Estimating Substitution and Expansion Effects Using a Profit Function Framework
首次仅利用利润函数推导产业生产结构的所有相关信息，基于加拿大农业数据分离投入和产出的替代与扩张效应，发现作物与动物生产非联合且雇佣劳动与经营者劳动互补。
Abstract This study reports a first attempt to derive all the relevant information with respect to the structure of production of an industry using knowledge of only a profit function. Using estimates of a profit function for Canadian agriculture, a procedure to separate substitution and expansion effects for both inputs and outputs was implemented. Information concerning net input and output substitution and complementarity possibilities were obtained. The most important empirical results suggest that the hypothesis of nonjoint production of crop and animal outputs in Canadian agriculture cannot be rejected, and that hired and operator labor are complements rather than substitutes.
