This working paper, published by the National Bureau of Economic Research, investigates how mobile app usage among college students, particularly the use of gaming and social apps, affects academic performance and labor market outcomes. The study uses data from a Chinese university combined with mobile phone records and highlights the role of peer influence in exacerbating these effects. The researchers examine both direct effects of app usage and indirect effects due to roommates’ behaviors, demonstrating that mobile app usage is contagious among peers and leads to significant negative impacts on academic performance and future wages. The report suggests that increased app usage lowers GPAs and wages, while also reducing physical health and time spent on academic activities like studying. Extending China’s restrictions on gaming for minors to college students could help mitigate some of these effects, improving labor market outcomes.
The study provides policy implications, suggesting that restricting gaming time could increase post-graduation wages. The paper also delves into time allocation behaviors and how excessive app usage contributes to academic decline and labor market challenges.
