Estimating Coke's and Pepsi's Price and Advertising Strategies
用半参数信息估计法估算可口可乐和百事可乐的价格与广告策略，并检验博弈论假设及收入、要素价格变化的影响。
A semiparametric, information-based estimator is used to estimate strategies in prices and advertising for Coca-Cola and Pepsi-Cola. Separate strategies for each firm are estimated with and without restrictions from game theory. These information/entropy estimators are consistent and efficient. These estimates are used to test theories about the strategies of firms and to see how changes in incomes or factor prices affect these strategies.
