Targeting, bias, and expected impact of complex innovations on developing‐country agriculture: evidence from Malawi

Beliyou Haile, Carlo Azzarri, Cleo Roberts, David J. Spielman · 2016 · Agricultural Economics

Summary. A participatory action research program in Malawi tested agricultural technologies with smallholder farmers to reduce poverty and improve food security. The study found that better-off farmers were systematically selected to test innovations, creating bias. After accounting for observable differences, early results showed positive effects on maize yield and harvest value, but selection bias from unobservable factors remained a concern. The authors recommend improving program design and targeting criteria to enhance external validity.
