Dakyung Seong

AI总结:

本文针对多个弱工具变量下的内生二元响应模型,提出正则化条件最大似然估计量和正则化非线性最小二乘估计量,并通过模拟及家庭收入对大学完成影响的实证验证其优越性。

摘要:

本文研究了一个具有多个弱工具变量的内生二元响应模型。我们采用控制函数方法和正则化方案,以在存在多个弱工具变量的情况下获得内生二元响应模型更好的估计结果。本文提供了两个一致且渐近正态分布的估计量,分别称为正则化条件最大似然估计量(RCMLE)和正则化非线性最小二乘估计量(RNLSE)。蒙特卡洛模拟表明,当存在多个弱工具变量时,所提出的估计量优于现有估计量。我们使用所提出的估计方法来考察家庭收入对大学完成情况的影响。

英文摘要:

This paper considers an endogenous binary response model with many weak instruments. We employ a control function approach and a regularization scheme to obtain better estimation results for the endogenous binary response model in the presence of many weak instruments. Two consistent and asymptotically normally distributed estimators are provided, each of which is called a regularized conditional maximum likelihood estimator (RCMLE) and a regularized nonlinear least squares estimator (RNLSE). Monte Carlo simulations show that the proposed estimators outperform the existing ones when there are many weak instruments. We use the proposed estimation method to examine the effect of family income on college completion.
