RISING OCCUPATIONAL AND INDUSTRY MOBILITY IN THE UNITED STATES: 1968–97*
利用PSID数据，分析了1968-97年间美国工人职业和行业流动性的高水平及显著增长，并开发了控制编码测量误差的方法，对理解工资不平等、生产率等议题有重要意义。
We document and analyze the high level and the substantial increase in worker mobility in the United States over the 1968–97 period at various levels of occupational and industry aggregation. This is important in light of the recent findings that human capital of workers is largely occupation‐ or industry‐specific. To control for measurement error in occupation and industry coding, we develop a method that utilizes the PSID Retrospective Occupation‐Industry Supplemental Data Files. We emphasize the importance of our findings for understanding a number of issues such as the changes in wage inequality, aggregate productivity, job stability, and life‐cycle earnings profiles.
