- Scenario 1: Barbara is a producer in a monopoly industry. Her demand curve, total revenue curve, marginal revenue curve, and total cost curve are given as follows: Q = 160 - 4P TR = 40Q- 0.25Q?

The firm O A. is a natural monopoly because its demand curve is downward sloping. O B. is a natural monopoly because it has the potential to earn economic profits. OC. is not a natural monopoly because its demand curve is not infinitely elastic. O D. is not a natural monopoly because it experiences diseconomies of scale. OE E. is a natural monopoly because it can supply the entire market at lower average total cost than can two or more firms. Suppose 14 units of output are supplied in the market. How much lower is the average total cost of production for one firm compared to two firms? One firm can supply 14 units of output for $less per unit in average total cost than two firms.
