英文文献：A Technical Efficiency Analysis Of Pennsylvania Dairy Farms
英文文献作者：Wang, Qiuyan
英文文献摘要：
This study estimates technical efficiency (TE) using a stochastic production frontier based on a randomly selected cross-sectional sample of Pennsylvania dairy farms. The Cobb-Douglas functional form is a suitable model in the estimation. Estimates of mean technical efficiency and appropriate technical efficiency of individual farms are computed and compared under three distributional assumptions of the efficiency disturbance terms. Maximum likelihood techniques are used for the estimation of the stochastic frontier. The technical efficiency measure is further broken down by different farm size.
