+  A study on the effects of the introduction of legal access to contraceptive measures for women in the United States, measuring the impacts on closing the gender gap through the gendered hourly working wage distribution.
+  The study finds that of the closing gender pay gap from 1980 to 2000, legal access to 'the pill' as contraceptive from an early age contributed by nearly percent in the 1980s and over 30 percent in the 1990s.
+  Thus, overall the authors estimate that nearly one third of total female wage gains during this time were attributable to legal access to contraception.
+  The primary channels identified are greater educational attainment, occupational upgrading, and increased labour market experience made possible due to no early exit.
+  The authors also argue that the pill spurred individual agency to invest in personal human capital and career.
+  However, there are some limitations to the findings: The dataset cannot capture specific access to contraception beyond age 20, which makes the window of analysis more restricted and especially focused on the segment of women under 21.
+  Additionally, the study can not control for social multiplier effects such as employers reacting with changed hiring or promotion patterns or expectations about marriage and childbearing, as well as the overall coinciding paradigmatic change in norms and ideas about women's work and end of the national baby boom.
