We study if prior exposure to one environmental health technology - improved sanitation - complements or substitutes for additional household investments in another such technology -- an electric induction cookstove. A cookstove demand revealing auction took place over a decade after a random...

Highly advanced, community-level drinking water treatment facilities are increasingly seen as water supply solutions in locations where piped in-house water systems are nonexistent or unreliable. These systems utilize combined technologies, such as advanced filtration plus ultraviolet...

Interventions in remote, rural settings face high transaction costs. We develop a model of household decision-making to evaluate how non-governmental organizations (NGOs) address these implementation-related challenges and influence intervention effectiveness.
