Game Theory and Strategic Interaction

Game Theory primarily analyzes how individuals make decisions in strategic situations where their choices affect the outcomes of others.

Nash Equilibrium is a central concept in Game Theory, describing a situation where no player can improve their outcome by unilaterally changing their strategy, assuming other players' strategies remain unchanged.

In the Prisoner's Dilemma, the dominant strategy for each player is to defect, regardless of the other player's strategy. This leads to a suboptimal outcome for both players, known as the Prisoner's Dilemma.

A Zero-Sum Game is a type of game where the total sum of payoffs for all players is constant. This means that one player's gain is necessarily another player's loss.

In a game with complete information, it is assumed that all players have full knowledge of all possible strategies and the associated payoffs for each strategy.

Tit-for-Tat is a strategy in which a player cooperates on the first move and then responds to the opponent's previous move: cooperation is met with cooperation, and defection is met with defection.

In a game with incomplete information, it is assumed that players do not have full knowledge of all possible strategies and the associated payoffs for each strategy.

The Prisoner's Dilemma is an example of a non-cooperative game, where players have conflicting interests and no formal agreements or communication can be made.

In a game with perfect information, it is assumed that all players have full knowledge of all possible strategies and the associated payoffs for each strategy.

Oligopoly is an example of a cooperative game, where firms in an industry can potentially collude or cooperate to maximize their collective profits.

In a game with imperfect information, it is assumed that players do not have full knowledge of all possible strategies and the associated payoffs for each strategy.

Bertrand Competition is an example of a zero-sum game, where firms in an industry compete on price, and the total market share remains constant.

In a game with complete information, it is assumed that all players have full knowledge of all possible strategies and the associated payoffs for each strategy.

Cournot Competition is an example of a non-zero-sum game, where firms in an industry compete on quantity, and the total market share can expand or contract.

In a game with imperfect information, it is assumed that players do not have full knowledge of all possible strategies and the associated payoffs for each strategy.
