Bundling and Nonlinear Pricing in Telecommunications

I develop a multiproduct nonlinear pricing model where a firm sells both discrete and continuous goods/services to consumers with multidimensional heterogeneity. I derive the optimal selling mechanism and provide primitive conditions under which different bundling strategies arise. Exploiting the optimality conditions of both the firm and the consumer, I show that the model structure is nonparametrically identified and propose a three-step semiparametric estimation procedure. An application to China Telecom data shows that mixed bundling is beneficial to both the firm and the consumer relative to component pricing
