I regret to say that this is not a good accompaniment for my graduate macroeconomics class. I thought I could somehow get some mileage out of this book, but as I read it I found out that its lack of technical details and rigor make my lecture notes look superior. I was misled to think that this is a great textbook through the early positive reviews below, that's why I bought it. Nevertheless, the empirical content is more than enough to satisfy one's curiosity, but I think it is not worthwhile to study advanced macroeconomics without learning fully the necessary theories and the accompanying mathematical techniques. This textbook must not be the choice for a core graduate level macroeconomics class; it's wordiness is comparable to the undergraduate textbook "Intermediate Microeconomics" text by Varian. It is readable of course, when you want to pass the time, but it won't do for a graduate level text. I'm disappointed because this is the second edition already but still the author stuck to the same way of presentation. Perhaps the only differences between the first and the second edition are the empirical data sets and a new chapter and nothing else. The first three chapters and chapter 7 of Obstfeld and Rogoff's treatise, "Foundations of International Macroeconomics," Barro and Sala-i-Martin's, "Economic Growth," and the chapters 2,3 and 4 of Blanchard and Fischer's, "Lectures in Macroeconomics," provide a more comprehensive view of modern acroeconomics.
