Mismeasurement and efficiency estimates : Evidence from smallholder survey data in Africa por Abay, Kibrom A., Wossen, Tesfamichael, Chamberlin, Jordan

“…We show theoretically that non-classical measurement error introduces multiple identification challenges and sources of bias in estimating smallholders' technical inefficiency. We then empirically examine the implications of measurement error for the estimation of technical inefficiency using smallholder farm survey data from Ethiopia, Malawi, Nigeria and Tanzania. …”
