The Debt-Deflation Theory of Great Depressions

IN Booms and Depressions, I have developed, theoretically and statistically, what may be called a debt-deflation theory of great depressions. In the preface, I stated that the results seem largely new, I spoke thus cautiously because of my unfamiliarity with the vast literature on the subject. Since the book was published its special conclusions have been widely accepted and, so far as I know, no one has yet found them anticipated by previous writers, though several, including myself, have zealously sought to find such anticipations. Two of the best-read authorities in this field assure me that those conclusions are, in the words of one of them, both new and important. Partly to specify what some of these special conclusions are which are believed to be new and partly to fit them into the conclusions of other students in this field, I am offering this paper as embodying, in brief, my present on the whole subject of so-called cycle theory. My consists of 49 articles some of which are old and some new. I say because, for brevity, it is purposely expressed dogmatically and without proof. But it is not a creed in the sense that my faith in it does not rest on evidence and that I am not ready to modify it on presentation of new evidence. On the contrary, it is quite tentative. It may serve as a challenge to others and as raw material to help them work out a better product. Meanwhile the following is a list of my 49 tentative conclusions.
