Though promising, these studies may fail to correctly identify causality and
may not be replicable for all countries. The authors conclude there is no “one-
size– ts- all” answer to engineering educational attainments across all nations.
Boxed Examples
Box 8–1: Estimating Rates of Return from Wage Equations
Box 8–2: Returns to Schooling and Income Opportunities
Box 8– 3: Mexico’s Programa de Educación, Salud y Alimentación
(Progresa)/ Oportunidades
There are three boxed examples in this chapter. The rst case study shows how
rates of returns are econometrically estimated through wage equations and points
out the number of assumptions and pitfalls when making these calculations. The
second study outlines recent research by Foster and Rosenzweig, who nd that
schooling has returns primarily when new income- generating opportunities arise.
The third case study provides a summary of the well- known PROGRESA pro-
gram from Mexico. This program introduced a set of conditional cash transfers to
poor families if their children were enrolled in school and family members visited
health clinics for checkups.
In the New Edition
This chapter has been revised and updated from the sixth edition, and bene ts from
recent revisions to the Barro- Lee data set on school attainment and from recent
results of the Organisation for Economic Co- Operation and Development (OECD)’s
Programme for International Student Assessment (PISA). Fuller use is made of
econometric approaches, including natural experiments and randomized controlled
trials (RCTs) in determining rates of return to schooling and the effectiveness of
alternative interventions to improve learning outcomes.
Class Notes
In terms of technical analysis, this is an easy chapter for students. It is helpful to
highlight the concept of education as investment in human capital and demon-
strate that education can be a matter for economic analysis like any other policy
decision affecting investment and resource allocation. Scarcity and the need to
choose ef ciently are hard realities that poor countries can ill afford to neglect
when considering costly education decisions. In this regard, the divergence between
private and social rates of return on education is of major importance. You can
explain the issue neatly using supply– and- demand analysis, augmented to show
externalities and subsidies.
The application of cost– bene t analysis to evaluating education investment is
the analytical crux of Chapter 8. You can cover this material at a broad intuitive
