Evaluating Value Chain Interventions: A Review of Recent Evidence

This ILRI discussion paper reviews 20 value chain interventions and discusses the econometric techniques used to address the validity of findings. It explores the use of propensity score matching, instrumental variables, difference in difference, regression discontinuity, and randomized controlled trials. Qualitative and participatory methods are also examined with the idea that they may be able to better capture the complexity of value chain processes.
