We find remote work improves individual productivity but worsens worker
selection. Calls per hour rose sharply by 7% when individuals switched to remote
work in 2018 and 2019. Similarly, when the entire on-site workforce went remote
after Covid-19, the productivity of formerly on-site workers rose by 8-10%
relative to their already remote peers. Nevertheless, remote workers answered
10% fewer calls per hour than on-site workers before the pandemic and
consequently earned 6% lower wages.
