The Output Bias of Technological Change in Postwar Japanese Agriculture
检验了战后日本农业技术变革偏向畜牧业的假设，发现技术变革确实偏向畜牧业，且畜牧业扩张比种植业更少使用劳动力，加速了劳动力向非农部门转移。
Abstract In order to explain the rapid change in the output mix, this study tests the hypothesis that technological change in postwar Japanese agriculture was biased towards livestock production. A multioutput translog cost function was estimated for the 1958–84 period in which results are consistent with the hypothesis. Furthermore, changes in the composition of crop and livestock production had significant impacts on relative factor uses. Above all, expanding livestock production required relatively less labor than expanding crop production, implying a positive contribution to the rapid exodus of labor to the nonagricultural sectors.
