New work goes to younger, more educated workers and pays persistent wage premiums that shrink as the expertise behind it spreads. https://aifaultline.com/research/p/doi-10-1093-qje-qjae008/https://aifaultline.com/research/p/doi-10-1093-qje-qjae008/Fri, 15 Mar 2024 00:00:00 +0000Using eight decades of new job titles linked to Census microdata and patent-based measures, the authors find that most current US employment is in job specialties introduced since 1940. New work arises from innovations that complement occupations' outputs and from demand shocks, while its creation has shifted toward high-paid professional and low-paid service jobs since 1980.
