人工智能对新近大学毕业生就业前景的影响引发了激烈争论,对于影响的幅度,乃至这些潜在影响发生的时间,均尚无共识。利用CPS微观数据,我们首次估计了人工智能对2026年6月、7月和8月新近大学毕业生失业的影响。我们提供的证据提示,夏季月份的失业率尤其高,而2026年可能是人工智能在工作场所的使用广泛到足以检测其对新近大学毕业生影响的第一年;这一群体被认为最容易被人工智能替代。我们采用不预设处理时点的方法,发现2026年夏季的失业率与往年夏季月份相比并未骤升,相对于年长的大学毕业生或没有大学学位的年轻劳动者,也未显著上升。我们还首次分析了一种扩展的失业定义,将报告“想要工作”的人也纳入其中。这一扩展使新近大学毕业生的失业率提高了近两个百分点,但即使纳入这些“被边缘化的失业者”,我们仍未发现2026年夏季失业率出现统计显著上升的证据。我们以年长的大学毕业生和没有大学学位的年轻劳动者作为对照组,估计了双重差分和事件研究交互模型,未发现相对失业率上升的证据。最后,我们估计了将2026年的失业情况与各职业的人工智能暴露度及远程工作可得性进行交互的模型,发现一些证据表明,失业情况与远程工作可得性存在正向关系。
Abstract
The impact of AI on the employment prospects of recent college graduates is hotly debated with no consensus on the magnitude of impacts nor even the timing of those potential impacts. Using CPS microdata, we provide the first estimates of the effects of AI on the unemployment of recent college graduates in June, July and August 2026. We provide evidence suggesting that unemployment rates are especially high for summer months and that 2026 might be the first year of widespread enough AI use in the workplace to detect impacts of AI on recent college graduates, the group argued to be most vulnerable to AI replacement. Taking an agnostic approach to defining treatment timing, we find that unemployment rates did not spike in summer 2026 relative to summer months in previous years and did not rise in a significant way relative to older college graduates or young workers without a college degree. We also provide the first analysis of an expanded definition of unemployment that includes those who report “wanting a job” which adds nearly two percentage points to the unemployment rate of recent college graduates but we find no evidence of a statistically significant increase in summer 2026 even after adding these “sidelined unemployed.” We estimate difference-in-differences and event-study interaction models using both older college graduates and young non-college graduates as comparison groups and do not find evidence of an increase in relative unemployment rates. Finally, we estimate models in which we interact 2026 unemployment with AI exposure and remote work availability by occupation and find some evidence of a positive relationship with remote work availability.
