The P3 project was launched in 2015 through a collaboration among Colorado University, the NHRC, and North Carolina State University. The central aim of the P3 project is to study factors influencing adoption of improved cookstoves in Northern Ghana. Specifically, we look at how economic incentives, social learning, and subjective beliefs interact to influence technology adoption dynamics. We also examine supply-side factors limiting or facilitating expanded access to cleaner stoves in the study region. This involves field experiments in both rural and urban areas of the Kassena-Nankana Districts, using improved biomass and liquefied petroleum gas (LPG) stoves. Results will inform dissemination of clean cookstoves and other technologies beyond the study area. The P3 project is funded by grants from the NSF Economics program, the NIH Clean Cooking Implementation Science Network, and a gift from the Rathmann Family Foundation.
