Occupational and Job Mobility in the US*
利用月度CPS数据的有限纵向维度，提出测量美国工人职业与工作流动性的新方法，发现1979-2006年间约3.5%的男性工人连续两月报告不同职业，且该比率呈顺周期变化。
Abstract We propose a new methodology to measure worker mobility across occupations and jobs in the US, building on the limited longitudinal dimension of monthly CPS data. For the period 1979–2006, we find that about 3.5% of male workers employed in two consecutive months report different three‐digit occupations. This rate is procyclical, mildly rising in the 1980s and falling after 1995. We also revise upward current estimates of aggregate job‐to‐job mobility since 1994, from 2.7% to 3.2% of employment per month. Despite extreme similarity of average levels and time‐series behavior, occupational and job mobility are only weakly correlated.
