Physician-Induced Demand: Evidence from China’s Drug Price Zero-Markup Policy
Hanming Fang, Xiaoyan Lei, Julie Shi, Xuejie Yi, Aug 11, 2021We exploit the staggered rollout of China’s drug price zero-markup policy (ZMP) to study physician-induced demand in healthcare. Our results show that the drug expenses in the treatment hospitals dropped by 63 log points (47 percent) compared with those of the control group; however, the expenses for non-drug services were 28 log points (32 percent) higher in the treatment group than in the control group. Our results provide robust evidence for physician-induced demand.
Mortgage Prepayment in China
Zhenyu Gao, Wenxi Jiang, Haohan Ren, Kemin Wang, Yuezhi Wu, Sep 10, 2025During the 2019–2024 monetary easing cycle, Chinese households used their savings to prepay unprecedented amounts of mortgage loans. Because refinancing was restricted, mortgage rates remained rigid, while savings returns quickly adjusted to rate cuts. The widening gap between borrowing costs and savings returns encouraged prepayment (deleveraging) and reduced consumption. Our findings suggest that the rigid mortgage rates have rendered China’s monetary easing counterproductive.
How Liberalizing Trade with China Led to a Boom in International Students in the US
Gaurav Khanna, Kevin Shih, Ariel Weinberger, Mingzhi Xu, Miaojie Yu, Aug 16, 2023Focusing on China’s accession to the World Trade Organization, we show that Chinese cities with more exposure to trade liberalization sent more students to US universities.
Corporate Innovation and IPO Interventions
Lin William Cong, Sabrina T. Howell, May 20, 2020The Chinese government has occasionally suspended IPOs, exogenously creating uncertainty about access to public markets for firms already approved to list. We show that suspension-induced delay reduces corporate innovation activity both during the delay and for years after listing.
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.
