对规模收益的准确估计要求投入和产出的计量准确无误，并考虑到不同规模企业之间的环境和管理差异。影响农业规模收益估计的计量问题包括：（1）将农场住宅与资本投入相结合，（2）环境和管理特征与规模的相关性，以及（3）非农就业对小农场产出和生产成本的影响。对玉米带农场长期平均总成本曲线的估计表明，在考虑上述因素后，农业的规模经济消失，而随着农场规模的增加，有证据表明不经济。
Accurate estimates of returns to scale require that inputs and output are measured without error and that environmental and managerial differences among firms of varying sizes are taken into account. Measurement problems affecting estimates of returns to scale in agriculture include: (1) combining the farm dwelling with capital inputs, (2) correlation of environmental and management characteristics with size and (3) the effect of off-farm employment on small farm output and production costs. Estimates of long run average total cost curves for farms in the corn belt reveal that after the above factors are taken into account, estimated scale economies in agriculture disappear, while there is evidence of diseconomies as farm size increases.
