Abstract

This paper discusses a model of vertical an horizontal product differentiation within the Dixit-Stiglitz framework of monopolistic competition. Firns coompete not only in prices and horizontal attributes of their products, but also in the quality that can be controlled by R&D activities. Based upon te results of a general equilibrium model, intra-sectoral trade and the welfare implications of public intervention in terms of research promotion are considered. The analysis involves a numerical application to ten basic European industries.
