Evidence on Adverse Selection and Establishment Size in the Labor Market
研究发现，被解雇工人比因工厂关闭失业的工人工资损失更大，原因并非前者能力更低，而是他们原本在规模更大、工资更高的机构工作。控制机构规模后，两组工人的工资损失差异几乎消失。
A commonly suggested explanation for the finding that laid-off workers have greater mean post-displacement earnings losses than workers who lose their jobs through plant closings is that the former are of lower quality than the latter. But there is also an alternative explanation for this result: laid-off workers suffer larger earnings losses because, as a group, they have more to lose in the first place, having been displaced from larger, higher-wage establishments. An analysis of data from the National Longitudinal Survey of Youth confirms this hypothesis. Accounting for establishment size removes virtually all of the difference in wage losses for the two groups of displaced workers.
