Employing cross-country data, this paper evaluates the transitional dynamics predictions of a non-scale growth model of endogenous technology innovation and imitation. We show that, unlike the neoclassical growth framework, the transitional dynamics of the R&D-based growth model can account for...

This is a model of technology adoption that takes seriosly the fact that new inventions are specific to the enviromment in which they emerge. The key feature of the model is that the firm can invest resources in R&D to adapt externally originated ideas to the environment in which they are used....

We study the dynamics of poverty and health in a model of endogenous growth and rational health behavior. Population health depends on the prevalence of infectious diseases that can be avoided through costly prevention. The incentive to do so comes from the negative effects of ill health on the...

This paper searches for the determinants of government-funded R&D. The goal is to disentangle whether the efficiency considerations overwhelmingly emphasized by the theoretical literature are indeed the main driving force behind public R&D expenditures. Another goal of the paper is to assess...

Why are some countries mired in poverty and ill health? Can policy facilitate their transition to sustained growth and better living standards? We offer answers using a dynamic model of disease and development. Endogenous transmission of infectious disease generates non-ergodic growth where...

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...

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...
