Numerous conceptual and empirical studies advance the notion that first movers achieve long-term competitive advantages. These studies purport to demonstrate the presence of a systematic direct relationship between order of entry for products, brands, or businesses and market share. However, an objective assessment of the literature suggests that this view must be qualified. A broadened perspective is presented that highlights the complexity of this phenomenon and suggests that first-mover status may or may not produce sustainable advantages because of a multiplicity of controllable and uncontrollable forces. A conceptual framework identifying factors that underlie first-mover advantage and product-market contingencies that moderate the order of entry-competitive advantage relationship is proffered. Several research propositions relevant for marketing theory and practice are presented.
Existing innovation diffusion models assume that individual experience with the product is always communicated positively through word-of-mouth. For certain innovations, however, this assumption is tenuous since communicators of the product experience may transfer favorable, unfavorable, or indifferent messages through word-of-mouth. This paper examines a diffusion model for products in which negative information plays a dominant role, discusses its implications for optimal advertising timing policy and presents an application to forecast attendance for the movie Gandhi in the Dallas area.marketing, new products, diffusion models
