We conduct Monte Carlo experiments to investigate the biases in structural estimation of demand for differentiated products when the assumed demand functional form is misspecified. We focus on aggregate data (i.e. not individual purchase decisions) and generate stochastic equilibrium price and...

The diffusion model developed by Bass (Bass, F. M. 1969. A new product growth model for consumer durables. (January) 215–227.) constitutes an empirical generalization. It represents a pattern or regularity that has been shown to repeat over many new products and services in many countries and...

It is our hope that some of the empirical generalizations presented in this volume would be of practical value to management. Some of the generalizations help codify our knowledge—they are discussed in several papers—some can serve as useful guidelines in the generation of strategic...

Marketing has matured to the point where it seems desirable to take stock of where we are, what we have learned, and fruitful directions for extending the knowledge base that has developed. Science is a process involving the interaction between empirical generalizations and theory. An is “a...

A regression method for estimating geographic market potentials is developed. Aggregation issues are explored, and a macro model is derived in which it is not necessary to assume that the relationships among variables are the same within the micro subsystems. An estimating procedure is presented...

A growth model for the timing of initial purchase of new products is developed and tested empirically against data for eleven consumer durables. The basic assumption of the model is that the timing of a consumer's initial purchase is related to the number of previous buyers. A behavioral...

This study deals with the dynamic sales behavior of successive generations of high-technology products. New technologies diffuse through a population of potential buyers over time. Therefore, diffusion theory models are related to this demand growth. Furthermore, successive generations of a...

Over a large number of new products and technological innovations, the Bass diffusion model (Bass 1969) describes the empirical adoption curve quite well. In this study, we generalize the Bass model to include decision variables such as price and advertising. The generalized model reduces to the...
