Induced Bias of Technical Change in Agriculture: The United States and Japan, 1880-1980
利用两级CES生产函数检验希克斯诱导创新假说，分析1880-1980年间美日农业因要素禀赋和相对价格差异导致的不同技术变迁模式。
Because of extreme differences in factor endowments and price ratios among factors between the United States and Japan, both countries have experienced sharply different patterns of factor use and productivity growth in agriculture for the past 100 years of modern economic growth. In this study, the method of testing the Hicksian hypothesis of induced innovation was developed using the two-level CES production function. The model was applied to the historical data of U.S. and Japanese agricultural development for 1880-1980. The results were consistent with the hypothesis that different patterns of technical change in the two countries were induced by differences in the levels and the movements in relative factor prices.
