This paper addresses the problem of determining when coordination is beneficial. I describe a negative externality game containing a “worsening parameter and develop a framework linearizing this parameter for tractable examination. The worsening parameter can be classified according to “own effect” – changing the marginal utility of a players own action, “opponent effect” – altering the margina...

The cooperative game of global temperature lacks automaticity and emotional jamming. To solve this issue, an agent-based modelling method is developed based on Milinski’s noncooperative game experiments. In addition, genetic algorithm is used to improve the investment strategy of each agent. Simulations are carried out by designing different coding schemes, mutation schemes, and fitness functio...

We propose a semi-cooperative game theoretic approach to check whether a given coalition is stable in a Bayesian game with independent private values. The ex ante expected utilities of coalitions, at an incentive compatible (noncooperative) coalitional equilibrium, describe a (cooperative) partition form game. A coalition is core-stable if the core of a suitable characteristic function, derived...

Concepts from cooperative game theory have been applied to a wide range of economic problems with great success. The core equivalence and value equivalence theorems are outstanding examples of the fruitful synthesis of game theory and equilibrium analysis. These (and other results from cooperative game theory) have provided insight into market outcomes by investigating the problems in the absen...

In this paper, resource allocation models for cognitive radio networks (CRN) using game theory are presented. The study includes the concept of cognitive radio (CR) networks, cooperative and non-cooperative game theory, and modeling of strategic interaction process for CR enabled secondary users. The prime objective of the present study is to compare existing game models for CR networks in term...

We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff vectors satisfying this condition. The additional requirement of transfer rate equilibrium refines the core concept and allows the selection of specif...

We use the self-tuning Experience Weighted Attraction model with repeated-game strategies as a computer testbed to examine the relative frequency, speed of convergence and progression of a set of repeated-game strategies in four symmetric 2 × 2 games: Prisoner's Dilemma, Battle of the Sexes, Stag-Hunt, and Chicken. In the Prisoner's Dilemma game, we find that the strategy with the most occurren...

Roughly speaking, Game Theory deals with analysing conflict and cooperation situations in which two or more rational and intelligent agents are involved. There are many real and theoretical situations which can be examined from the point of view of Game Theory. Therefore it is not difficult to find in the literature a rich variety of applications of Game Theory to many and very diverse fields o...

Computer games have become increasingly cooperative social activities that are often being played with several collocated gamers, frequently in front of spectators who react and participate in the gameplay experience. Physical controllers are enriching the gaming interface by allowing players to use their bodies to control the game. We highlight another gameplay theme: in-game authorship of con...

The paper is devoted to two real problems that generate a cooperative game model with a so-called k-convex characteristic function when certain conditions are fulfilled. Both a bankruptcy problem and an information trading problem are modelled as a cooperative game by constructing the corresponding bankruptcy game as well as the information market game. Firstly, it is established that the bankr...
