In this model of North and South economies, growth is driven by Schumpeterian R&D and by accumulation of two types of human capital, versatile and specialized. The former is school intensive while the latter is on-the-job-training intensive. Growth is endogenous and independent of scale effects....

During the last twenty years the share of researchers in the workforce has been rising in OECD countries. The consistency of this pattern suggests that it is not a transitional phenomenon. This paper demonstrates that the rise of research can occur in the steady state when schooling inequality...

Is it possible that relying too heavily on natural resources affects saving and investment in a way that hampers economic growth? – and thus, in the long run, the level of output per capita. This paper reviews the literature, explores the data and compares and contrasts the explanatory power...

This paper analyzes the mechanisms, other than market size, through which international trade of intermediate goods incorporating state-of-the-art technological knowledge affects accumulation of human capital and wage inequality in the North and South. Under North-South technological diffusion,...

The paper develops a two-country dynamic general-equilibrium model of growth without scale effects to explore the effects of globalization on long-run growth and wages. Higher quality products are endogenously discovered through stochastic and sequential global innovation contests in which...

This paper presents an endogenous growth model where, in line with the recent empirical evidence, the telecommunications industry (telecom) is an engine of growth. In such a framework, this paper analyzes the channels through which telecom contributes to economic growth and focuses on market...

Growth accounting exercises point to aggregate TFP differences as the dominant source of the large cross-country income differences. In this paper, I ask which sectors account for the aggregate TFP gap between rich and poor countries. Data limitations for developing countries have led...

We investigate, both theoretically and quantitatively, a previously unexplored link between adult mortality and growth. Our mechanism allocates a central role to individuals as carriers of useful ideas and to personal contact as an important means of passing on the useful ideas to future...
