Why doesn’t capita flow to developing countries as predicted by the neoclassical model? Is the explanation simply that cross-country marginal productivity of capital (MPK) is equalized, and if so, why? We revisit these issues by unpacking MPK into its public and private components, since there...

We propose an economic theory of infectious disease transmission and rational behavior. Diseases are costly due to mortality (infected individuals can die prematurely) and morbidity (lower productivity and quality of life). Our model offers three main insights. First, a greater prevalence of...

This paper shows, within a Heckscher-Ohlin version of the two-sector neoclassical growth model, that land, besides having long-run effects, is also a main determinant of the speed of convergence toward the steady state when there are cross-sector capital share differences. This result stands in...

This paper examines two related questions: what effects do infectious diseases exert on growth and development, and are they quantitatively important? We present evidence on the effect of health and infectious diseases on economic development using Hansen’s (2000) endogenous threshold...

This paper compares transitional dynamics in two alternative R&D non-scale growth models, one includes endogenous human capital, whereas the other does not. We show that focusing on the speed of convergence to discriminate between the two models can be misleading. Our analysis suggest that a...
