The International Monetary Fund published a Staff Discussion Note assessing how “new skills”, especially IT and AI-related skills, are reshaping labor markets, wages, and hiring, and proposing new cross-country metrics to gauge skill gaps. Using vacancy and worker-profile data alongside labor market and education statistics, the note finds that rising demand for new skills can lift wages and employment overall but may deepen job polarization, while AI-related skill diffusion is linked to weaker employment outcomes in some AI-exposed occupations. Across advanced economies, roughly 1 in 10 job postings requires at least one new skill, about twice the incidence in emerging market economies, with new skills often appearing first in the United States and diffusing rapidly elsewhere. Vacancies listing new skills are associated with higher wage offers, around 3 to 3.4 percent in the United States and the United Kingdom, and in US commuting zones a 1 percentage point rise in the share of postings requiring new skills is associated with 2.3 percent higher average wages and 1.3 percent higher employment. By contrast, focusing on AI-related new skills, the note reports higher wages for AI-skill vacancies but no gains in overall US employment, and lower employment in occupations with high exposure and low complementarity to AI, with employment levels 3.6 percent lower in regions with greater AI-skill demand five years after these skills appear. The analysis also links new-skill demand to young, innovative, less financially constrained firms and highlights talent-driven mergers and acquisitions as a channel for securing scarce expertise, with potential implications for concentration and skill diffusion. As a policy framework, the note introduces a Skill Imbalance Index and a Skill Readiness Index to compare countries’ relative demand for and capacity to supply new skills. It suggests that economies where demand outpaces supply should prioritize education and reskilling, including broader IT training and stronger STEM education, while economies with relatively stronger supply should focus on strengthening firms’ ability to absorb skills through innovation and access to finance, with the note published to elicit comments and encourage debate and not representing the views of the IMF or its Executive Board.
