The main objective of this paper is to outline the relevance of regional externalities when explaining growth. The recent literature has already put attention to external economies or spillover effects, although in most cases it has been at firm or sectoral level. However, it is our belief that...

This paper tests whether Spanish industry adjusted the amount of inputs and output to those considered optimal given their prices in each time period. With this aim, we use the short- and long-run equilibrium models given by duality theory, and we apply the optimality tests derived from them for...

This paper provides novel empirical evidence of the indirect effect of educational attainment on regional economic growth, through its influence on the profitability of investment in physical capital. We test the hypothesis that the regional heterogeneity of the return to physical capital can be...

This paper investigates the extent to which the gap in total factor productivity between small and large firms is due to differences in the endowment of factors determining productivity and to the returns associated with these factors. We place particular emphasis on the contribution of...

Empirical evidence is compelling that large firms are more productive than small firms. The hypothesis in this paper is that the productivity differences between small and large firms are associated with two of the main determinants of a firm’s performance: the human and technological capital...

The direct effect of human capital on economic growth has been widely analysed in the economic literature. This paper, however, focuses on its indirect effect as a stimulus for private investment in physical capital. The methodological framework used is the duality theory, estimating a cost...
