Ten years ago, by coincidence, I saw this book. I bought it, and since then I have recommended it to all my colleagues.
At that time, the book was new and contained all the most recent developments in the journals (it ends with hysteresis - well explained and at that moment a brand new topic in the journals).
But what I find more important is that this is the only book I read where all those journal-stuff was fitted into a coherent frame-work; for the first time I really understood what macro-economics (and their micro foundations) was all about.
Up till then, I had seen only fragmented pieces of macro theory and here these authors came with a coherent view, which would have taken myself years to fit together, and I was sorry that this was not the handbook I had at university.
I don't follow-up this field anymore, and the book has not been updated anymore since then (a pity I think) but I write this review out of gratitute for the insights the authors gave me: I finally realized that in this book all the pieces were fitted together and allowed me to really understand macro-economics.
Personally, I can only recommend it.
