摘要
本文基于 IV probit 估计器的扩展和控制函数的思想,提出了存在内生回归因子时半参数分布回归模型的 IV 估计器。我们讨论了估计器的因果解释,以及确保分布函数单调递增的两种方法(单调重排和同调回归)。我们还提供了渐近特性和模拟证据。通过将德国 SOEP 数据应用于收入方程,我们发现了与不一致的非基于 IV 的估计值在统计上的显著差异和异质性差异。
Semiparametric distribution regression with instruments and monotonicity
This paper proposes IV-based estimators for the semiparametric distribution regression model in the presence of an endogenous regressor, which are based on an extension of IV probit estimators and the idea of control functions. We discuss the causal interpretation of the estimators and two methods (monotone rearrangement and isotonic regression) to ensure a monotonically increasing distribution function. Asymptotic properties and simulation evidence are provided. An application to income equations with German SOEP data reveals statistically significant and heterogeneous differences to the inconsistent non-IV-based estimator.
期刊介绍:
Labour Economics is devoted to publishing research in the field of labour economics both on the microeconomic and on the macroeconomic level, in a balanced mix of theory, empirical testing and policy applications. It gives due recognition to analysis and explanation of institutional arrangements of national labour markets and the impact of these institutions on labour market outcomes.
