The royalties received by an author for writing a college text are frequently set at a rate of about 15 percent of the publisher's book price. This may create a conflict between the goals of a profit-maximizing publisher and those of a royalty-maximizing author. As a student consumer (assuming you have to pay for your textbooks), whose goal would be more beneficial to you? Why? Demonstrate this situation graphically (assume a downward-sloping demand curve).
