Doctoral Dissertation Research: Competition and Niches in Occupational Labor Markets: An Ecological Theory of Occupational Labor Supply

这一博士论文研究项目将探索社会结构对职业劳动力供应的影响。目前劳动经济学领域的研究很少明确关注社会网络对职业劳动力供给的影响。基于第一个PI关于社会群体为成员竞争的生态理论的先前工作，本理论认为群体居住在社会人口相空间的有限区域，竞争是由在这个空间中重叠的多个群体创造的。一个群体在社会人口空间中的位置是由其成员的社会人口特征决定的。该项目将探索这一理论对职业劳动力供应的影响。它将使用当前人口调查年度人口档案(1988-1998)中的数据，对美国的职业系统进行建模。

This doctoral dissertation research project will explore social structural influences on the supply of labor to occupations. Current research in the field of labor economics pays little explicit attention to the effect of social networks on the supply of labor to occupations. Building upon the first PI's prior work on the ecological theory of competition of social groups for members, the present theory argues that groups inhabit bounded regions of a sociodemographic phase space, and that competition is created by multiple groups overlapping in this space. A group's position in sociodemographic space is determined by the aggregate sociodemographic characteristics of its members. The project will explore the implications of this theory with respect to the supply of labor to occupations. It will model a system of occupations in the U.S., using data taken from the Current Population Survey Annual Demographic Files (1988-1998).
