Did progresa reduce inequality of opportunity for school reenrollment?

The school reenrollment probability conditional on a child's circumstances (gender, indigenous origin, and family background) is our measure of a child's school reenrollment opportunity. For children who completed grades 1-6, we use generalized Lorenz and Lorenz dominance to show that Progresa improved aggregate opportunities and reduced inequality of opportunity. Moreover, using the human opportunity index-or, alternatively, a Gini opportunity aggregator-we show that the decrease in inequality of opportunity accounts for about 15%-40% of the total effect of the program on aggregate opportunities.
