Misclassification Errors and the Underestimation of the US Unemployment Rate
利用测量误差文献的最新成果，发现美国当前人口调查中的劳动状态误分类导致官方失业率被严重低估，1996年至2011年间修正后的月失业率平均高出2.1个百分点。
Using recent results in the measurement error literature, we show that the official US unemployment rate substantially underestimates the true level of unemployment, due to misclassification errors in the labor force status in the Current Population Survey. During the period from January 1996 to August 2011, the corrected monthly unemployment rates are between 1 and 4.4 percentage points (2.1 percentage points on average) higher than the official rates, and are more sensitive to changes in business cycles. The labor force participation rates, however, are not affected by this correction.
