In today’s increasingly interconnected world, deciding with whom and at what level to cooperate becomes a matter of increasing importance as societies become more globalized and large-scale cooperation becomes a viable means of addressing global issues. This tension can play out via...

Intergroup conflicts generally involve conflicts of interests within the competing groups as well. This paper outlines a taxonomy of games, called team games, which incorporate the intragroup and intergroup levels of conflict. Its aims are to provide a coherent framework for analyzing the...

Two experiments compared the Centipede game played either by 2 individuals or by 2 (3-person) groups. The 2 competitors alternate in deciding whether to take the larger portion of an increasing (or constant) pile of money, and as soon as one “takes” the game ends. Assuming that both sides...

We studied conflict resolution in two types of intergroup conflicts modeled as team games, a game of Assurance where the groups’ incentive to compete is purely fear, and a game of Chicken where the groups’ incentive to compete is purely greed. The games were operationalized as competitions...

Explaining human cooperation in large groups of non-kin is a major challenge to both rational choice theory and the theory of evolution. Recent research suggests that group cooperation can be explained assuming that cooperators can punish non-cooperators or cheaters. The experimental evidence...

Consider a parliamentary committee with an equal number of coalition and opposition members. The opposition needs a strict majority to pass a motion, whereas for the coalition a tie is sufficient to block the motion and maintain the status quo. Passing or blocking the motion is a public good...

In this paper I classify situations of interdependent decision-making, or games based on the type of decision-makers, or players involved. The classification builds on a distinction between three basic types of decision-making agents: individuals, cooperative or unitary groups -- groups whose...

Intergroup conflicts are characterized by conflicts of interests within the competing groups as well. The intragroup conflict stems from a basic fact: while all group members are better off if they all cooperate in competing against the outgroup, each individual group member is better off...

What motivates individual self-sacrificial behavior in intergroup conflicts? Is it the altruistic desire to help the ingroup or the aggressive drive to hurt the outgroup? This paper introduces a new game paradigm, the Intergroup Prisoner’s Dilemma – Maximizing Difference (IPD-MD) game,...

We conducted an experimental study of price competition in a duopolistic market. The market was operationalized as a repeated game between two “teams” with one, two, or three players in each team. Each player simultaneously demanded a price, and the team whose total asking price was smaller...
