Estimation and testing of kink regression model
【摘要】
Kink regression model which assumes continuity at the threshold point has wide applications in statistics and economics. Existing estimation methods are obtained under a rather important assumption that the errors are mean independent of the threshold variable, namely, it is exogenous. However, endogeneity can arise as a result of omitted variables, lagged dependent threshold variable, measurement error and many other sources. In this paper, we consider the estimation and testing for the kink regression model with both endogenous threshold variable and regressors. We find that the 2SLS estimator of the threshold point is inconsistent. The continuity feature of the regression prompts us to try method based on the GMM principle using nonlinear instruments. We derive the asymptotic properties using a different way from the usual GMM estimators as the objective function is not smooth with respect to the threshold parameter. A sup-Wald test for the presence of kink effect is established and a bootstrap procedure to gain the p-values is introduced. Monte Carlo simulations show that the proposed estimator and testing procedure perform well. The proposed procedures is also illustrated with en empirical application.

讲座主题:
环境规制对中国就业“去工业化”的影响
【摘要】
环境“库兹涅茨曲线”假说认为,环境与人均收入之间呈倒“U”型关系,在经济发展的初始阶段,随着经济的增长,环境质量逐渐恶化,污染加剧,当达到一定的“拐点”时,环境质量将得到改善。这似乎暗示着收入效应可以有效减少环境污染。此外,结构变迁的“库兹涅茨曲线”认为,制造业份额与人均收入也存在着倒“U”型关系,随着人均收入的继续增加,制造业份额也将不断减少。这两条与人均收入均呈倒“U”型关系的库兹涅兹曲线似乎背后存在着统一的逻辑。随着2020年9月习近平总书记正式宣布,中国力争2030年前实现碳达峰,2060年前实现碳中和的“双碳”目标,“双碳”目标正式写入“十四五”规划中,碳中和、碳达峰协议的签订对中国制造业乃至三大产业将会深远影响,探讨环境“库兹涅兹”曲线和结构“库兹涅兹”曲线背后的统一逻辑将具有重要意义。本文初步讨论了环境规制对中国就业“去工业化”的影响。
