Estimation of Unemployment Duration from Grouped Data: A Comparative Study
比较了非参数和参数方法，利用澳大利亚社会保障部关于失业救济金领取者的分组数据来估计失业持续时间的平均长度，对评估劳动力市场状况有参考价值。
Economists have often found it useful to look at the average length of an unemployment spell in evaluating labor market conditions and in considering the labor market experience of the unemployed. Usually this statistic has to be estimated from grouped observations on interrupted (incomplete) unemployment spells. This paper is a comparative study of some nonparametric and parametric methods of estimating this quantity using Australian Department of Social Security data on unemployment benefit recipients.
