Recruiting Intensity during and after the Great Recession: National and Industry Evidence
利用2001年1月至2011年9月的职位空缺与劳动力流动调查数据，测量了全国和行业层面的职位填补率及每个空缺的招聘强度，发现行业层面的变动与标准匹配函数不符，但支持包含招聘强度的广义函数，其中建筑业在就业中占比不到5%，却贡献了大衰退期间职位填补率大幅波动的40%以上。
We measure job-filling rates and recruiting intensity per vacancy at the national and industry levels from January 2001 to September 2011 using data from the Job Openings and Labor Turnover Survey. Industry-level movements in these variables are at odds with implications of the standard matching function in labor search theory but consistent with a generalized function that incorporates an important role for recruiting intensity. Construction makes up less than five percent of employment but accounts for more than 40 percent of the large swings in the job-filling rate during and after the Great Recession.
