We develop and estimate a model based on a common technology but different farmer's perceptions of cost and returns to different input-output combinations, in which such perceptions are modeled as latent variables with multiple indicators. We hope to advance knowledge both with respect to substantive issues of agricultural development policy, and with respect to methodological issues concerning the estimation of mult-input/multiproduct production functions in which many input/output combinations are unused and in which, for various reasons, price data do not exist for outputs not produced of for inputs not usedAgricultura - tecnologia - adocao - Brasil - zona da mata; Agricultura - desenvolvimento; Producao - tecnicas - homogeneidade.1 aNERLOVE, M.1 aSICKLES, R.
