a. Suppose the marginal social cost of television sets is $100. This is constant and equal to the average cost of television sets. The annual demand for television sets is given by the following equation: Q = 200,000 – 500P, where Q is the quantity sold per year and P is the price of television sets. If television sets are sold in a perfectly competitive market, calculate the annual number sold. Under what circumstances will the market equilibrium be efficient?
b. Show the losses in well-being each year that would result from a law limiting sales of television sets to 100,000 per year. Show the effect on the price, marginal social benefit, and marginal social cost of television sets. Show the net loss in well-being that will result from a complete ban on the sales of television sets.
