This study examines the five-year impacts of a bicycle distribution program for adolescent girls
in rural Zambia, implemented across 100 schools as part of a randomized controlled trial. While the
program increased girls’ self-reported empowerment and reduced experiences of domestic and intimate
partner violence, it also led to higher rates of early marriage - an outcome that runs counter to
the program’s initial objectives. We explore mechanisms behind this paradox, including improved
socioeconomic status, food security, and increased receipt of bride prices, which may reflect girls’
higher perceived value in the marriage market. Our findings suggest that girls exercise greater
agency by making strategic decisions to secure higher-quality unions on the local marriage market.
Our results underscore the complex interplay between empowerment, economic mobility, and local
norms, and highlight the importance of accounting for potential unintended consequences when
designing gender-focused development interventions.
