The Core of a Strategic Game
نویسنده
چکیده
This paper introduces and studies the γ-core of a general strategic game. It shows that a prominent class of games admit nonempty γ-cores. It also shows that the γ-core payoff vectors (a cooperative solution concept) can be supported as equilibrium outcomes of a non-cooperative game and the grand coalition is the unique equilibrium outcome if and only if the γ-core is nonempty. As an application of this result, it shows that the γ-core of an oligopoly game is nonempty and, therefore, the oligopoly may become a monopoly unless prevented by law. JEL classification numbers: C71-73, D43, L13

Dynamic system of strategic games
Maybe an event can't be modeled completely through one game but there is more chance with several games. With emphasis on players' rationality, we present new properties of strategic games, which result in production of other games. Here, a new attitude to modeling will be presented in game theory as dynamic system of strategic games and its some applications such as analysis of the clash betwe...
متن کاملThe competitive advantages analysis of pharmaceutical industry strategic behaviors by game theory
Game theory is the study of mathematical models and cooperation between intelligent rational decision-makers. This paper provides a flexible model to calculate pay-off matrix based on several importance factors. This model is adapted by cooperative game and developed for some competitive advantages sections in pharmaceutical industry. An optimum solution is derived by considering Nash equilibri...

متن کاملAnalysis of the Evolutionary Game Theory in Agent-Based Computational Systems: OPEC Oil-Producing Countries
This study suggests a new method for analysing the behavioral economics issues in the framework of game theory. In this context, bounded rational agents interact with one another in a strategic manner. Therefore, conventional economic modeling techniques are unable to explaine this kind of interactions. In this regard, evolutionary game theory and agent-based modeling are known as the most suit...
متن کاملDistribution Design of Two Rival Decenteralized Supply Chains: a Two-person Nonzero Sum Game Theory Approach
We consider competition between two decentralized supply chains network under demand uncertainty. Each chain consists of one risk-averse manufacturer and a group of risk-averse retailers. These two chains present substitutable products to the geographical dispensed markets. The markets’ demands are contingent upon prices, service levels, and advertising efforts of two supply chains. We formulat...
متن کاملA review on symmetric games: theory, comparison and applications
Game theory models decision makers' behaviors in strategic situations. Since the structures of games are different, behavior and preferences of the players are different in various types of game. This paper reviews various situations of games. Here, characteristics of some common games are discussed and compared. Specifically, we focus on a group of games called symmetric games including Prison...
