Paul Romer’s paper Increasing Returns and Long Run Growth, now 15 years old, led to resurgence in the research on economic growth. Since then, growth literature has expanded dramatically and has shifted the research focus of many generations of macroeconomists. The new line of work has...

This paper examines the robustness of explanatory variables in cross-country economic growth regressions. It employs a novel approach, Bayesian Averaging of Classical Estimates (BACE), which constructs estimates as a weighted average of OLS estimates for every possible combination of included...

In this paper we construct a set of human capital indexes for the states of the United States for each Census year starting in 1940. In order to do so, we propose a new methodology for the construction of index numbers in panel data sets. Our method is based on an optimal approach by which we...

We construct a set of human capital indexes for the states of the United States for each census year starting in 1940. To do so, we propose a new methodology for the construction of index numbers in panel data sets. Our method is based on an optimal approach by which we choose the "best" set of...

We analyze the steady state and transitional dynamics of two-sector models of endogenous growth. The necessary conditions for endogenous growth imply that transitions depend only on a measure of the imbalance between the two sectors such as the ratio of the two capital stocks. We use the...

We estimate the World Distribution of Income by integrating individual income distributions for 138 countries between 1970 and 2000. Country distributions are constructed by combining national accounts GDP per capita to anchor the mean with survey data to pin down the dispersion. Poverty rates...

We construct a model that combines elements of endogenous growth with the convergence implications of the neoclassical growth model. In the long run the world growth rate is driven by discoveries in those economies that lead in their use of technology. Followers converge towards leaders because...
