We use data from a lab-in-the-field experiment in Uganda to examine the effect of empowering girls on their brothers’ competition preferences. Our identification strategy exploits random assignment of a girls’ empowerment intervention across communities and natural variation in sibling sex composition. We find that empowering girls significantly increases their brothers’ competitiveness. The results suggest that competition preferences are malleable and that programs targeting girls can have spillovers to their brothers.
