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, 2025We 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.

Rebalancing in China: Progress and Prospects
Longmei Zhang, Aug 02, 2017This paper develops a framework for China’s rebalancing, reviews past progress, and discusses medium-term prospects. China has advanced well in reducing its excessive external surplus and moving towards consumption and services, while still lagging behind in reducing credit reliance, environmental pollution, and income inequality. Going forward, the economy will continue rebalancing in many dimensions, while credit will remain China’s Achilles heel unless decisive corporate restructuring and SOE reforms are implemented.

Ruixue Jia, Xiaohuan Lan, Gerard Padró i Miquel, May 19, 2021The children of cadres have a higher likelihood of owning business in China, and this relationship varies greatly with government intervention in the economy.
