A durable-goods monopolist who will be introducing new and improved versions of his product must decide how to price his products, keeping in mind the relative attractiveness of the current and future products. Dhebar (1994) has shown that if technology is changing too quickly and the producer cannot credibly commit to future prices and quality, then no equilibrium strategy exists. That is, there is no credible strategy for the future product that the producer can commit to in the first period. We show that an equilibrium pricing strategy exists if the monopolist does not offer upgrade pricing, that is, special pricing to consumers who have bought an earlier version. The author shows the possible purchase patterns in equilibrium and derives the optimal pricing strategy.
