Spatial Monopoly with Upgrades of Durable Goods
Spatial Monopoly with Upgrades of Durable Goods

Summary/Abstract: This paper establishes a two-stage Hotelling model to identify the implications of the upgrades of durable goods produced by a spatial monopoly. The major findings indicate that, due to the positive effects on profits of the upgrading of products, the monopoly has the motivation to launch upgraded versions with high quality instead of solely producing products with low quality. The monopoly, meanwhile, would not make a commitment to either the high-quality products or the low-quality ones. In addition, the price of the low-quality products decreases as upgraded ones appear on the market in a second stage, since no consumers would store the low-quality products for future consumption.
