THE THEORY OF AGRICULTURAL RESEARCH BENEFITS
提出基于成分收益而非传统剩余收益的农业研究收益新理论,将多种已有方法作为特例推导并数值比较,简要讨论应用,如用Griliches II分析作物产量变异性。
This paper describes a new approach to the theory of agricultural research benefits based on component benefits rather than, as is customary, on surpluses. The surplus concept nevertheless emerges when the distribution of the national benefit is considered. Various published methods (Grossfield‐Heath, Lindner‐Jarrett, Akino‐Hayami, Griliches I and II) are derived as special cases of the theory and numerically compared. Applications are briefly considered; Griliches II is used for the variability of crop yields and some typical results for the distribution of benefits are given.
