The Effect of Computer-Assisted Learning on Students’ Long-Term Development
Nicola Bianchi, Yi Lu, Hong Song, Feb 17, 2021We examine the effect of computer-assisted learning on students’ long-term development. We explore the implementation of the largest ed-tech intervention in the world to date, which connected China’s best teachers to more than 100 million rural students through satellite internet. Exposure to the program improved students’ academic achievement, labor performance, and computer usage for at least ten years after program implementation. These findings indicate...
Leverage-Induced Fire Sales and Stock Market Crashes
Jiangze Bian, Zhiguo He, Kelly Shue, Hao Zhou, Dec 03, 2018The authors find that margin investors heavily sell their holdings when their account-level leverage edges toward the maximum leverage limits. Stocks that are disproportionately held by accounts close to leverage limits experience high selling pressure and abnormal price declines that subsequently reverse over the next 40 trading days. Unregulated shadow-financed margin accounts contributed more to the market crash even though these shadow accounts had higher leverage limits and held a smaller fraction of market assets.
School Enrollment Restriction on Migrant Children and Human Capital Losses
Zibin Huang, Nov 24, 2021In China, migrant children are at a disadvantaged and sometimes cannot enroll in public schools in migration destinations due to policy restrictions. Some migrant workers then have to leave their children behind in their hometowns, which causes the left-behind children problem. This study finds that if the enrollment restriction on migrant children is relaxed, migration of parents and children will increase, and the average human capital in the society will also increase. Low-skill families from small cities benefit most.
The Collateral Channel of Monetary Policy: Evidence from China
Hanming Fang, Yongqin Wang, Xian Wu, May 13, 2020As a quasi-natural experiment to estimate the causal impact of the collateral-based unconventional monetary policy, we exploit the expansion of the collateral for the Medium-Term Lending Facility (MLF) in the interbank bond market on June 1, 2018 by the People’s Bank of China. We also consider that many bonds are dual-listed in a largely segmented exchange market. We find that the policy reduced the spreads of the newly collateralizable, dual-listed bonds in the treatment...
BigTech Lending as a New Form of Financial Intermediation
Jon Frost, Leonardo Gambacorta, Yi Huang, Hyun Song Shin, Pablo Zbinden, Jun 19, 2019BigTech firms, i.e. large technology firms whose primary business is digital services, are entering finance. Their entry into finance started with payments. Increasingly, they have expanded beyond payments into the provision of credit, insurance, and toward savings products, either directly or in partnership with incumbent financial institutions...
