This article presents revised estimates of the external rates of return on investment in schooling provided in “Schooling and National Income: How Large Are the Externalities?” The analysis is based on data for the same set of countries, but it incorporates methodological improvements that...

This paper uses a new data set for cumulative national investment in formal schooling and a new instrument for schooling to estimate the national return on investment in 61 countries. These estimates are combined with data on the private rate of return on investment in schooling to estimate the...

The marginal product of human capital in Mankiw, Romer, and Weil's [1992] augmented Solow model measures the direct and two external effects of human capital created from schooling on national income. If this model is valid, its estimates of the share of this marginal product accruing to workers...

A review of the measures of the stock of human capital used in empirical growth research reveals that human capital is mostly poorly proxied. The simple use of the most common proxy, average years of schooling of the working-age population, misspecifies the relationship between education and the...

The defense-growth nexus is investigated empirically using longitudinal data for Guatemala and allowing the effect of defense spending on growth to be nonlinear. Using recently developed econometric methods involving threshold regressions, evidence of a level-dependent effect of military...
