SUMMARY:Isabelle Perrigne - Rice University
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Multiproduct Nonlinear Pricing: Mobile Voice Service and SMS (with Yao Luo 
 and Quang Vuong)\nAbstract:\nThis paper studies multiproduct nonlinear pric
 ing in the cellular phone industry with voice and message services. The mod
 el derives from Arsmtong (1996) in which the unknown types of consumers are
  aggregated while the firm designs an optimal cost-based tariff. As usual i
 n multidimensional screening problems, there is pooling at equilibrium. Mor
 eover, given that the consumers add a large number of unobserved extra feat
 ures, we introduce two terms of unobserved heterogeneity for voice and mess
 age add-ons. The model defines two one-to-one mappings between the unknown 
 aggregate type to the cost and the cost to the payment. We then study the i
 dentification of the model primitives. Under some identifying assumptions s
 uch as a parameterization of the cost function, we show that the primitives
  of the model (the aggregate type density, the indirect utility and the joi
 nt density of unobserved heterogeneity) are identified from observables. Th
 e empirical results support the model and display an important heterogeneit
 y in types and unobserved heterogeneity. The cost of asymmetric information
  for the firm is assessed. Counterfactuals measure the benefits of a custom
 ized tariff relative to a standard tarification with a limited number of pl
 ans that include a large number of features.\n
