Measuring Job-Finding Rates and Matching Efficiency with Heterogeneous Job-Seekers
开发了一个框架，用于在求职者群体异质的情况下测量匹配效率，发现2001至2013年间整体匹配效率平稳下降，而忽视异质性会高估2007至2009年间的效率下降幅度。
Matching efficiency is the productivity of the process for matching job-seekers to available jobs. Job-finding is the output; vacant jobs and active job-seekers are the inputs.We develop a framework for measuring matching productivity when the population of job-seekers is heterogeneous. We find that overall matching efficiency declined smoothly over the period from 2001 through 2013. Measures of matching efficiency that neglect heterogeneity among the unemployed and also neglect job-seekers other than the unemployed suggest a large 28 percent decline in efficiency between 2007 and 2009. Most of this apparent decline results from changes in the composition of job-seekers.
