The paper explores the relationship between the price elasticity of demand and the research and development (R&D) intensity of the product. The authors introduce the concept of R&D intensity into a standard Dixit-Stiglitz/Krugman-type setting, and R&D activity is treated as a fixed cost of production. Within this framework, sectors with a higher R&D intensity show a lower price elasticity of demand.
