A long, detailed technical job which we cannot pretend to cover adequately. It is an inquiry into the financial and non-financial institutions of security capitalism, based on the premise that general economic processes are determined by changing institutions rather than fixed laws. The author wishes to indicate the principles of private and public control which will enabl the capitalistic system to function at its best for individual profit and social welfare. He takes France, England, Germany and the U.S.A., -- financial institutions, pre-war and post-war conditions, problems of today and yesterday, conflict between federal and individual control, etc. Has none of the interpretative aspects of Folklore of Capitalism and is of more limited appeal, but there is a tie-up there, for those who are interested in the statistical side. Advance copies will be available shortly and there are to be circulars for bookshops, carrying endorsements. The author is the chairman of the Department of Economics, City College of New York.
