His research examines: impacts on deforestation of roads, protected areas and ecopayments (Brazilian Amazon, Costa Rica, Bolivia, Peru, Mexico); influences on harmful exposures (stoves in China & Pakistan, groundwater arsenic in Bangladesh); responses to climate and water shocks in production or in water bargaining (NE Brazil, Colombia); and how U.S. regulators might shift the incentives for firms to self-audit and provide information. This applied research aims to raise the chance that interventions have their intended impacts upon the environment and natural resources, while helping people and groups they are designed to help.
