This book has its origin in a resolution adopted by the Assembly of the League of Nations in September 1930 by which it was decided that an attempt should be made to co-ordinate the analytical work then being done on the problem of the recurrence of periods of economic depression. This book is divided into two parts. The first part contains a systematic analysis of existing theories; the second an attempt to weave from those theories a general synthesis.
