While the new product literature suggests that managerially controllable factors most strongly affect new product success, few studies have examined how these factors differ across countries. The objectives of this article are: (1) to develop a model of factors associated with new product...

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...

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...

A consistent pattern observed for really new household consumer durables is a takeoff or dramatic increase in sales early in their history. The takeoff tends to appear as an elbow-shaped discontinuity in the sales curve showing an average sales increase of over 400%. In contrast, most marketing...

It is a popular contention that products launched today diffuse faster than products launched in the past. However, the evidence of diffusion acceleration is rather scant, and the methodology used in previous studies has several weaknesses. Also, little is known about why such acceleration would...

Influential forecasts occur when the forecast itself determines whether the forecast is tested. New product sales forecasts are often influential because a low forecast may cause a firm not to launch a new product so that actual sales are never observed. This paper considers a dilemma we face as...

This paper proposes a descriptive model of the spatial and temporal evolution of retail distribution for new packaged goods. The distribution model postulates separate processes for local market entry by manufacturers, and adoption by retailers given entry. Of special interest is whether retail...
