Estimation of firm-specific technological bias, technical change and total factor productivity growth: a dual approach
使用多种对偶参数计量模型，估计企业特定技术变革和投入产出偏向，并比较不同模型下全要素生产率增长的稳健性，以日本化工行业面板数据为例。
This paper deals with modeling firm-specific technical change (TC), and technological biases (inputs and scale) in estimating total factor productivity (TFP) growth. Several dual parametric econometric models are used for this purpose. We examine robustness of TFP growth and TC among competing models. These models include the traditional time trend (TT) model and the general index (GI) model. The TT and the GI models are generalized to accommodate firm-specific TC and technological bias (in inputs and output). Both nested and non-nested tests are used to select the appropriate models. Firm-level panel data from the Japanese chemical industry during 1968- 1987 is used as an application.
