David closes his review with a bullet to Krugman's head:
Krugman has nothing to say about the Austrian theory of the business cycle. Hayek is mentioned once (p. 205) in connection with the passage from Schumpeter previously quoted, but his name does not appear in the book's index. Mises and Rothbard are not mentioned at all. Given his manifest lack of understanding of the Austrian theory in earlier work, this is just as well.The full review is here.
