual disposition to sacrifice personal income to improve someone else’s income can be a rational choice strategy which responds to different motivations, incentives and institutions, in a consistent way with the donor’s optimization logic. In this article we...

This paper reconsiders evidence from experimental common pool resource games from the perspective of a model of payoff sampling. Despite being parameter-free, the model is able to replicate some striking features of the data, including single-peaked frequency distributions, the persistent use of...

Most models of social preferences and bounded rationality that are effective in explaining efficiency-increasing departures from equilibrium behavior cannot easily account for similar deviations when they are efficiency-reducing. We show that the notion of sampling equilibrium, subject to a...
