> remote work (also called telework) is likely to become far more common in the future for four reasons. First, the productivity of individual workers who switch to remote work is comparable or higher than their colocated peers, at least in some industries. Second, matching firms to geographically distant workers is becoming easier thanks to technological and social developments. Third, remote workers tend to be cheaper because workers value geographic flexibility and the ability to work remotely. Fourth, the benefits of knowledge spillovers from being physically close to other knowledge workers has been falling and may no longer exist in many domains of knowledge. While the prevalence of remote work (pre-covid-19) is small, I show it was already rising rapidly with plenty of room to continue growing. Finally, I argue remote work has positive externalities and should be promoted by policy-makers.
