Textbook publishers hope to maximize profits. Authors, however, face very different incentives. Authors are typically paid royalties, which are a specified percentage of total revenue from the sale of a book. And so, for example, if an author’s contract says that she will receive 20 percent of the revenues from the sale of a text and the publisher’s total revenues are $100,000, the author’s royalties will be $20,000. Who will prefer a higher price for the text, the publisher or the author?
