On Discarding Low Quality Produce
研究在非线性需求下，企业如何通过剔除低质量产品（即“剔除”）来最大化行业总利润，分析了需求函数凹凸性和价格弹性对盈亏平衡质量价格变化曲线的影响。
Abstract This paper considers a model of optimal culling in which demand is generally nonlinear. We show that the shape of the break‐even quality price change curve depends on both the concavity‐convexity of the demand function and the price elasticity. We specify that the actual quality price change is an increasing function of the minimum quality but at a decreasing rate. Conditions ate then obtained to ensure that a minimum quality level chosen from a permissible set would yield maximum total profits for the industry.
