The Great Recession has strongly influenced employment patterns across skill and gender groups in EU countries. We analyse how these changes in workforce composition might distort comparisons of conventional measures of gender wage gaps via non-random selection of workers into EU labour markets. We document that male selection (traditionally disregarded) has become positive during the recession, particularly in Southern Europe. As for female selection (traditionally positive), our findings are twofold. Following an increase in the labour-force participation of less-skilled women, due to an added-worker effect, these biases declined in some countries where new female entrants were able to find jobs, whereas they went up in other countries which suffered large female employment losses. Finally, we document that most of these changes in selection patterns were reversed during the subsequent recovery phase, confirming their cyclical nature.

大衰退期间性别选择的性质转变为就业

大衰退严重影响了欧盟国家技能和性别群体的就业模式。我们分析了劳动力构成的这些变化如何通过非随机选择进入欧盟劳动力市场的工人来扭曲对性别工资差距的传统衡量标准的比较。我们记录了在经济衰退期间男性选择（传统上被忽视）变得积极，特别是在南欧。至于女性选择（传统上是积极的），我们的发现是双重的。由于增加工人的影响，低技能妇女的劳动力参与率增加，这些偏见在一些新女性进入者能够找到工作的国家中有所下降，而在其他遭受大量女性就业损失的国家中则有所上升。最后，我们记录了选择模式的大部分变化在随后的恢复阶段被逆转，证实了它们的周期性。
