Income Dynamics, Income Risk, and Inequality

工业化国家的收入差距很大，而且仍在扩大。重要的问题是，观察到的收入不平等有多少是由收入风险而不是个人决定造成的，生产率风险如何转化为收入风险，以及劳动力市场政策如何塑造收入动态，收入风险和不平等。目前的研究项目旨在回答这些问题，并从实际就业历史的数据估计收入风险。为了这个目的，我看的数据通过透镜的最先进的劳动力市场模型的重要特征所观察到的雇佣关系，即，长期合同和有限的合同可撤销性增强。对该模型的定量研究为劳动力市场风险的福利成本和最优劳动力市场政策的设计提供了新的见解。该框架-正在被微型化-也将被用来研究和讨论劳动力市场政策和收入风险之间的联系。该研究项目的目标是加深我们对收入动态，收入风险和不平等的相互作用的理解。

Observed income inequality in industrialized countries is large and is still growing. Important questions are how much of observed income inequality results from income risk in contrast to individual decisions, how does productivity risk translate into income risk, and finally how labor market policy shapes income dynamics, income risk, and inequality. The current research project aims at answering these question and estimates income risk from data of actual employment histories. For this purpose, I look at the data through the lens of a state of the art labor market model augmented by important features of observed employment relationships, namely, long-term contracts and limited contract enforceability. A quantitative investigation of this model delivers new insights for the welfare costs of labor market risk and the design of optimal labor market policy. The framework --- being mircofounded --- will also be used to study and discuss the link between labor market policy and income risk. The goal of this research project is to deepen our understanding of the interaction of income dynamics, income risk, and inequality.
