The Limited Gains From Complex Tariffs

Abstract

This paper uses an equilibrium model of multipart nonlinear pricing to determine the magnitude of foregone profits due to the implementation of simple tariff options. I then use the available information from a cross-section of independent cellular telephone markets to study how these foregone profits vary with markets' observable characteristics. Results show that commercialization costs effectively limit the number of tariff options offered to consumers. The evidence presented in this paper suggests that firms should only offer a few tariff options if their commercialization and product development costs are non-negligible. More importantly this evidence favors the use of two-part tariffs and other simple pricing strategies in theoretical modeling in order to overcome the analytical difficulties of the existing general models of nonlinear pricing and thus responds to the many open questions in the area of nonlinear pricing.
