Abstract

In a vertically differentiated monopolistic framework with discrete preferences we examine how protecting the low-quality segment raises the incentive for quality innovation. We show how the monopolist facing competitive imports, might fail to exert its complete monopoly power even if there is prohibitive tariff on both the high and low quality segment of the market. On the other hand, given non prohibitive tariff on the high quality segment, the potential gain for the monopolist exhausts at a level much below the prohibitive low-quality tariff level. Also a sufficiently low tariff on the high quality product can force the monopolist to produce the first best qualities irrespective of the tariff level on the low quality product
