1980年代におけるアメリカのコメ政策の稲作経営の分割及び稲作の効率性への影響

Abstract

Some specific elements of the recent U. S. rice policy (program) such as the 50, 000 dollar limitation in the Federal direct payment to each farm caused wide spread divisions of larger rice farms and affected efficiency in rice production in the United States. This paper, first, describes the recent developments and their economic implications in the U. S. rice program. Secondly, the effects of some of these developments to the division of the larger rice farms and efficiency in rice procuction in the United States are theoretically and empirically analyzed. Finally, the durability of the recent U. S. rice program is investigated based on the evaluation of the effects of the Federal rice program such as the unfair distribution of the Federal subsidy toward the larger rice farms and the decrease in the efficiency of rice production.
