(CAMBRIDGE, Mass.) -- A new version of a widely-used economics textbook, Principles of Economics, no longer uses Tiger Woods as an example to explain economic theory.
Previous editions of the textbook used an example entitled, "Should Tiger Woods Mow His Own Lawn?" The sixth edition of the book replaced the previous example with one featuring quarterback Tom Brady, as first reported by the Harvard Crimson.
“I wanted students to focus on the economics of comparative advantage -- the main point of this section of the book,” wrote Greg Mankiw in an email to ABC News. “I was afraid that keeping Tiger Woods in the hypothetical example would have raised thoughts of an altogether different set of issues."
Prior to the textbook using Tiger Woods, Mankiw said the book featured Michael Jordan, before the famous basketball player retired.
Mankiw told the Harvard Crimson that he and his editor chose New England Patriots quarterback Tom Brady because he was another celebrity athlete.
Woods is currently competing in the PGA Tour's Arnold Palmer Invitational in Florida, which ends on Sunday.
