Replication data for: New Evidence on Earnings Volatility in Survey and Administrative Data

Despite the rise in cross-sectional inequality since the late 1990s, there is little consensus on trends in earnings volatility during this period. Using consistent samples and methods in administrative earnings data matched to the Survey of Income and Program Participation (SIPP GSF) and survey data from the Panel Study of Income Dynamics (PSID), we examine earnings volatility for men from 1978 through 2011. In contrast to the apparent inconsistency in trends across administrative and survey data in the existing literature, we find recent increases in volatility in the SIPP GSF and the PSID, though increases are larger in the PSID.

尽管自20世纪90年代末以来，横截面不平等（cross-sectional inequality）程度有所上升，但学界对同期收入波动性（earnings volatility）的变化趋势尚未达成统一共识。本研究采用匹配收入与项目参与调查（Survey of Income and Program Participation，SIPP GSF）的行政收入数据，以及收入动态追踪调查（Panel Study of Income Dynamics，PSID）的调研数据，通过统一的样本与分析方法，考察了1978年至2011年间男性群体的收入波动性变化。与现有文献中行政数据与调研数据所得趋势存在明显矛盾的结论不同，本研究发现SIPP GSF与PSID数据均显示近年来收入波动性有所上升，且PSID数据中的增幅更大。
