Both individuals and countries benefit from women's education. Individuals who invest in education receive a net monetary gain over the course of their lifetime.[5] According to Harry Patrinos, lead education economist at the World Bank,[7] “the profitability of education, according to estimates of private rate of return, is indisputable, universal, and global.”[6] The principle holds particularly for women, who can expect a 1.2% higher return than men on the resources they invest in education.[5] Providing one extra year of education to girls increases their wages by 10-20%.[8] This increase is 5% more than the corresponding returns on providing a boy with an extra year of schooling.[8]
