The influence of the degree of competition in the goods market on growth is analyzed by developing an endogenous growth model with horizontal innovation. Product market competition is measured by (1- Lerner index) and depends on both the share of factor inputs in total income and on the...

The influence of product market competition on growth is reconsidered by developing an extension of the basic Romerian model of horizontal product innovation. We find that the relationship between competition and growth is inverse-U shaped, provided that the non accumulated factor input (e.g....

We build a generalised growth model of horizontal product innovation with human capital accumulation in which the monopolistic mark-up set in the uncompetitive sector and the degree of returns to specialization are disentangled. We find that product market power has a positive growth effect when...

This paper studies the economic determinants of the inter-sectoral allocation of skills within an R&Dbased growth model with human capital accumulation. I find that steady-state growth is driven only by incentives to accumulate skills and is independent of scale effects. In the model imperfect...

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...

This paper studies the economic determinants of the inter-sectoral allocation of skills within an R&Dbased growth model with human capital accumulation and imperfect competition. Using an aggregateR&D technology displaying constant returns to scale in human capital, I find that steady-state...

This paper studies the long-run consequences of imperfect competition on growth and the sectoral distribution of skills within an R&D-based growth model with human capital accumulation. We find that steady-state growth is driven only by incentives to accumulate skills. In the model imperfect...
