R&D, Competition and Growth with Human Capital Accumulation : A Comment

This paper shows that the results of Bucci (2003) depend criti- cally on the assumption that there are no difference between the intermediate goods share in final output, the returns of specialization and the degree of market power of monopolistic competitors. In this paper, we disentangle the market power parameter from the intermediate goods share in final output and the returns to specialization. The main result of this paper is that the competition has no effect on growth contrary to Bucci (2003). This result is explained by the fact that economic growth rate depends on the parameters describing preference and the human capital accumulation technology but is completely independent of competition and R&D activity.
