A markup over average cost pricing rule for meat and poultry in the United States
研究了美国肉类和家禽批发商如何同时决定库存和批发价以最大化利润，发现加成率与库存销售时间价格弹性倒数一致，对理解肉类定价机制有帮助。
This paper tests the hypothesis that meat and poultry wholesalers choose their inventory levels together with wholesale price so as to maximize profit made over the sales time of their stock. The behavioral assumption predicts that markup over average cost will match the inverse of the price elasticity of the sales time of inventory. Price elasticity of inventory sales time is estimated for beef, pork and poultry accounting for the simultaneity between these pricing decisions by adopting a systems approach. The estimated range for the inverse of these elasticities includes all the markups applied over the sample range of the time series.
