Dairy Farm Efficiency Measurement Using Stochastic Frontiers and Neoclassical Duality
基于Kopp和Diewert的确定性方法，构建随机效率分解模型，分析新英格兰奶牛场的技术、经济和配置效率，发现平均经济效率约70%，技术效率（83.0%）与配置效率（84.6%）差异不大，且农场规模、教育、推广和经验对效率影响不显著。
Abstract This paper presents a stochastic efficiency decomposition model based on Kopp and Diewert's deterministic methodology. The stochastic model is used to analyze technical, economic, and allocative efficiency for a sample of New England dairy farms. The results suggest that mean economic efficiency for the farmers in the sample is about 70% and that, on average, there is little difference between technical (83.0%) and allocative (84.6%) efficiency. Analyses of the relationship between efficiency and four socioeconomic variables—farm size, education, extension, and experience—reveal that, despite some statistically significant associations, efficiency levels are not markedly affected by these variables.
