TLDR
This paper found that participants are significantly more likely to choose social welfare-maximizing actions when matched with an ingroup member when compared to when they are matched with a non-group identity.Abstract:
We present a laboratory experiment that measures the effects of induced group identity on social preferences. We find that when participants are matched with an ingroup member, they show a 47 percent increase in charity concerns and a 93 percent decrease in envy. Likewise, participants are 19 percent more likely to reward an ingroup match for good behavior, but 13 percent less likely to punish an ingroup match for misbehavior. Furthermore, participants are significantly more likely to choose social-welfare-maximizing actions when matched with an ingroup member. All results are consistent with the hypothesis that participants are more altruistic toward an ingroup match. (read more

Group Membership, Competition, and Altruistic versus Antisocial Punishment: Evidence from Randomly Assigned Army Groups
Lorenz Goette,Lorenz Goette,Lorenz Goette,David Huffman,David Huffman,Stephan Meier,Stephan Meier,Stephan Meier,Sutter Matthias +8 more
TL;DR: The authors investigated how group boundaries, and the economic environment surrounding groups, affect altruistic cooperation and punishment behavior and found that without competition between groups, individuals are more prone to cooperate altruistically in a prisoner's dilemma game with in-group as opposed to out-group members.

Social distance in a virtual world experiment
TL;DR: In this paper, a quasi-field experiment in a virtual world environment was conducted to investigate the impact of social distance on economic choices, and they found that the proposers are more likely to select the socially closer responders despite the lower rate of investment returns, and the latter reciprocate by returning a higher proportion than the socially distant responders.

The effect of social fragmentation on public good provision : an experimental study
TL;DR: This paper study the role of social identity in determining the impact of social fragmentation on public good provision using laboratory experiments, and find that as long as there is some degree of social heterogeneity, increasing it leads to lower public-good provision by majority group members.

Behavior in Group Contests: A Review of Experimental Research
TL;DR: The authors showed that the intensity of competition between groups and the amount of freeriding within groups depend on the group size, sharing rule, group impact function, contest success function, and heterogeneity of players.

Group identity and leading-by-example

Controlling the false discovery rate: a practical and powerful approach to multiple testing
Yoav Benjamini,Yosef Hochberg +1 more
TL;DR: In this paper, a different approach to problems of multiple significance testing is presented, which calls for controlling the expected proportion of falsely rejected hypotheses -the false discovery rate, which is equivalent to the FWER when all hypotheses are true but is smaller otherwise.

The social identity theory of intergroup behavior
Henri Tajfel,John C. Turner +1 more
TL;DR: A theory of intergroup conflict and some preliminary data relating to the theory is presented in this article. But the analysis is limited to the case where the salient dimensions of the intergroup differentiation are those involving scarce resources.

A theory of fairness, competition and cooperation

TL;DR: This paper showed that if some people care about equity, the puzzles can be resolved and that the economic environment determines whether the fair types or the selesh types dominate equilibrium behavior in cooperative games.
