Reconciling Occupational Mobility in the Current Population Survey
研究了1981-2018年美国职业流动性的测量问题,发现回顾性和纵向方法结果差异大,实际流动性比回顾性测量高60%-70%,且纵向测量误差随时间恶化。
Measuring occupational mobility from the Current Population Survey using retrospective or longitudinal methods generates substantially different outcomes, in both levels and trends. Using a generalized method of moments technique, we estimate the level of occupational mobility and the measurement error in both of these measures for 1981–2018. We estimate that occupational mobility has been trending down, particularly since 2000, consistent with retrospective measures of occupational mobility. However, estimated mobility is 2–3 percentage points or 60%–70% higher than retrospective measures. Measurement error in longitudinal measures is large and has been worsening over time.
