Abstract

This paper develops a dual economy endogenous growth model to consider the effects of market structure and innovation on the rate of growth of an economy. There is an innovative goods sector where firms consistently invest in research and development to produce new products within a framework of monopolistic competition. Firms in the traditional goods sector produce a homogenous good, compete in a form of oligopoly (quantity competition), and seek to reduce their production costs. It is shown that growth is increasing in the market power that firms in the innovative goods sector obtain but decreasing in the equilibrium number of firms in the traditional goods sector.
