"Transgender Transitioning and Responsiveness to Policy: Evidence from the Netherlands" with John Cawley and Hans van Kippersluis
American Economic Association: Papers and Proceedings, 114: 364-68. [code]
Abstract: This study examines a 2014 policy change in the Netherlands that simplified the process to legally transition one’s gender. Administrative data for 2006-22 indicate there was a 725% increase in transitions after the policy change, suggesting that legal gender transitions are elastic to costs and barriers. The policy change was followed by a 10-year reduction in the average age at transition, and a reduction in the use of gender-affirming care in the 3 years prior to transitioning. This research sheds light on how policy changes can influence decisions related to gender transitioning and the use of gender-affirming care.
