Introduction
Game theory, in this essay, means the study of strategies adopted by rational decision-makers of economic agents in specific situations, analyzing outcomes of mathematical models of conflict and cooperation (Myerson, 1991). Its basic elements include players, actions, information, strategies, payoffs, outcome and equilibrium, among which, players, strategies and payoffs are the most essential; actions and outcome are called as rules of the game (Rasmusen, 2000). The objective of the model is to establish equilibrium with the use of rules of the games. Nash equilibrium, an important terminology in Game theory, is the situation when two or more players are involved in the game, and each player is supposed to know other players’ equilibrium strategies; players will get nothing just by changing their own strategy (Gibbons, 1992: p.8). Entry deterrence game, as a typical example in industrial economics, can be seen in the competitive markets in real society will be regarded as an object to be discussed In the subsection, firstly, entry deterrence game will be put into four classical types of game theories for analyzing and different strategies for the players in the games will be work out by using the given models; then the use of game theory in real entry deterrence will be slightly discussed. Model Analysis

The first situation is the entry deterrence under the static games of complete information. Suppose that there is already a monopolist company B as the incumbent in a specific industry; another company A as the entrant wants to enter this market. All the information in this market is open to A and B. B, in order to keep its profit, will try to prevent A from entering the market. There are two strategies for A to choose---to enter or to stay out; if entry occurs, there will be two choices for B---to collude or to fight. Suppose the entry costs are 10; duopoly profit---100 will be split evenly to A and B if B collude when A enters. Table 1...

...Consider a firm that is contemplating entry into a new market. What
contribution, if any, can gametheory make to the analysis of the economic
viability of such a strategy? Refer to the critical time line, reaction functions
and the Nash premise in your reply.

The foundations of negotiation theory are decision analysis, behavioral decision making, gametheory, and negotiation analysis. Another classification of theories distinguishes between Structural Analysis, Strategic Analysis, Process Analysis, Integrative Analysis and behavioral analysis of negotiations.

...GAMESTHEORY
In gametheory, Nash equilibrium (named after John Forbes Nash, who proposed it) is a solution concept of a game involving two or more players, in which each player is assumed to know the equilibrium strategies of the other players, and no player has anything to gain by changing only his own strategy unilaterally. If each player has chosen a strategy and no player can benefit by changing his or her strategy...

...It is called the Beauty contest Experiment because it was based on a theory John Maynard Keynes proposed on the relationship of the stock market with beauty contests conducted in newspapers of his time. In this report I will examine the logic behind choosing the best response strategy in theory and compare it with the actual results of the experiment conducted. From the comparison I will provide justification for why the theory is different from...

Preface
Since GameTheory is a tool used to analyze strategic behavior by taking into consideration how participants expect other to behave I thought about an everyday example in my life. I wanted to analyze my job at the bar and take into account some independent parties that compete with me. Since it’s not my choice who my boss will hire or fire I was interested in...
