With Sweat & Abacus: Economic Roles of Southeast Asian Chinese on the Eve of World War Two. Fukuda's seminal study (1939), now translated for the first time from Japanese into English, rivals that  of his great English contemporary, Victor Purcell's own magnum opus, The Chinese in Southeast Asia  (1951).  Fukuda study is truly comparative and shows the reader why and how the economic outcome differed from country to country in the region.  This intensely well-researched and analytica study was originally published in Japanese as "Kakyo keizai-ron" or "The Overseas Chinese economy" and is a important addition to our understanding of the Chinese diaspora.
