February 22, 2023, Paper: "The pandemic catalyzed an enduring shift to hybrid and fully-remote work arrangements. To study this shift, we examine 250 million vacancy postings in five Englishspeaking countries. Our measurements rely on a state-of-the-art language-processing framework that we fit, test, and refine using 30,000 human classifications. We achieve 99% accuracy in flagging job postings that advertise hybrid or fully remote work, greatly outperforming dictionary-based methods and also outperforming other machinelearning methods. From 2019 to 2022, the share of postings that say new employees can work remotely one or more days per week rose three-fold in the U.S and by a factor of five or more in Australia, Canada, New Zealand and the U.K. These developments are highly non-uniform across and within cities, industries, occupations, and companies. Even when zooming in on employers in the same industry that compete for talent in the same occupations, we find huge differences in the share of postings that say the job allows remote work."
