Abstract
This paper provides a disaggregated productivity comparison between Japan and the U.S. for the period 1885–1990. It combines two detailed productivity comparisons for 1939 and 1975 with time series to provide a long‐term sectoral perspective. There is much diversity in the Japanese experience. The agricultural sector has shown relative stagnation since 1885. The service sector showed considerable growth before the Second World War and reached high productivity levels in the post‐war period. Within services there is great diversity in productivity levels. Japan's manufacturing sector has shown the fastest catch‐up and its productivity level is currently close to that of the U.S.
