Nonparametric Tests of Profit Maximization in Oligopoly with Application to the Beef Packing Industry
开发了非参数方法检验非竞争行为下的静态利润最大化，通过重复检验得到非竞争程度的“最大似然”估计，并用工厂级数据检验牛肉包装商是否利润最大化及对活牛市场价格的影响。
Abstract In this paper, we develop new, nonparametric methods of testing for static profit maximization given noncompetitive behavior. Repeated application of the test yields “maximum likelihood” estimates of the degree of noncompetitive behavior. Using plant‐level data, these newly developed nonparametric methods are employed to test the hypothesis that beef packers are profit maximizers and to measure the extent to which packers influence prices in fed‐cattle markets.
