Matching in Labor Markets and Epidemics

这项研究包括两个项目。第一个将分析不平等和高技能工人被分离到不同公司的同时增加的情况。似乎工人已经从通用汽车这样的公司转移到了微软或麦当劳这样的公司，这些公司把不同技能的工人结合在一起，雇佣了类似技能的工人。将开发一个模型来探索这一现象。该模型的一个含义是，无论是基于技能的技术进步还是增加的技能分散度，都会导致高技能工人分离到不同的公司，并降低低技能工人的工资。该项目的第二部分将根据关于感染风险的信息的各种假设，在性伴匹配的基础上开发和测试艾滋病传播模型。此外，对行为如何影响艾滋病毒流行率的流行病学分析将与对艾滋病毒流行率如何影响个人行为动机的经济分析相结合。

This research encompasses two projects. The first will analyze the simultaneous increase in inequality and in the segregation of high skill workers into separate firms. It appears that workers have been moving from firms like General Motors, which combine workers of different skills, to firms like Microsoft or McDonalds which hire workers of similar skills. A model will be developed to explore this phenomenon. An implication of the model is that either skill-based technological progress or increased skill dispersion can cause high skill workers to segregate into separate firms and reduce wages of low skill workers. The second part of the project will develop and test a model of the spread of AIDS based on matching of sexual partners under various assumptions about the information concerning the risk of infection. In addition, an epidemiological analysis of how behavior affects HIV prevalence will be integrated with an economic analysis of how HIV prevalence affects incentives for individuals behavior.
