TY - RPRT AU - Guerrico, Sofía Fernández AU - Tojerow, Ilan TI - The Effect of Broadband Internet on Mental Health-Related Disability Insurance Claims PY - 2025/Sep/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 18130 UR - https://www.iza.org/index.php/publications/dp18130 AB - We examine the causal impact of high-speed internet on adult mental health using administrative data from Belgium. We exploit predetermined telecommunications infrastructure and broadband technology's distance-sensitive nature for identification. Our difference-in-differences estimates show internet increased mental health-related disability insurance claims by 0.054 percentage points—a 31% increase relative to the control group. These findings are supported by increased antidepressant use at the municipality level. Results point to a work-related mechanism: effects are concentrated among knowledge workers and those in high work-from-home potential jobs. Time-use data show a substitution from leisure to work and less social interaction on weekends. KW - disability insurance KW - internet KW - mental health KW - employment ER -
