- Title
Technological Diffusion with Horizontal Product Differentiation and Adaptation Costs.
- Authors
Stoneman, P.
- Abstract
In this paper a model of diffusion incorporating horizontal product differentiation is analyzed. The analysis begins with the case of a single-brand monopolist, is extended to the multi-brand case and then to oligopoly. The speed of diffusion is shown to be related to the number of brands on the market, which in turn is determined endogenously. The model is further developed to analyze the impact on the diffusion path of a government subsidy to adaptation costs.
