Is Job Stability in the United States Falling? Reconciling Trends in the Current Population Survey and Panel Study of Income Dynamics
比较了当前人口调查和收入动态面板研究这两套数据中雇主任职年限的趋势，发现使用可比样本和定义后，两者在1980-1990年代并无显著差异，且均未显示短期任职比例有明显变化。
This article considers whether two commonly used sources of information on employer tenure, the Panel Study of Income Dynamics and the Current Population Survey, yield systematically different trends in employer tenure. Little evidence of a discrepancy between the data sets in the 1980s or 1990s is found when comparable samples, variable definitions, and time frames are used. Neither data set shows a significant trend in the share of workers with 1 year or less of tenure, while both data sets show an increase in the fraction of men with less than 10 years of tenure starting in the late 1980s.
