Reciprocity serves as an explanation for why participants cooperate in dyads, but fails to account for larger groups. Evolutionary theories of indirect reciprocity and costly signaling may be useful to explain large-scale cooperation. When people can selectively choose partners to play games with, it pays to develop a cooperative reputation ...
Collaboration (from Latin com-"with" + laborare "to labor", "to work") is the process of two or more people, entities or organizations working together to complete a task or achieve a goal. [1] Collaboration is similar to cooperation. The form of leadership can be social within a decentralized and egalitarian group. [2]
The prisoner's dilemma is a game theory thought experiment involving two rational agents, each of whom can either cooperate for mutual benefit or betray their partner ("defect") for individual gain. The dilemma arises from the fact that while defecting is rational for each agent, cooperation yields a higher payoff for each.
People form families, tribes, cities and nations. Atoms cooperate in a simple way, by combining to make up molecules. Understanding the mechanisms that create cooperating agents in a system is one of the most important and least well understood phenomena in nature, though there has not been a lack of effort.

A payoff maximizing third party would choose not to punish, and a similarly rational allocator would choose to keep the entire sum for himself. However, experimental results show that a majority of third parties punish allocations less than 50% [ 12 ] In the prisoner's dilemma with third party punishment, two of the participants play a prisoner ...
Cooperative game theory is a branch of game theory that deals with the study of games where players can form coalitions, cooperate with one another, and make binding agreements. The theory offers mathematical methods for analysing scenarios in which two or more players are required to make choices that will affect other players wellbeing.
The lessons described above apply in environments that support cooperation, but whether cooperation is supported at all, depends crucially on the probability (called ω [omega]) that the players will meet again, [15] also called the discount parameter or, figuratively, the shadow of the future.
Tit for tat is very different from grim trigger, in that it is forgiving in nature, as it immediately produces cooperation, should the competitor choose to cooperate. Grim trigger on the other hand is the most unforgiving strategy, in the sense even a single defect would the make the player playing using grim trigger defect for the remainder of ...
