Hello! I see as explaining  the game theory that the profit reported makes the players make a choice. However, if I am creating for a test a matrix, how do I get the correct number that will allow me to make an interpretation of their strategies?

Dominant strategy is when you choose the same regardless of what the other player chooses!

Oligopoly & Game Theory

  • In an oligopoly, there are a few firms that dominate the market.
  • Out of all market structures, collusion works best in an oligopoly as there are so few firms.
  • Game Theory is most easily understand in a two-player game with two possible choices.
  • In a prisoner’s dilemma, there exists a dominant strategy that, when played, will lead to the Nash Equilibrium.
  • Even though the best group outcome is to cooperate, individual self-interest is such that in a prisoner’s dilemma, each person benefits from not cooperating given the choice of his or her opponent.
  • Other game theory models exist such as chicken, one dominant strategy/no dominant strategy.
