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.

PWT 7.0 data deviate substantially from PWT 6.3 data because the benchmarked prices for 1970 to 1996 used in PWT 6.3 were entirely discarded. PWT 7.0 data are unreliable and appear to be much less accurate than PWT 6.3 data.

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...

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 challenges Hanushek and Woessmann's (2008) contention that the quality and not the quantity of schooling determines a nation's rate of economic growth. I first show that their statistical analysis is flawed. I then show that when a nation's average test scores and average schooling...

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...

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...
