The quality of the estimators of the ETI
通过蒙特卡洛模拟评估了税收政策设计中关键参数：应税收入弹性的两种主流估计方法（工具变量回归和聚束估计）的偏差和精度，并提出了间接推断估计来改进测量质量。
The elasticity of taxable income (ETI) is a central statistic for tax policy design. One purpose of the present paper is to use Monte Carlo simulation techniques to assess the bias and precision of the prevalent estimators in the literature, the IV-regression estimator and the bunching estimator. Thereby, we aim to provide arguments in favor of, or against, using these methods. Another is to suggest indirect inference estimation to improve the quality of the measurement of the ETI. While IV-regression estimators perform well in terms of bias under certain conditions, they are more variable than bunching estimators. We also find that bunching estimators can be biased downward. The estimators based on indirect inference principles are practically unbiased and more precise than the other estimators.
