Nonconvexities, Heterogeneity and the Aggregate #Lab Market

这个项目继续了一般均衡宏观经济学领域的一系列研究。研究人员已经为宏观经济学-劳动力领域的各种难题提供了一些有趣的解决方案，并开发了极大地提高代表性代理人模型的有用性的技术。这项持续的研究有两个主要目标。第一个是扩展非凸性劳动力市场模型的分析，第二个是研究明确允许异质性的劳动力市场模型。关于第一个目标，扩展包括比较不同类型的非凸性，最优资源分配的权力下放，特别注意非自愿失业，纳入劳动力市场流动，以及仔细分析非凸性所隐含的动态关系。关于第二个目标，重点将是将异质性引入劳动力市场的总体模型。所考虑的异质性形式包括熟练和非熟练劳动力、已婚男性和已婚女性、以及成年人和年轻人。目的是研究模型，这些模型将解释这些群体经历的周期性就业波动的巨大差异。分析的重点将是不同规格的技术和偏好在多大程度上可以产生所观察到的现象。

This project continues a line of research in the area of general equilibrium macroeconomics. The investigator has already offered a number of interesting solutions to various puzzles in the macroeconomics-labor area, and has developed techniques that greatly enhance the usefulness of representative agent models. This continued research has two main goals. The first is to extend the analysis of the labor market models with nonconvexities, and the second is to study models of the labor market which explicitly allow for heterogeneity . With regard to the first goal, the extensions include a comparison of different types of nonconvexities, decentralization of optimal resource allocations with particular attention paid to involuntary unemployment, incorporation of labor market flows, and a careful analysis of the dynamics relationships implied by nonconvexities. With respect to the second goal, the emphasis will be on introducing heterogeneity into aggregate models of the labor market. The forms of heterogeneity considered are skilled and unskilled labor, married males and married females, and adults and youths. The aim is to study models which will account for the large differences in cyclical employment fluctuations experienced by these groups. The analysis will focus on to what extent different specifications of technology and preferences can produce the observed phenomena.
