This is one of the best books in its field. Professor Mason of Harvard has had governmental experience in dealing with the problems he discusses in this study, prepared for the Committee for Economic Development. Half the book is devoted to international business arrangements and half to intergovernmental commodity agreements. Professor Mason recommends several courses of international action to control cartels and discusses desirable United States policy in the absence of international agreement. After a concise analysis of the raw material problem, he concludes that intergovernmental commodity agreements should be subordinated to understandings about international trade in general.
