🤖 AI Summary
This study systematically assesses occupational exposure to and substitution risk from artificial intelligence—particularly large language models (LLMs)—at the task level.
Method: We propose a novel, task-level dual-index framework—Task Exposure to AI (TEAI) and Task Replacement by AI (TRAI)—grounded in open-source LLMs (e.g., Llama, Phi), the O*NET task database, expert human annotations, and statistical modeling, yielding a reproducible, quantifiable assessment framework.
Contribution/Results: We find TEAI positively correlates with cognitive ability but negatively with social skill requirements; approximately one-third of U.S. occupations exhibit high exposure, concentrated among high-education roles. Counterintuitively, TEAI is significantly positively associated with employment and wage growth from 2003–2023, suggesting a net long-term labor-market–enhancing effect of AI. TRAI reveals substantial intra-occupational heterogeneity in substitutability, underscoring the prevalence of human–AI complementarity rather than wholesale replacement.
📝 Abstract
AI and related technologies are reshaping jobs and tasks, either by automating or augmenting human skills in the workplace. Many researchers have been working on estimating if and to what extent jobs and tasks are exposed to the risk of being automatized by AI-related technologies. Our work tackles this issue through a data-driven approach by: (i) developing a reproducible framework that uses cutting-edge open-source large language models to assess the current capabilities of AI and robotics in performing job-related tasks; (ii) formalizing and computing a measure of AI exposure by occupation, the Task Exposure to AI (TEAI) index, and a measure of Task Replacement by AI (TRAI), both validated through a human user evaluation and compared with the state of the art. Our results show that the TEAI index is positively correlated with cognitive, problem-solving and management skills, while it is negatively correlated with social skills. Applying the index to the US, we obtain that about one-third of US employment is highly exposed to AI, primarily in high-skill jobs requiring a graduate or postgraduate level of education. We also find that AI exposure is positively associated with both employment and wage growth in 2003-2023, suggesting that AI has an overall positive effect on productivity. Considering specifically the TRAI index, we find that even in high-skill occupations, AI exhibits high variability in task substitution, suggesting that AI and humans complement each other within the same occupation, while the allocation of tasks within occupations is likely to change.
