A MODEL OF IMPERFECT COMPETITION USING MARGINAL INPUT AND OUTPUT PRICES: APPLICATION TO THE BEEF PACKING INDUSTRY
基于Diewert的思想，用边际价格将竞争模型推广到不完全竞争，开发了一个检验牛肉包装行业不完全竞争的方法，比依赖弹性估计的模型更灵活通用。
Based on Diewert's idea that models under competition can be generalized to imperfect competition using marginal prices, we develop a test for imperfect competition in the beef packing industry. Our model is more general and flexible than those depending on empricial estimates of the input supply and output demand elasticities.
