This paper reconsiders the effects of population growth on per-capita income growth within a Romerian (1990)-type endogenous growth model with human capital accumulation. One important novelty of our contribution is that in the human capital accumulation equation we explicitly consider the...

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...

This paper analyzes how population and product market competition may interact with each other in affecting the pace of productivity growth. We find that the impact of a change in population (size/growth) and in the degree of market concentration on economic growth varies depending on the...

This paper analyzes the conditions under which, within a two-sector endogenous growth model with human and physical capital accumulation but without R&D-driven disembodied technological progress, it is possible to observe an ambiguous effect of population growth on economic growth, as empirical...

Using a balanced-growth model with physical and human capital accumulation, this article analyzes quantitatively the long run effects of changes in the saving rate and in income distribution (i.e., the shares of physical and human capital in income) on investment in human capital, growth of...
