Nash equilibria. PARETO OPTIMUM/EQUILIBIRUM/EFFICIENT The idea of pareto optimum runs through all aspects of economics, for example, comparing different tax rules, and not just in game theory. It gained currency as a test to be applied in selecting economic policy as a result of a contradiction in the theory of the market deriving from the philosophy of utilitarianism. Utilitarianism could be construed as a justification for the oppression of the individual in the name of the greater good of

involves the study of quantity as it relates to addition, subtraction, multiplication, and division. Mathematicians refer to the more advanced term of number theory. Antoine-Augustin Cournot and Joseph Louis Francois Bertrand’s influence on mathematics lay the foundation of the economic effect of the application method on economic theory and analysis of how it will affect others. Each allows individuals to form a meaningful understanding of the complex expressions in various languages. Cournot

usually analysed in game theory by means of a non-zero-sum game called the "Prisoner's Dilemma" (Axelrod, 1984). The two players in the game can choose between two moves, either "cooperate" or "defect". The idea is that each player gains when both cooperate, but if only one of them cooperates, the other one, who defects, will gain more. If both defect, both lose (or gain very little) but not as much as the "cheated" cooperator whose cooperation is not returned. The whole game situation and its different

results. In this experiment, rational answer would be all players playing 0. This is because of the following reasoning: All players have the same information, and are assumed to be equally rational. This is referred to as Nash equilibrium in Game theory. The experiment shows an easy way to test how theoretical assumptions in a lecture. The results represent pretty much the theoretical hypothesis that we devote our intelligences to anticipating what average opinion expects the average opinion to

That is, if the entrant has come, would it make sense for the monopolist to charge a low price? Explain.

The prisoners’ dilemma is the best-known game of strategy in social science. It helps us understand what governs the balance between cooperation and competition in business, in politics, and in social settings. In the traditional version of the game, the police have arrested two suspects and are interrogating them in separate rooms. Each can either confess, thereby implicating the other, or keep silent. No matter what the other suspect does, each can improve his own position by confessing. If the
