The author is paid$2million to write the book, and the marginal cost of publishing the book is a constant$1per 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 = ^TR / ^Q.) 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$3million instead of$2million to write the book, how would this affect the publisher's decision regarding what price to charge? Explain.

f. Suppose the publisher was not profit-maximizing but was instead concerned with maximizing economic efficiency. What price would it charge for the book? How much profit would it make at this price?
