Emergence of cooperation in public goods games.
Evolution of cooperation has been a major issue in evolutionary biology. Cooperation is observed not only in dyadic interactions, but also in social interactions involving more than two individuals. It has been argued that direct reciprocity cannot explain the emergence of cooperation in large groups because the basin of attraction for the 'cooperative' equilibrium state shrinks rapidly as the ...
متن کاملCooperation and Punishment in Public Goods Experiments
Casual evidence as well as daily experience suggest that many people have a strong aversion against being the "sucker" in social dilemma situations. As a consequence, those who cooperate may be willing to punish free-riding, even if this is costly for them and even if they cannot expect future benefits from their punishment activities. A main purpose of this paper is to show experimentally that...
متن کاملEcological public goods games: cooperation and bifurcation.
The Public Goods Game is one of the most popular models for studying the origin and maintenance of cooperation. In its simplest form, this evolutionary game has two regimes: defection goes to fixation if the multiplication factor r is smaller than the interaction group size N, whereas cooperation goes to fixation if the multiplication factor r is larger than the interaction group size N. Hauert...
متن کاملGender Beliefs and Cooperation in a Public Goods Game
This paper identifies gender beliefs in a public goods game and studies their impact on cooperation. On average, the beliefs of men, but not those of women, depend significantly on the group gender composition, with men expecting groups to be more cooperative when more females are present in the group. Gender beliefs of women are not absent, however, but show more variance than those of men. Th...
متن کاملGroup-Level Selection Increases Cooperation in the Public Goods Game
When groups compete for resources, some groups will be more successful than others, forcing out less successful groups. Group-level selection is the most extreme form of group competition, where the weaker group ceases to exist, becoming extinct. We implement group-level selection in a controlled laboratory experiment in order to study its impact on human cooperation. The experiment uses variat...
