Trends in the Transitory Variance of Earnings in the United States
分解了1969至1996年美国男性年收入横截面方差的上升，发现永久性方差自1970年代末持续上升，暂时性方差在1980年代上升但1990年代下降。
We decompose the rise in cross-sectional variance of male annual earnings in the United States from 1969 to 1996 into permanent and transitory components. We find that the variance of permanent earnings began rising in the the late 1970s and has continued to rise in the 1980s. The variance of transitory earnings also rose in the 1980s but declined in the 1990s. There are lags in the earnings process which require a structural model to pinpoint the exact calendar times at which the changes in trends occurred. Copyright Royal Economic Society 2002.
