More Power to the Pill: The Impact of Contraceptive Freedom on Women's Life Cycle Labor Supply

Introduction

  • The introduction of Enovid, the first birth control pill, in 1960 allowed U.S. women significant freedom to plan childbearing and careers.
  • Research uses variation in state consent laws to examine how access to the pill affected timing of first births and women's labor force participation.
  • Findings suggest legal access to the pill before age 21:
    • Reduced likelihood of first birth before age 22.
    • Increased participation in the paid labor force.
    • Increased annual hours worked.

Historical Context

  • Margaret Sanger, founder of the birth control movement, argued for its future influence.
  • Enovid's release impacted women's marriage age and participation in professional jobs.
  • Prior studies: Birth control had limited effect on fertility and labor market participation (Becker's view).
  • Pill's introduction coincided with social movements and changes such as the Civil Rights Movement and Vietnam War.

State Consent Laws and Pill Access

  • State legal changes from 1960 to 1976 allowed unmarried women under 21 to consent to medical care, facilitating pill access.
  • Changes were part of broader shifts in legal rights for minors.
  • Analysis uses these legal changes to examine pill's impact on fertility and labor market behavior.

Empirical Findings

  • First birth rates declined significantly for 18-19 year olds after pill introduction.
  • Declines in early childbearing closely follow pill diffusion.
  • Women born around 1955 benefited from early access to the pill, delaying first births beyond age 22.
  • Labor force participation increased significantly among cohorts with pill access.

Impact on Women's Labor Participation

  • Pill access led to substantial changes in labor force participation for women aged 26-30:
    • 24 percentage points higher participation at age 25 compared to pre-pill cohorts.
  • Early access affected work behavior through birth timing.
  • Pill allowed women to delay childbearing, pursue education, and develop careers.

Methodology

  • Analysis uses CPS data, focusing on women born from 1940-1955.
  • Legal access to the pill is linked to significant labor supply changes.
  • Methods used account for other factors like abortion access and demographic characteristics.

Conclusions

  • The pill had a profound impact on women's economic roles by enabling better fertility control.
  • It allowed women to plan births around educational and career goals, increasing labor market participation.
  • Provides evidence for the pill's role in women's economic empowerment and offers insights into broader societal shifts.
