q2 i? Workers with more specialised skill portfolios are more likely to sort into higher-wage occupations, while specialisation is only weakly related to adaptive outcomes such as skill acquisition and mobility. → Carpanelli 2026

q2 · i? · associational · r2

Regression analysis of a longitudinal LinkedIn panel of approximately 2.4 million US workers, with explanatory variables measured 2020–2022 and outcomes 2023–2025. The study reports that "Specialisation is strongly associated with sorting into higher wage occupations" while adaptive outcomes relate only weakly to it. No effect sizes are printed.

"Specialisation is strongly associated with sorting into higher wage occupations but only weakly related to adaptive outcomes, confirming that productive depth alone is insufficient for resilience."

Discussion¶

Related Claims¶

• Skill portfolio diversity is positively associated with skill acquisition, occupational mobility, and transitions into lower-AI-exposure occupations — related
• Mean skill diversity rises from low to moderate specialisation before declining among the most specialised workers — related
• Workers closest to the diversity frontier show the strongest adaptive outcomes, while frontier position is not associated with stronger wage sorting — related
• Skill portfolio measures stratify by demographics: men, younger cohorts, and more educated workers show higher specialisation — related
