Discretion versus Policy Rules in Futures Markets: A Case of the Osaka-Dojima Rice Exchange, 1914-1939

We investigate the relationship between market efficiency of rice futures transaction in Osaka and the Japanese government intervention in rice distributions by directly buying and selling rice during the interwar period, from the middle 1910s to 1939, considering the context of "discretion versus rules." We use a time-varying VAR model to compare market efficiency and the government's actions over time. We found the two facts by featuring the time-varying nature of the market efficiency. First, the intervention with discretionary power disrupted the rice market and reduced market efficiency in the exchange. Second, the market efficiency improved in accordance with reduction in the government's discretionary power to operate the rice policy. When the government obtained the discretionary power to operate the policy regarding commodity market, the market efficiency often reduced. Conversely, even if the government implemented a large-scale intervention, the market efficiency improved when the government chose a systematic rule-like behavior following the law.

Market Integration in the Prewar Japanese Rice Markets

This paper examines the integration process of the Japanese major rice markets (Tokyo and Osaka) from 1881 to 1932. Using a non-Bayesian time-varying vector error correction model, we argue that the process strongly depended on the government's policy on the network system of the telegram and telephone; rice traders with an intention to use modern communication tools were usually affected by the changes in policy. We find that (i) the Japanese rice markets had been integrated in the 1910s; (ii) increasing use of telegraphs had accelerated rice market integration from the Meiji period in Japan; and (iii) local telephone system, which reduced the time spent by urban users sending and receiving telegrams, promoted market integration.

The Futures Premium and Rice Market Efficiency in Prewar Japan

This paper studies the interrelation between spot and futures prices in the two major rice markets in prewar Japan from the perspective of market efficiency. Applying a non-Bayesian time-varying model approach to the fundamental equation for spot returns and the futures premium, we detect when efficiency reductions in the two major rice markets occurred. We also examine how government interventions affected the rice markets in Japan, which colonized Taiwan and Korea before World War II, and argue that the function of rice futures markets crucially depended on the differences in rice spot market's structure. The increased volume of imported rice of a different variety from domestic rice first disrupted the rice futures. Then, government intervention in the rice futures markets failed to improve the disruption. Changes in colonial rice cropping successfully improved the disruption, and colonial rice was promoted to unify the different varieties of inland and colonial rice.

Market Efficiency and Government Interventions in Prewar Japanese Rice Futures Markets

This study analyzes how colonial rice trade in prewar Japan affected its rice market, considering several government interventions in the two rice futures exchanges in Tokyo and Osaka. We explore the interventions in the futures markets using two procedures. First, we measure the joint degree of efficiency in the markets using a time-varying vector autoregression model. Second, we examine many historical events that possibly affected the markets and focus on one event at a time. The degree varies over time within our sample period (1881-1932). The observation, together with historical analysis, leads to the following conclusions. (1) The two major markets in Tokyo and Osaka were nearly efficient. (2) Government interventions involving the delivery of imported rice from Taiwan and Korea often reduced futures market efficiency. Finally, (3) this relationship continued as long as the quality difference between imported and domestic rice existed. The government interventions that promoted domestic distributions of the colonial goods resulted in confusion in the commodity markets, and decreased efficiency of the markets in the metropole.
