Question

One – period game

If there are two companies who control the market and compete on price what would the payoff matrix look like for the prisoner’s dilemma? DRAW THE MATRIX (Company A on top, B on the side, when both go high the profit $36 for A and $36 for B when both go low the profit is $18 for A and $18 for B, When A goes high and B goes low the profit is $48 for B and $16 for A and when A goes low and B goes high the profit is $16 for B and $48 for A and) What will they end up doing? What does it mean to have a dominant strategy in the prisoner’s dilemma? What is a Nash-equilibrium? Is the solution for this problem Nash?Would you expect the same result if this was a “repeated” game? Explain.

Answer 1

In case the game is repeated for n th period the equilibrium will be same. This is because, by backward induction given the strategy of the other player in the previous period it will be best for each player to play low. that is if in nth periof a player has to decide which strategy to play it will look back at n-1 th period. In this period the other player has chosen "low" given this the best move will be to choose "low" as well. then the equilibrium will remain the same for infinitely repeated game.
