Impact Assessment of Technologies That Mitigate Adverse Circumstances: The Case of Disease-Resistant Beans in Honduras


  • Mather, David
  • Oehmke, James F.


Constructing appropriate counterfactual scenarios is an ongoing challenge for impact assessment of agricultural research. Using farm-level survey data from Honduras, this paper adapts the Heckman two-step procedure to construct the counterfactual to resistant variety (RV) bean yields by predicting imputed traditional variety yields of RV users.
