Using data from the China Health and Retirement Longitudinal Study (CHARLS) we estimated the effect of childhood vaccination on later-life schooling and cognitive abilities of elderly Chinese. We found that being vaccinated in childhood increases schooling by one year and improves numeracy and episodic memory scores by 6 percent on average.

Digital Distractions with Peer Influence: The Impact of Mobile App Usage on Academic and Labor Market Outcomes

Panle Jia Barwick, Siyu Chen, Chao Fu, Teng Li, Jan 08, 2025

We present the first comprehensive evidence of how app usage affects academic performance and early career outcomes. App usage is contagious: a one standard deviation (around 3.5 hours per day) increase in roommates’ app usage raises an individual’s own app usage by 5.8%, with substantial heterogeneity across students. A one standard deviation increase in app usage reduces GPAs by 36.2% of a within-cohort-major standard deviation and lowers wages by 2.3%. The effect of roommates’ app usage is over half the size of an individual’s own usage effect. High-frequency GPS data reveal that high app usage crowds out time in study halls and increases late arrivals at and absences from lectures.
