This volume collects published papers and essays from widely scattered and inaccessible sources, some of which appeared for the first time when this book was originally published. In the first part of the book the subjects range from the theory of wages and recent trends in economic theory to economists’ criticism of capitalism and socialism, investment-policy in under-developed countries, and economic growth under the Soviet Five Year Plans. The second part includes papers on Lenin and Marx, a study of the economic ideas of Bernard Shaw, and an essay on historical materialism.
