3. Reuben and Simeon are duopolists producing jeans in a differentiated goods market. Themarket demand for Reuben's jeans is y₁ = 75 − P₁ + P2, while the market demand for11Simeon's jeans is y₂ = 75 − P2 + ₂P₁. Reuben's cost function is C₁(y₁) = 75y₁ whileSimeon's cost function is C₂ (y₂) = 75y2.a) Calculate the Bertrand equilibrium in this market. Indicate each firm's price, outputlevel, and profits.

The payoff matrix depicts potential payoffs in a non-sequential, non-repeating game. Blue numbers are for Player 1 and red numbers are for player 2. (This exact payoff matrix appears in 3 other questions on this exam.). The cooperative (collusive) equilibrium is: Player 1 (70,80) 0000 (30,20) (40,40) (10,90) Strategy C Strategy D Player 2 Strategy A 40, 40 10,90 Strategy B 30, 20 70, 80

Question 2 (Choices Involving Strategy): Suppose there are two competing Gyms in a local town. Each gym is individually owned and has three pricing levels to choose from: Low, Medium and High (PL,PM, and PH). Consider the table below as the outcomes for each combination of strategies (they are yearly profits in the thousands). Can you predict the outcome using ONLY iteratively dominated strategies? Why or why not? Find the Nash Equilibrium(a) using best responses. Is this the best outcome? Now, suppose that there was a sudden increase in the cost of equipment that meant the low price was no longer viable, and both choosing the medium price level meant only 50 (thousand) profit for each gym. Nothing else changes. What is the pure and mixed strategy Nash equilibrium of this new game? Gym 1 is on the left and Gym 2 is on the top. The first number inside every box is Gym 1's profit and the second (after the comma) is Gym 2's profit. (10 Marks) PL PMPH PL 125, 125 200, 75 375,50 PM 75, 250…
