Evgeny A. Preobrazhensky was Russia's foremost economist in the 1920s. This volume editorially reconstructs his theory of socialist industrialisation in an agrarian country and relates it to previous socialist theories and to issues of political struggle, culture and communist morality. The bulk of the work included in this volume consists of Preobrazhensky's Concrete Analysis of the Soviet Economy, which supplements his theoretical inquiry published in Volume II. A number of appendices present Preobrazhensky's analysis of the NEP and his correspondence with Trotsky alongside extensive contributions by the volume's editors and translators.
