Alex Pfaff is a Professor of Public Policy, Economics and Environment. Trained as an economist, he is focused on how the environment and natural resources, economic development, and a range of policies influence each other. Research accessible at AlexPfaff.comHe has studied: impacts on forests of protected areas, incentives, roads, railroads and concessions/certification (Brazil’s Amazon, Costa Rica, United States, Panama, Madagascar, Mexico, Peru, Cameroon, Bolivia); institutional responses to water shocks (Brazil’s Northeast, Colombia, Mexico); drivers of harmful exposures (groundwater arsenic in Bangladesh, stove emissions in China & Pakistan); and incentives for firms to self-audit and disclose (United States). This applied research aims to increase the chance that policies have their intended impacts upon not only the environment but also the people affected.
