Forecasting sales of new contingent products: An application to the compact disc market

Abstract

Estimating the sales potential of new products before an actual launch is a major problem confronting marketing and new products managers. Several modeling efforts for both new durable products and consumer package goods have been reported. An area which has received little explicit treatment, however, is that of new contingent product sales. A specific case of such products is the close relationship between software (consumables or accessory items subject to repeat good required for use of the software). Examples of this relationship include video cassette recorders and VCR tapes; microcomputers and floppy diskettes; and cameras and photographic film. In this article Barry Bayus discusses a practical method for estimating hardware and software sales of such products. Effects due to different market segment behaviors, pricing, awareness levels, and purchase intentions are incorporated into the model. Results from a study of the compact disc prerecorded audio market by RCA/Ariola are presented in order to illustrate how the model can be applied and how the results are useful in making managerial decisions.
