Details The purpose of this study is to examine how the efficiency and the integration speed of rice market in Japan increased before Second World War. Concretely, we employed time-varying econometric models using the monthly spot and futures prices in Tokyo and Osaka. We found the following four facts by featuring the time-varying nature of the efficiency and integration of the market. First, government interventions involving the delivery of imported rice from Taiwan and Korea often reduced futures market efficiency before First World War. Second, the government interventions did not reduce the market efficiency after the 1920s. Third, the market efficiency improved in accordance with reduction in the government’s discretionary power to operate the rice policy under the Beikoku Ho (the Rice Law) and the Beikoku Tousei Ho (the Rice Control Law). Fourth, the increasing use of telegraphs accelerated rice market integration until the end of the 1910s.
