The Power of Lakshmi
研究印度Dhanlakshmi有条件现金转移计划对出生性别比的影响，发现该计划显著改善了女婴出生比例，且对生育率影响较小，同时提升了免疫和教育等产后指标。
<h3>Abstract</h3> Worldwide, 1.6 million girls are “missing” at birth every year. One policy tool to improve the sex ratio is a conditional cash transfer that pays parents to invest in daughters, but existing evidence on their effectiveness is sparse. Using a difference-in-differences framework, we evaluate the Dhanlakshmi scheme, an Indian CCT program that strongly encouraged girl births without restricting fertility. Dhanlakshmi improved the sex ratio at birth, with only a small fertility increase. The girl-birth effect was concentrated among the first two parities and partially persisted after the program was discontinued. Post-birth outcomes like immunization and education also improved.
