In the late 1940s, the Japanese economy transited to a market economy from an
economy under the government planning and control, which had continued since the
period of the Sino-Japanese War. This paper explored the impact of the transition on the
micro-aspect of the economy, focusing on the coal mining industry. By comparing
productivity of coal mines before and after the transition, we found that the price
control indeed hurt the incentive for coal mines, in particular relatively efficient ones, to enhance productivity.
