Do Recessions Accelerate Routine-Biased Technological Change? Evidence from Vacancy Postings
研究发现，受大衰退冲击严重的都市统计区，职位空缺中的技能要求相对提高更多，且持续至2015年底，与资本投资增加相关，尤其在常规认知型职业中，表明衰退加速了生产向常规偏向型技术和高技能工人的重组。
We show that skill requirements in job vacancy postings differentially increased in MSAs that were hit hard by the Great Recession, relative to less hard-hit areas. These increases persist through at least the end of 2015 and are correlated with increases in capital investments, both at the MSA and firm levels. We also find that effects are most pronounced in routine-cognitive occupations, which exhibit relative wage growth as well. We argue that this evidence is consistent with the restructuring of production toward routine-biased technologies and the more-skilled workers that complement them, and that the Great Recession accelerated this process.
