7. Chrissy and Marvin are competitors in a local market and each is trying to decide if it is worthwhile to advertise. If both of them advertise, each will earn a profit of $10,000. If neither of them advertises, each will earn a profit of $20,000. If one advertises and the other doesn't, then the one who advertises will earn a profit of $30,000 and the other will earn $14,000. a. Present the information given above in the form of a payoff matrix indicating the players, their choices and payoffs (profits) from each choice. b. If these two competitors collude what is the best joint strategy that they should agree upon? How much would they each earn in profits? c. Define what is a 'player's' dominant strategy in the context of game theory? What is Chrissy's and Marvin's dominant strategy here? d. Define Nash equilibrium. Identify and label the Nash equilibrium on the payoff matrix from (a). What are the profits earned by each competitor at the equilibrium? e. Comment on the equilibrium price and quantity of an oligopoly market as compared to equilibrium price and quantity of a monopoly and to equilibrium price and quantity of a perfectly competitive market.

The payoff matrix for the game. Find the expected payoff to the row player if the row player uses the maximin pure strategy and the column player uses the minimax pure strategy. (b) Find the expected payoff to the row player if the row player uses the maximin strategy 40% of the time and chooses each of the other two options 30% of the time, while the column player uses the minimax strategy 50% of the time and chooses each of the other columns 25% of the time. (Round your answer to three decimal places) (c) Which of these pairs of strategies is most advantageous to the row player?

Two gas stations, A and B, are locked in a price war. Each player has the option of raising its price (R) or continuing to charge the low price (C). They will choose strategies simultaneously. If both choose C, they will both suffer a loss of $100. If one chooses R and the other chooses C, (i) the one that chooses R loses many of its customers and earns $0, and (ii) the one that chooses C wins many new customers and earns $1000. If they both choose R, the price war ends and they each earn $500. 1. Draw the payoff matrix for this game. B B R C A R (500,500) (0,1000) A C (1,000,0) (-100,-100) 2. What is the optimal strategy? R for A and R for B 3. Does player A have a dominant strategy? Explain. No player A doesn't have a dominant strategy. If player B chooses R, A's best response is to settle on C. If B chooses C, A's best response is to choose C. Since there is no single best response, A does not have a dominant strategy. 4. Does player B have a dominant strategy? Explain. 5. How many Nash equilibria does this game have? 6. What course of action will players A & B choose?
