Parametric Approaches to Productivity Measurement: A Comparison among Alternative Models
用多种参数模型灵活测量全要素生产率增长，分解其成分，并以瑞典水泥行业数据检验各模型估计的异同，发现结果高度依赖模型选择。
This paper deals with modeling total factor productivity (TFP) growth in a flexible manner using panel data. Several competing parametric models are used to explore whether there are any similarities in the estimates of TFP growth and technical change among these models. Using a primal approach, we decompose TFP growth into different components. The models are then used to measure productivity and technical change in the Swedish cement industry. In general, the results are found to be model dependent and often conflicting, although much less so for returns to scale and overall productivity growth.
