This document summarizes a study that tested how different design attributes of agricultural extension video campaigns in Uganda impacted their effectiveness and inclusiveness. Specifically, it varied the gender of the messenger (male, female, or couple) and recipient (male, female, or couple). The study found that reducing information asymmetry between household members by targeting couples, promoting a cooperative approach through couple messengers, and leveraging gender homophily all led to more joint decision-making, technology adoption, and productivity. The low-cost video interventions showed high returns, demonstrating the potential of design attributes to make agricultural extension more inclusive and impactful.
