Mobile Internet and Mental Health

(with Lipeng Chen)

Abstract The past decade witnessed a significant worsening of mental health in the United States, which coincides with the expansion of mobile Internet and the following increase in screen time. In this project, we estimate the impact of mobile Internet on mental health using a two-way fixed effects model, taking advantage of the temporal and spatial variation of 3G Internet coverage. We find that people’s mental health became worse after the arrival of 3G Internet. This is driven by the increased use of social media. We also find that young, high-income, and highly educated people were more affected by mobile Internet in this mental health crisis.
