The paper examines the effect of heterogeneity in individual human capital formation on cross-country income inequality. It considers a two-country model of overlapping generation heterogeneous economies with the following features: (1) individuals are heterogeneous with respect to inborn...

The paper studies the effects of cross-country differences in the production process of human capital on income distribution and growth. Our overlapping gen- erations economy has the following features: (1) consumers are heterogenous with respect to parental human capital and wealth; (2)...

How does risk or uncertainty in the productivity of research affect the growth rate of the economy? To answer this question, a model of endogenous technological change is used where sustained growth stems from intentional investments in R&D from profit-maximizing firms. The uncertainty arises...

The strategic choices regarding innovation and R&D policy in Portugal have, over the last two decades, produced various positive benefits, in which particularly the regions of Lisbon and Algarve have taken the lead. These are the only parts of the country that converge towards the European...

Evolutionary and environmental economics have a potentially close relationship. This paper reviews past and identifies potential applications of evolutionary concepts and methods to environmental economics. This covers a number of themes: resource use and ecosystem management; growth and...

The analysis in this paper shows that unpredictable variations in economic productivity may have a positive or negative effect on the average growth rate of output. This theoretical ambiguity result is not solely determined by the value of the elasticity of intertemporal substitution (of...
