We study the competitive equilibria of a two-country endogenous growth model in which the source of growth is the linearity of technology in reproducible inputs. We begin by showing that in a model with no externalities there is a unique equilibrium; however, there are multiple ways in which the...

In an attempt to account for the huge observed disparity in international incomes, several recent papers study models in the spirit of Solow (1960) where the adoptions of better technologies require investments in new equipment. This paper continues this line of research. It describes an economy...

In this paper, we argue that the case for universal compulsory education for sub-Saharan Africa might have been overstated. We capture the African situation through a heterogeneous-agent model, in which high costs of education relative to income and the skill premium cause the economy to...

This paper investigates whether technological shocks, constructed to be consistent with the observed cross-country income dispersion, are also capable of accounting for development regularities related to capital accumulation. This question is approached via a quantitative theoretical analysis...

This paper analyzes optimal foreign aid policy in a neoclassical growth framework with a conflict of interest between the donor and the recipient government. Aid conditionality is modeled as a limited enforceable dynamic contract. We define the contract to be self-enforcing if, at any point in...

This paper presents evidence that the spread between the marginal product of capital and the return on financial assets is mich higher in poor than in rich countries. A model with costly intermediation is developed. In this economy, individuals choose at each instant whether to work or to...

Is there a trade-off between fluctuations and growth? The empirical evidence is mixed, with some studies finding a positive relationship, while others find a negative one. Our objectives are to understand how fundamental uncertainty affects the long run growth rate and to identify important...

Can the initial distribution of land, in a country's early history, affect its subsequent economic development? In this paper, I show that when land ownership is sufficiently concentrated, the landed elite will lobby the government to raise barriers to industrialization in order to protect its...

We present an endogenous growth model where innovations are factor saving. Technologies can be changed paying a cost and technological change takes place only if the benefits are larger than the costs. Since the gains derived from factor saving innovations depend on factor abundance, biased...

Abstract: The long-run growth model of Galor and Weil (AER 2000) is examined quantitatively. We first give parametric forms to some functions which were only given on general form in the original article. We then choose numerical parameter values in line with calibrations of related long-run...
