Title: A book that did not deserve to be published
Review: I have read this book twice and see no reason why the author wrote this book. The book is not written in a language that will introduce the subject to the beginners and those who know something will be confused. Bradford Delong is a below average writer. His grammar is definitely not strong. It would have helped if his editor had been a good one. Please do not write another edition of this book for it is not going to benefit anyone. As an academic De Long should be ashamed of his credentials. In short, I give this book a generous D- for all the effort. F grade for his writing and a D for his presentation. If you can please avoid this book for it is not worth the price you are paying for it.
