'Bernstein focuses on the real puzzle of the 1930s: why did the economy fail to recover from the downturn of 1929–1933? he presents a convincing case that there were important long-run tendencies within the economy that are crucial to understanding this failure. His approach cuts across the more traditional explanations which have been for the most part tests of economic theories rather than historical explanations of the depression. Bernstein's book is, in a word, impressive.' Roger Ransom, University of California, Riverside
