"The macro-principles textbooks don’t represent our field well. Little of the exciting work that’s been done by this group has made its way into undergrad textbooks. That’s probably inevitable. But it leads to a real misunderstanding about what macroeconomists do – both among lay-people and among economists in other fields. I hope that some of our gifted textbook writers rectify that situation soon!"
