Maggie's utility function is and her income is $5000. Then her MRS at generic bundle (x1, x2) is 50-0.25x1. Commodity 2 is a composite good, and hence its price is unity. Commodity 1 is the good that is a referred to in question 1, for which X is the total market demand. We let P denote the price of commodity 1. Consumer welfare calculation, pretend that maggie is the only consumer in the market. Therefore, the market demand function for commodity 1 is X = 200 - 4pP, where X represents x1.
1. Continue to assume that fixed costs are zero. Calculate Maggie's utility when the industry is competitive, and when the market is served by a monopoly (or a cartel).
2. Now we assume (realistically) that fixed costs are $800. Would commodity 1 be provided at all by a competitive industry? Explain your answer. If commodity 1is provided by a competitive industry what would be maggie's resulting utility?
3. Would commodity 1 be provided at all by a monopoly? Explain your answer. If commonly 1 is provided by a monopoly, what would be Maggie's resulting utility?
