Women’s agency—their ability to define and act on goals, make decisions that matter to them, and participate in the economy and public life (Donald et al. 2017; Kabeer 1999; Laszlo et al. 2017)—is limited in many contexts around the world. J-PAL’s literature review, “What works to enhance women’s agency,” draws from 160 randomized and natural experiments in low and middle-income countries to distill key lessons on what we know about supporting women’s agency based on quantitative evidence. This review takes a cross-cutting approach to analyzing evidence across different domains of women’s agency and focuses on understanding the mechanisms through which interventions achieve their impacts.
