Determinants Of Work Location Choice In Academia, Alessandra Migliore, Chiara Tagliaro, Ying Hua

CIB Conferences

The COVID-19 pandemic has forced most workers to work from home (WFH). At first glance, this seems not to be a significant change for academics, who, even in regular times, are used to performing their research activities autonomously and balancing on-campus and off-campus locations. Instead, precisely because of their flexible habits, it is interesting to study where academics worked during the COVID-19 pandemic and which factors relate to their location choices. This paper addresses these issues using survey data from 7,865 Italian-tenured academics. First, cluster analysis unveils four main location choices of Italian academics during the COVID-19 pandemic depending on …
