This title presents a method of establishing the economic returns to investments in school quality. While economists have long had methods to estimate rates of return to additional years of schooling, until now there have not been similar methods for analyzing returns to investments in school quality. Empirical work using data from Ghana shows that investments in school quality have higher rates of return than investments in increased years of schooling. The bulk of the study is written by Paul Glewwe, with some co-authored and contributed pieces from his co-researchers.
