Job matching across occupational labour markets
质疑了职位匹配仅发生在单一职业劳动力市场的传统假设，通过构建职业拓扑并采用考虑截面依赖的实证模型，验证了跨职业劳动力市场的职位搜索与匹配现象，为估计匹配弹性提供了改进模型。
The article refers to job matching processes in occupational labour markets in terms of jobs that share extensive commonalities in their required qualifications and tasks. To date, all studies in this field have been based on the assumption that matching processes only transpire within distinct occupational labour markets and that no occupational changes occur. I present theoretical and empirical arguments that undermine the validity of this assumption. I construct an ‘occupational topology’ based on information about the ways occupational groups may be seen as alternatives in searches for jobs or workers. I then use different empirical models that consider cross-sectional dependency to test the hypothesis that job search and matching occur across occupational labour markets. The results support my hypothesis. The findings suggest that an augmented empirical model should be used that considers job and worker searches across occupational labour markets in estimating job matching elasticities.
