Abstract

Technological innovation, externalities and network effects keep shifting the preference parameters in cellular telecommunication service sector. The paper suggests a framework to model these changes. It notes two channels that affect the service prices (in possibly opposite ways). In each corresponding period, consumer with lower reservation prices are shopping for the services. But these reservation prices are going up due to complementarity/network effects.

Under some reasonable assumptions on industry and cost structure, market data can be used to identify these changes. A price index is suggested that decomposes service bundle price changes into the change in price for same-quality of service and change in quality of the service bundle. Some interesting properties of these indexes are also discussed.
