Jenny C. Aker: It’s all fun and games? Using WTP Experiments for Longer-Term Impacts

This paper tests whether Becker-DeGroot-Marschak (BDM) experiment can generate sustained impacts on adoption and usage of an improved storage technology. Using a randomized control trial (RCT), we find that WTP for the technology is lower than the market price, with no differential effects by gender or region. Short-run treatment effects on adoption and usage are positive. Almost two years after the experiment, we find persistent effects on adoption, usage, and storage behavior, as well as reduced use of pesticides and improved self-reported health outcomes. These results suggest that simple experiments can lead to sustained improvements in technology adoption, primarily by allowing households to experiment with the technology.
