This paper suggests the optimal level of public stock of rice against bad crop in a global scale, as experiences in the "World Food Crisis" of 1973-74. The average public stock holding of rice is estimated by 14-15% of total rice consumption and its minimum level is estimated by 7-9%

Most developed countries have already changed their agricultural policy from price support programs to direct payment because direct payment does not affect the resource allocation and is more efficient than the price support. Government procurement policy which is the most typical price support program is well known to influence the efficiency of resource allocation. In this paper, the benefit of farmers obtained from the government procurement policy of rice in Korea is estimated to be only 2∼6% of government expenditure. Therefore, the costly and inefficient government procurement program needs to be converted to direct payment system.

The purpose of this paper is to provide the desirable rice policy to stabilize the rice market. This paper suggests a special disposal to protect the rapid decrease in rice price caused by temporary good harvest. And it suggests to be reformed for the variable direct payment program to be decoupled since the decoupled direct payment program is economically the most efficient policy for solving a problem of the structural oversupply.

This article proposes the desirable price stabilization schemes from the point of the producer under production uncertainty. This article shows that the current price stabilization policy is not desirable even to producers and is not able to be kept in the long-run. The desirable price stabilization policy by government buffer stock makes the inelastic demand curve to be almost unitary and the average stock level should not be constant.
