Assume that two companies (A and B) are duopolists who produce identical products. Demand for the products is given by the following linear demand function: P=200 QA QB where Q A and Q 3 are the quantities sold by the respective rms and p is the selling price. The total cost lnctions for the two companies are: TCA = 1500 + 5542,. + (.23 T0,; = 1200 + 2003 + (25 Assume that the rms act independently as in the Cournot model (i.e., each rm assumes that the other rm's output will not change). Based upon this information, a. Determine the long-run equilibrium output and selling price for each rm. b. Determine Firm A, Firm B, and total industry prots at the equilibrium solution found in (a)
