Nobel Laureate Simon Kuznets, famous as the founder of modern empirical economics, pioneered the quantitative study of the economic history of the Jews. Yet until now his most important work on the subject was unpublished. These volumes bring to the public, for the first time, the most important work written on Jewish economic history since that of Werner Sombart a century ago. In the first volume, Kuznets uses extensive, original data to trace trends in the economic life of American Jews. He measures quantitatively for the first time the legendary economic success of American Jews and discusses the foundations of these achievements. Tracing their distinctive concentration in the professions, he exposes the causes of the extreme inequalities in American Jewish economic life. The immigrant origin of nearly all American Jews offers a unique case study in the process of assimilation that made American Jewry the ultimate American success story. This offers an ideal prelude to the second forthcoming volume, Comparative Perspectives on Jewish Migration. The volume’s editors also provide a unique perspective on Kuznets’ work. In the introduction, Weyl shows that many of Kuznets’ most influential ideas, were inspired by his study of the economic history of the Jews. Through careful analysis of shared themes, and dozens of hours of detailed interviews, Lo and Weyl reveal a new dimension of Kuznets’ thought to historical inquiry.
