LLM兴起后，高暴露职业薪资上升，失业率未变。
The (Short-Term) Effects of Large Language Models on Unemployment and Earnings
- 用合成双重差分法分析不同职业对LLM的暴露程度

自2022年底ChatGPT发布以来，大型语言模型迅速普及，伴随而来的是生产率大幅提升的宣称以及对岗位替代的担忧。本文通过比较不同职业对这些技术暴露程度的差异，考察了大语言模型采用对劳动力市场的短期影响。采用合成双重差分法估计了LLM暴露对收入和失业率的影响。研究发现，高暴露职业的劳动者在ChatGPT推出后收入上升，而失业率保持稳定。结果表明，大语言模型带来的初期劳动力市场调整主要体现为收入变化，而非人员重新配置。
原文摘要 · Abstract (English)
Large Language Models have spread rapidly since the release of ChatGPT in late 2022, accompanied by claims of major productivity gains but also concerns about job displacement. This paper examines the short-run labor market effects of LLM adoption by comparing earnings and unemployment across occupations with differing levels of exposure to these technologies. Using a Synthetic Difference in Differences approach, we estimate the impact of LLM exposure on earnings and unemployment. Our findings show that workers in highly exposed occupations experienced earnings increases following ChatGPT's introduction, while unemployment rates remained unchanged. These results suggest that initial labor market adjustments to LLMs operate primarily through earnings rather than worker reallocation.
