介绍含单位异质系数的动态分布回归面板数据模型,用固定效应法估计系数及泛函,研究其对反事实变化的响应,解决推断稳健性问题,通过劳动收入实证展示方法实用性。

摘要:

我们引入了一个跨单位具有异质系数的动态分布回归面板数据模型。主要关注的对象是这些系数的泛函,包括结果变量的预测一步超前和静态横截面分布。系数及其泛函通过固定效应方法进行估计。我们研究这些泛函如何响应初始条件或协变量值的反事实变化而变化。我们还识别了一个与推断对未知系数异质程度的稳健性相关的一致性问题,并提出了一种横截面自举方法,用于对函数值对象进行一致有效的推断。我们通过对个人收入动态的实证应用展示了我们方法的实用性。利用年度收入动态面板研究数据,我们确定了存在大量系数异质性。然后,我们强调了一些我们的方法可以解决的重要实证问题。首先,我们量化了负劳动收入冲击对未来劳动收入分布的影响。其次,我们证明了收入流动性的异质性及其对个人陷入贫困发生率的影响。模拟证据证实了我们的程序在小样本中效果良好。

英文摘要:

We introduce a dynamic distribution regression panel data model with heterogeneous coefficients across units. The objects of primary interest are functionals of these coefficients, including predicted one-step-ahead and stationary cross-sectional distributions of the outcome variable. Coefficients and their functionals are estimated via fixed effect methods. We investigate how these functionals vary in response to counterfactual changes in initial conditions or covariate values. We also identify a uniformity problem related to the robustness of inference to the unknown degree of coefficient heterogeneity, and propose a cross-sectional bootstrap method for uniformly valid inference on function-valued objects. We showcase the utility of our approach through an empirical application to individual income dynamics. Employing the annual Panel Study of Income Dynamics data, we establish the presence of substantial coefficient heterogeneity. We then highlight some important empirical questions that our methodology can address. First, we quantify the impact of a negative labor income shock on the distribution of future labor income. Second, we demonstrate the existence of heterogeneity in income mobility, and its implications for an individuals' incidence to be trapped in poverty. Simulation evidence confirms that our procedures work well in small samples.
