【 摘 要 】

Understanding the trade-offs inimproving the precision of agricultural measures throughsurvey design is crucial. Yet, standard indicators used todetermine program effectiveness may be flawed and at adifferential rate for men and women. The authors use ahousehold survey from Mozambique to estimate the measurementerror from male and female self-reports of their adoptionand knowledge of three practices: intercropping, mulching,and strip tillage. Despite clear differences in human andphysical capital, there are no obvious differences in theknowledge, adoption, and error in self-reporting between menand women. Having received training unanimously lowersknowledge misreports and increases adoption misreports.Other determinants of reporting error differ by gender.Misreporting is positively associated with a greater numberof plots for men. Recall decay on measures of knowledgeappears prominent among men but not women. Findings fromregression and cost-effectiveness analyses always favor thecollection of objective measures of knowledge. Given thelowest rate of accuracy for adoption was around 80 percent,costlier objective adoption measures are recommended for asubsample in regions with heterogeneous farm sizes.
