Bundling and nonlinear pricing in telecommunications
构建了一个多产品非线性定价模型，分析企业如何对离散和连续服务进行最优定价，并利用中国电信数据发现互联网与固话的混合捆绑比单独定价更有利于企业和消费者。
Abstract I develop a multiproduct nonlinear pricing model where a firm sells both discrete and continuous services to consumers with multidimensional heterogeneity. I derive the optimal selling mechanism and provide primitive conditions under which different bundling strategies arise. Exploiting both the firm and the consumer's optimality conditions, I show that the model structure is nonparametrically identified and propose a semiparametric estimation procedure. An application to China Telecom data shows that mixed bundling of internet and landline phone services is more beneficial to both the firm and the consumer relative to component pricing.
