This paper explains why different studies present widely-varying estimates of the effect of increased schooling on national income. It shows that when correctly-interpreted, these studies support the hypothesis that a one-year increase in average schooling attainment raises national income...

I estimate a Solow model augmented with human capital in 42 countries for 1910-2000. Estimated TFP growth is 0.3%/year, and the steady-state rate for GDP/capita is 1.0%/year. Implicitly for high-income countries maintaining growth above this rate will be increasingly difficult.

I use a dynamic augmented Solow model to estimate the effects of students’ test scores and investment in schooling on economic growth rates in 49 countries during 1985-2005. In the complete data set, either average test scores or investment in schooling explain economic growth rates, and more...

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...

In 1960 Theodore Schultz expounded a human capital theory of economic growth that includes three elements: 1) Countries without much human capital cannot manage physical capital effectively, 2) Economic growth can only proceed if physical capital and human capital rise together, and 3) Human...

Using a dynamic augmented Solow model, I estimate the effect of students’ schooling attainment, schooling expenditures, and students’ test scores on growth rates over the period 1985-2005. I also estimate the effect of related measures for human capital stocks on national income in a static...

Lower ICP 2005 construction prices in developing countries increase the effect of capital on output in PWT 7.1 and 8.0 and cause negative world TFP growth during 1990-2010 in PWT 8.0. The investment data appear to be more accurate in PWT 6.3.

We estimate the direct and external effects of levels of schooling on personal income in Ecuador in 2011, using data for 69,653 individuals in 567 municipalities. Using a Mincerian model that includes municipal levels of schooling and the size of the municipality and controls for endogeneity, we...
