Professor Sutton's thought-provoking book is directed principally to the question: ‘Are simple mathematical models helpful in economics, or are they misleading?’ His answer, baldly stated, is that if they are made right they are helpful, but if they are made wrong they are misleading.
He has in mind an ideal reader: someone who already knows from other fields how a successful theory based on formal mathematical models works, but who has only recently stumbled on economics, and is skeptical about formal mathematical models here. I am not quite an ideal reader now, but I was once, because I studied and worked in physics before going into economics.
