我们将1969年至1996年美国男性年收入的横截面方差上升分解为永久性和暂时性两个部分。我们发现，永久收益的方差在20世纪70年代末开始上升，并在20世纪80年代继续上升。暂时性收益的方差在20世纪80年代也有所上升，但在90年代有所下降。在盈利过程中存在滞后，这需要一个结构模型来准确地确定趋势发生变化的确切日历时间。
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.
