Parametric Estimation of Technical and Allocative Inefficiency with Panel Data
提出一种面板数据参数方法，可灵活估计企业层面的技术无效率和投入配置无效率，并以美国航空公司数据验证。
The error-components approach to estimating allocative inefficiency imposes restrictive assumptions on the distributions of the errors and functional form. The parametric approach does not require special assumptions about the error distribution or technology but typically assumes technical efficiency or restrictive functional forms. The parametric approach also allows for systematic firm responses to shadow prices. The authors generalize the parametric approach to a panel data setting and show that input and firm-specific allocative inefficiency, as well as firm-specific technical inefficiency, can be identified and estimated using a flexible functional form. This is demonstrated empirically with an application to U.S. airlines.
