SIMULTANEOUS EQUATIONS WITH INCOMPLETE PANELS
通过蒙特卡洛模拟比较了非平衡面板数据下两方程联立模型的多种估计方法，发现基于简单方差成分估计的可行2SLS和3SLS方法表现良好，推荐实际应用。
This paper compares the performance of several single and system estimators of a two equation simultaneous model with unbalanced panel data. The Monte Carlo design varies the degree of unbalancedness in the data and the variance components ratio due to the individual effects. One useful result for applied researchers is that the feasible error components 2SLS and 3SLS procedures based on simple ANOVA type estimators of the variance components perform well with incomplete panels and are recommended in practice.
