Game-theoretic centrality is a flexible and sophisticated approach to identify the most important nodes in a network. It builds upon the methods from cooperative game theory and network theory. The key idea is to treat nodes as players in a cooperative game, where the value of each coalition is determined by certain graph-theoretic properties. Using solution concepts from cooperative game theor...

Usually, common pool games are analyzed without taking into account the cooperative features of the game, even when communication and non-binding agreements are involved. Whereas equilibria are inefficient, negotiations may induce some cooperation and may enhance efficiency. In the paper, we propose to use tools of cooperative game theory to advance the understanding of results in dilemma situa...

It is proved that the core in a general setting for cooperative games is equal to the set of subgame perfect equilibria of a noncooperative game of competing contracts. A coalitional deviation in a cooperative game corresponds to, in the noncooperative game, the involved agents’ participation in a contract proposed by a deviating principal. ∗Department of Economics, Iowa State University, 260 H...

PROFESSOR JEAN LEMAIRE: The two models I am going to present originate from game theory. They were devised as illustrations of game theoretical 'models to my operation research students. Game theory has not yet reached a point where it could be practically implemented in insurance companies. The first model I am going to describe is non-cooperative game theory. The second one uses utility theor...

As a kind of intelligent communication technology, the characteristic of dynamic spectrum allocation of cognitive radio provides feasible scheme for sharing with the spectrum resources among the primary user and secondary users, which solves the current spectrum resource scarcity problem. In this paper, we comprehensively explored the cognitive radio spectrum allocation models based on game the...

We consider a symmetric three-stage game played by two regulator-firm hierarchies to capture the scale and technology effects. Each firm produces one good sold on the market. Firms can invest in R&D in order to lower their fixed emission/output ratio and are regulated with costly public funds. Opening markets to international trade leads to both more investment in R&D and production. When the s...

We deal with multi-agent Markov Decision Processes (MDP’s) in which cooperation among players is allowed. We find a cooperative payoff distribution procedure (MDP-CPDP) that distributes in the course of the game the payoff that players would earn in the long run game. We show under which conditions such a MDP-CPDP fulfills a time consistency property, contents greedy players, and strengthen the...

Industry revenue for online games is surging. A unique phenomenon in this market is the significant volume of trade among game users, who exchange real money for virtual goods that do not exist in the real world. The market of virtual goods has two distinctive characteristics: 1) the resold virtual items normally involve no quality loss since the attributes are digitally defined, and 2) the gam...

introduction: when there is no determined value for water (as a public asset) by its trustees and beneficiaries and its allocation method is more dependent on the requirements of water consumers than comparing water affairs benefits with its real value, decision making on which interested group, when and to what extent can use water is a game. this study is aimed to determine sustainable polici...

Among non-oil exports and in trade arena, drug has always been strategic importance and most government especially industrialized countries pay special attention to its production and trade issues. Thus, having a comprehensive view from economic perspective to this section is essential for suggesting intervention. This was a descriptive-analytical and panel study. In this study, gravity model i...
