"Birth Control Access Boosts Women's Wages, Study Finds" - Huffington Post. 03/26/2012.
A study by Martha Bailey and colleagues has found that women with access to birth control pills in the 1960s and 1970s earned an average 8% more than women without access by the 1980s and 1990s. Bailey says: "As the pill provided younger women the expectation of greater control over childbearing, women invested more in their human capital and careers."
