We model the two-Wrm alliance as an iterated prisoners’ dilemma game with an exit option and test several theoretical predictions over two experimental studies. A new major eVect on alliance performance arises by including the exit option (i.e., the option to end the alliance and receive a Wxed payoV that is less than the payoV for mutual cooperation but greater than the payoV for mutual defect...

This article describes a particular way developed by employees to respond to the constraints of a very restrictive manufacturing plant: the mutual cooperation. Facing a very strict organizational context, the production workers can only rely on themselves to cope with the constraints of work. In this context, a complex system of strategies is deployed, resulting in a work environment governed b...

The Intergroup Prisoner’s Dilemma with Intragroup Power Dynamics (IPD^2) is a new game paradigm for studying human behavior in conflict situations. IPD^2 adds the concept of intragroup power to an intergroup version of the standard Repeated Prisoner’s Dilemma game. We conducted a laboratory study in which individual human participants played the game against computer strategies of various compl...

It is popular that two players face with each other repeatedly in different phases [1]. Workers usually have relationship with their colleagues not only at work but also privately. Governments make negotiations on agricultural trade in addition to industrial trade. A hotel chain competes with the rival in various areas. Do these situations facilitate cooperation? What kind of decision makings s...

An open problem in evolutionary game dynamics is to understand the effect of peer pressure on cooperation in a quantitative manner. Peer pressure can be modeled by punishment, which has been proved to be an effective mechanism to sustain cooperation among selfish individuals. We investigate a symmetric punishment strategy, in which an individual will punish each neighbor if their strategies are...

Cooperative behavior can be observed widely in our society. An important aspect of cooperation is that people can maintain mutual cooperation even if they are faced with social dilemma, which means the situation that people fail to cooperate although entire cooperation gives better payoff to everyone. Several mechanisms are pointed out to be important to overcome the social dilemma, and recipro...

We study the evolution of cooperation in the evolutionary spatial prisoner's dilemma game (PDG) and snowdrift game (SG), within which a fraction α of the payoffs of each player gained from direct game interactions is shared equally by the immediate neighbors. The magnitude of the parameter α therefore characterizes the degree of the relatedness among the neighboring players. By means of extensi...

Concurrent Engineering supports the cooperation of teams coming from different phases of the engineering process. Mutual understanding between these crossfunctional teams is essential for successful cooperation. One obstacle for mutual understanding is the use of different languages, notations, and representations within different phases of the engineering process. Fine-grained relationships be...

The Nash equilibrium, the main solution concept in analytical game theory, cannot make precise predictions about the outcome of repeated mixed-motive games. Nor can it tell us much about the dynamics by which a population of players moves from one equilibrium to another. These limitations, along with concerns about the cognitive demands of forward-looking rationality, have motivated efforts to ...

In this paper, a novel technique known as Cooperative Communication in MIMO has been incorporated. This technique allows single antenna mobiles to have the benefits of MIMO systems. Numerical analysis and mathematical modeling is done for SISO with no cooperation, MIMO with no cooperation and MIMO with cooperation or Cooperative MIMO. Expressions for SNR, Outage probability and capacity over a ...
