In order to explore the evolution of mutually beneficial transactions in large societies, this experimental study gathered data on the way people in societies of different subsistence types played games simulating interactions with anonymous others. The degree of fairness displayed by different players was correlated with measures of large-scale institutions, such as a market or world religion, that were present in a player’s society. Results suggest that “modern prosociality is not solely the product of an innate psychology, but also reflects norms and institutions that have emerged over the course of human history” (1480).

This study examines costly punishment behavior across cultures. Authors conducted economic games in a variety of societies and found that costly punishment behavior occurs to varied degrees across cultures. Results also suggest that altruistic behavior is associated with costly punishment behavior.

This article presents the results of economic behavior experiments conducted on members of 15 small scale societies. Although three different economic experiments were conducted, findings focus on the results of the "Ultimatum Game." The authors found that no society adhered to behavior predicted by the "selfishness axiom" which suggests that individuals will behave in a way that maximizes their own gain. Authors also discuss possible predictors of behavioral variation within and between groups.

Observing that rates of polygynous marriage tend to increase with wealth difference, the authors of this paper attempt to understand why monogamous marriage has flourished in Europe and other parts of the world even as wealth differences have expanded. The authors theorize that monogamous marriage promotes the success of the groups that employ the practice by suppressing intra-group competition and that this is what has happened in Europe. Subsequently, the authors test hypotheses that are implicated in this theory.
