We revisit the issue of self-fulfilling “waves of enthusiasm” as stationary rational expectations equilibrium outcomes in endogenous-growth models that merge the quality-ladders with the expanding-variety mechanism. By considering a lab-equipment specification with vertical-innovation...

This paper studies the firm size distribution arising from an endogenous growth model of quality ladders with expanding variety. The probability distribution function of a given cohort of firms is a Poisson distribution that converges asymptotically to a normal of log size. However, due to firm...

This paper re-examines the role of physical capital accumulation in the Indian economy over the period 1953-2010. As an alternative to the orthodox total factor productivity (TFP) view, the paper develops a combined TFP-capital accumulation hypothesis of growth transitions. The results show that...

By means of an endogenous growth model of directed technical change with vertical and horizontal R&D, we study a transitional-dynamics mechanism that is consistent with the changes in the share of the high- versus the low-tech sectors found in recent European data. Under the hypothesis of a...

We develop an extended directed technological change model with R&D driven growth to analyze the growth rate, technological-knowledge bias, skill premium and industrial structure, assuming: (i) complementarities between intermediate goods in production, and (ii) internal costly investment. We...

This paper builds an endogenous growth model of directed technical change with vertical and horizontal R&D and scale effects at the industry level to study an analytical mechanism that is consistent with the observed cross-country pattern in the skill structure, the technology structure and...

Based on an extended model of endogenous directed technical change and on cross-country data, we identify and quantify the long-run link between: (i) the technology structure (high- versus low-tech sectors) and the skill structure (high- versus low-skilled workers), by considering an explicit...

This paper presents an endogenous growth model of directed technical change with vertical and horizontal R&D to study an analytical mechanism that is consistent with the coexistence of aggregate stability and structural change. We focus on changes in the share of the high- versus the low-tech...

In what form should the Intellectual Property Rights (IPR) be treated in an endogenous growth model? What are the effects of introducing IPR into a North-South endogenous growth model? In this paper, we develop a general equilibrium endogenous growth model that emphasizes the IPR enforcement...

This paper develops a tournament model of horizontal and vertical R&D under a lab-equipment specification. A key feature is that the overall growth rate is endogenous, as the splitting of the growth rate between the intensive and the extensive margin is itself endogenous. This setup gives rise...
