The finite sample performance of instrumental variable-based estimators of the Local Average Treatment Effect when controlling for covariates
控制协变量时工具变量局部平均处理效应估计量的有限样本表现
This paper investigates the finite sample performance of a range of parametric, semi-parametric, and non-parametric instrumental variable estimators when controlling for a fixed set of covariates to evaluate the local average treatment effect. Our simulation designs are based on empirical labor market data from the US and vary in several dimensions, including effect heterogeneity, instrument selectivity, instrument strength, outcome distribution, and sample size. Among the…
