I.I. Rubin was the most important economist in the Soviet Union in the 1920s and is still influential today in Marxian scholarship around the world. This book presents assessments of Rubin’s legacy for Marxian scholarship by 10 Marx scholars from six different countries and will be essential reading for Marx-Rubin scholars going forward. The main controversy continues to be the relative significance of production and circulation in the determination of the value of commodities. A majority of authors in this book conclude that Rubin’s predominant view in the later editions of his book was that value is determined in production and realized in circulation, which is contrary to the popular value-form interpretation of Rubin’s book.
