We extend the structural gravity model to identify external economies or diseconomies of scale elasticities of cross-border trade. We find statistically and quantitatively significant economies of scale in cross-border trade in 5/8ths of sector-direction cases for Canadian provinces while 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...

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, we can observe an ambiguous effect of population growth on economic growth, as empirical evidence...

A consensus in the growth literature is that scale effects of R&D are non-existent across mature industrialized economies. However, the scrutiny across emerging economies is lacklustre at best. The empirical studies of scale effects also leave the issues of unbalanced regression (non-standard...

There has been a concomitant rise in R&D and the rate of economic growth in emerging countries. Analyzing a panel of 31 emerging countries, we find convincing evidence of scale effects which make government policies potent for long-run growth. This contrasts sharply with the well known findings...

Returns to scale to capital and the strength of capital externalities play a key role for the empirical predictions and policy implications of different growth theories. We show that both can be identified with individual wage data and implement our approach at the city-level using US Census...

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...
