TL;DR: In this paper, the authors discuss methodological issues surrounding those estimates and confirm that primary education continues to be the number one investment priority in developing countries, and also show that educating females is marginally more profitable than educating males, and that the academic secondary school curriculum is a better investment than the technical/vocational tract.

TL;DR: In the 40-plus year history of estimates of returns to investment in education, there have been several reviews of the empirical results in attempts to establish patterns as discussed by the authors, and many more estimates from a wide variety of countries, including over time evidence, and estimates based on new econometric techniques, reaffirm the importance of human capital theory.

TL;DR: In the 40-plus year history of estimates of returns to investment in education, there have been several reviews of the empirical results in attempts to establish patterns as mentioned in this paper, and many more estimates from a wide variety of countries, including over time evidence, and estimates based on new econometric techniques, reaffirm the importance of human capital theory.

TL;DR: In this paper, the authors updated evidence on the returns to investment in education by adding estimates for new countries and refining existing estimates to bring the total number of country cases to over 60 and confirm earlier patterns, namely, that returns are highest for primary education, the general curricula, the education of women, and countries with the lowest per capita income.

TL;DR: In this article, the authors make planners and policymakers more aware of the problems that can arise in developing investment strategies for education and the analytical tools and information that are available to help solve them.
