An Economic Analysis of Technology in the Meat Products Industry
估计了肉类产品行业的非齐次成本函数，发现1972-76年间该行业存在规模报酬递增，且要素价格变化显著影响规模经济和技术进步率。
Abstract A nonhomothetic cost function allowing for variable elasticities of scale and substitution and neutral, as well as factor‐using, technical change is estimated for the meat products industry. Empirical results suggest that over the period 1972–76 this industry was characterized by increasing returns to scale. The nonhomothetic and nonneutral specification implies that returns to scale and the rate of technical progress are significantly affected by factor price changes and the level of output. Higher labor prices lead to greater scale economies and to greater cost reductions through technological advances.
