Abstract

This paper overviews the main interactions between product market competition and long run growth. We focus on the first generation of R&D-based growth models and keep distinguished the vertical from the horizontal differentiation approaches. Our main objective is to study why these two branches of the same literature give different predictions as far as the long-run relationship between competition and growth is concerned. At this aim we introduce a generalised version of the growth models with horizontal differentiation and deterministic R&D activity which allows us to highlight the main differences between the two research lines. In the second part of the article we also review the literature that endogenises the markups and eliminates the scale-effects prediction.
