Question: One of the side-benefits of expanding education can be an increase in equity or, at least, no strong increase in inequality. Extending primary and secondary education to all residents of a country contributes to individual productivity and individual incomes and may be important in creating a regime for shared growth. Compare enrolment rates and income inequality for five less-developed nations (use the ratio of income of the top 20 percent of income earners to the bottom 20 percent of income earners, or the Gini coefficient, as the measure of inequality). Do countries with lower enrolment coverage for primary and secondary education have more or less inequality than economies with higher enrolment ratios? Are there any systematic differences amongst the countries you have selected? Why, or why not? What other factors might be at work which contribute to or detract from the possibility for shared growth?
