Just-Pope production functions have been traditionally estimated by feasible generalized least squares (FGLS). This paper investigates the small-sample properties of FGLS and maximum likelihood (ML) estimators in heteroscedastic error models. Monte Carlo experiment results show that in small...

Expected effects from partially lifting tariff barriers on the Mexican agricultural sector are investigated using a restricted profit function (RPF) approach. Short-run and intermediate-run effects of the implementation of GATT minimum tariff provisions on Mexican agricultural trade are...

Income differences attributed to differential access to water in irrigation systems are common. Prior studies of farm-level water use in developing areas have typically been limited to using number of irrigations as a proxy for water use. We develop a volumetric measure in Sri Lanka's Kirindi...
