【简答题】
A publisher faces the following demand schedule for the next novel by one of its popular authors: The author is paid $2 million to write the book, and the marginal cost of publishing the book is a constant $10 per book. a. Compute total revenue, total cost, and profit at each quantity. What quantity would a profit-maximizing publisher choose? What price would it charge? b. Compute marginal revenue. (Recall that MR= ΔTR/ΔQ.) How does marginal revenue compare to the price? Explain. c. Graph the marginal-revenue, marginal-cost, and demand curves. At what quantity do the marginal- revenue and marginal-cost curves cross? What does this signify? d. In your graph, shade in the deadweight loss. Explain in words what this means. e. If the author were paid $3 million instead of $2 million to write the book, how would this affect the publisher’s decision regarding the price to charge? Explain. f. Suppose the publisher were not profit-maximizing but were concerned with maximizing economic efficiency. What price would it charge for the book? How much profit would it make at this price?
