Estimation of Technical Efficiency Using Flexible Functional Form and Panel Data
提出一个计量模型，允许非径向的投入特定技术无效率度量，并给出减少对无效率分布假设依赖的估计方法，利用芬兰12家铸造厂的面板数据估计劳动和能源的技术效率。
This article presents an econometric model capable of accommodating a nonradial measure of input-specific technical inefficiency and suggests an estimation technique that reduces dependency on distributional assumptions on inefficiency. It also makes use of the demand system derived from a flexible cost function and imposes concavity restrictions as required by economic theory. Panel data on 12 Finnish foundry plants are used to estimate technical efficiency of labor and energy for each of these plants.
