publisher faces the following demand schedule for the next novel from one of its popular authors: Price Quantity Demanded 100 0 90 100,000 80 200,000 70 300,000 60 400,000 50 500,000 40 600,000 5 30 700,000 20 800,000 10 900,000 0 1,000,000 The author is paid $2 million to write the book, and the marginal cost of publishing the book is a constant $30 per book. a. Compute total revenue, total cost, and profit at each quantity. What quantity would a profitmaximizing 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?

The author is paid $2 million to write the book, and the marginal cost of publishing the book is a
constant $30 per book.
a. Compute total revenue, total cost, and profit at each quantity. What quantity would a profitmaximizing 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
marginal-revenue and marginal-cost curves cross? What does this signify?
d. In your graph, shade in the
e. If the author was 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 was not profit-maximizing but was concerned with maximizing economic
efficiency. What price would it charge for the book? How much profit would it make at this
price? (
