Dynamic Input Decisions in Econometric Production Models
开发了一种计量方法，用于估计包含连续中间投入决策的动态生产模型，解决了投入内生性和变量相关导致的识别困难，并以小麦灌溉为例说明方法。
Abstract This study develops an econometric methodology for estimating dynamic production models with sequential intermediate input decisions. Two problems arise in the study of intermediate inputs: intermediate input decisions may be endogenous to final output, and intermediate inputs are likely to be correlated with each other and other variables, making identification and estimation difficult. The econometric model measures the productivity of intermediate inputs, taking into account the farmer's sequential input decisions and input productivity differences during the growing season. A multistage Cobb‐Douglas model of wheat response to irrigation water is used to illustrate the proposed methods.
