Productivity Growth in German Dairy Farming using a Flexible Modelling Approach
采用随机系数产出距离函数，测量并分解德国奶牛养殖业的生产率增长，发现年均全要素生产率增长率为1.1%，技术进步是主要驱动力。
Abstract A random‐coefficients specification of an output distance function is used to measure and decompose productivity growth in German dairy farming. This specification can accommodate heterogeneity with respect to the technology employed by dairy farms, allowing for specialised and non‐specialised farms to be included in the analysis. The proposed modelling approach is favoured by the data when compared with the conventional translog specification of distance functions. The average total factor productivity growth rate for German dairy farms is estimated at 1.1%, with the technical progress component contributing most of this growth.
