In Uganda, consumers are likely to buy cell phones from either MTN Rwanda Ltd or Tigo Rwanda Ltd because the two firms have a combined market share that approaches 90 percent. These companies can either set a high price or set a low price. The payoff matrix shows how each company's hypothetical economic profit depends on its price and its rival's price. The hypothetical profits are in Ugandan shillings, and price-fixing cartels are illegal in Uganda Is there a pure-strategy Nash equilibrium? If so, what is it? A. The pure-strategy Nash equilibrium occurs where both firms set high prices, as neither firm can increase its profits by unilaterally changing its strategy. B. There is no pure-strategy Nash equilibrium as at least one firm can increase its profits by unilaterally changing its strategy in each possible outcome OC. The pure-strategy Nash equilibrium occurs where MTN sets a high price and Tigo sets a low price, as neither firm can increase its profits by unilaterally changing its strategy. D. The pure-strategy Nash equilibrium occurs where both firms set low prices, as neither firm can increase its profits by unilaterally changing its strategy. Is there a mixed-strategy Nash equilibrium? If so, what is it? O A. The mixed-strategy Nash equilibrium occurs when Tigo chooses a high price with a probability of 0.80 and MTN chooses a high price with a probability of 0.25. B. The mixed-strategy Nash equilibrium occurs when Tigo chooses a high price with a probability of 0.25 and MTN chooses a high price with a probability of 0.80. OC. There is no mixed-strategy Nash equilibrium, as any mixed strategy that involves setting a low price at least part of the time will have a profit lower than any pure-strategy. OD. The mixed-strategy Nash equilibrium occurs when Tigo chooses a high price with a probability of 0.15 and MTN chooses a high price with a probability of 0.70.
