Identification Properties of Recent Production Function Estimators
考察了Olley-Pakes和Levinsohn-Petrin两种生产函数估计方法,指出它们存在函数依赖问题,并提出一种基于相同思想但更稳健的替代方法。
This paper examines some of the recent literature on the estimation of production functions.We focus on techniques suggested in two recent papers, Olley andPakes (1996), andLevinsohn andPetrin (2003).While there are some solid and intuitive identification ideas in these papers, we argue that the techniques can suffer from functional dependence problems.We suggest an alternative approach that is based on the ideas in these papers, but does not suffer from the functional dependence problems and produces consistent estimates under alternative data generating processes for which the original procedures do not.
