A few points:
- This is one of the first, and few, macroeconomics books that dedicated a chapter to Austrian economics.
- More than a macroeconomics textbook, I see it as a history of macroeconomic analysis (in the Schumpeter way). It starts with the classical approach, then with the orthodox Keynesian model, then the IS-LM model for an open economy, monetarism and son on.
- The history of macroeconomics analysis is a history of revolutions and counterrevolutions. There are as well schools of thought that developed parallel to the "mainstream."
- There is some chronological overleaping as well, for example the Mundell-Fleming model was developed by the time the monetarism revolution was starting in the early 1960s.
- The history of macroeconomic analysis is fascinating and the book makes it clear that it is an evolving field, and very likely what is in vogue today might well not be discuss in a few years - some current theories will be incorporated into the "mainstream," but not necessarily.
