Estimates of Year-to-Year Volatility in Earnings and in Household Incomes from Administrative, Survey, and Matched Data
利用行政收入记录、SIPP调查数据及其匹配数据，研究了1985至2005年间美国工人收入和家庭收入的逐年波动趋势，发现行政数据中波动性自1980年代中期以来大致稳定甚至略有下降，与调查数据及以往研究结论不同。
We document trends in the volatility in earnings and household incomes between 1985 and 2005 in three different data sources: administrative earnings records, the Survey of Income and Program Participation (SIPP) matched to administrative earnings records, and SIPP survey data. In all data sources, we find a substantial amount of year-to-year volatility in workers' earnings and household incomes. In the data sources that contain administrative earnings, we find that volatility has been roughly constant, and has even declined slightly, since the mid-1980s. These findings differ from what is found using survey data and what has been reported in previous studies.
