Bean Impact Study

Principal Investigator



New varieties of beans are ongoingly being developed through public investments in bean breeding research in Central America and the USA. This project focuses on estimation of the economic impact of these investments, specifically on extending previous estimates of impact studies conducted in the last 10-15 years. Using new tools such as DNA fingerprinting the study will reduce misidentification and generate more accurate estimates for decision-makers, breeders, and development organizations.


  • To estimate the impact of the adoption of improved bean varieties in Guatemala, Honduras, Nicaragua and Haiti, and the state of Michigan in the US.
  • To look for insights on models of scaling up that have been applied in increasing the adoption of improved bean varieties in Central America and public varieties in Michigan.
