Measuring the Total Number of US Job Seekers
研究发现自1980年以来美国被归类为不在劳动力队伍的求职者比例大幅上升，提出调整后的失业率指标，该指标使失业率上升5.2个百分点、消除下降趋势并降低波动性50%，且基于调整后失业率的菲利普斯曲线估计显示2008年后产出与通胀关系并未扁平化。
Abstract I document a substantial rise in the proportion of job seekers who are classified as out of the labour force in the United States since 1980. I propose an adjusted unemployment rate to account for these searchers; the adjustment increases the unemployment rate by 5.2 percentage points, rids the unemployment rate of its downward trend and decreases volatility by 50%. I also construct a measure of total search effort in the economy, including employed job seekers. Finally, estimates of the Phillips curve using the adjusted unemployment rate or total searcher rate show no sign of a flattening output-inflation relationship in the post-2008 recession period.
