A Comparative Study of Instrumental Variables Estimators for Nonlinear Simultaneous Models
非线性联立模型工具变量估计量的比较研究
In the context of single equation approaches to the estimation of nonlinear simultaneous models, three classes of estimators can be established, using different fitted values established by a stage-one regression. The first uses the Fitted values of the nonlinear function in the second-stage regression. The second, called here the naive instrument, substitutes a fitted value inside the nonlinear function. The third uses an estimate of the conditional expectation of the…
