Abstract This paper extends public spending-based growth theory along three directions: we assume that exogenous and constant technological progress does exist and that both population change and the ratio of government expenditure to income follow a logistic trajectory. By focusing on the...

Using an integrated model of purposive R&D activity and human capital accumulation, this paper analyses the joint impact that product market competition may exert on the sectoral distribution of skills and economic growth. In a framework where innovation takes place through an R&D technology...

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 examines two possible sources of interaction between private and public capital in an endogenous growth model with productive public investment, which is used as an input both in the production of final output and in the production of new public capital. On the one hand ,public...

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 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...
