Physician-Induced Demand: Evidence from China’s Drug Price Zero-Markup Policy

Hanming Fang, Xiaoyan Lei, Julie Shi, Xuejie Yi, Aug 11, 2021

We 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.

Economic Growth — in the World and in China

Robert J. Barro, Jul 12, 2017

Convergence forces suggest that China’s per capita GDP growth rate will decline gradually from around 7% per year to the world’s historical average of 2%.

The Effect of Computer-Assisted Learning on Students’ Long-Term Development

Nicola Bianchi, Yi Lu, Hong Song, Feb 17, 2021

We 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...

The Data Privacy Paradox of Alipay Users

Long Chen, Yadong Huang, Shumiao Ouyang, Wei Xiong, Jul 07, 2021

We find that there is no relationship between the self-stated privacy concerns of a sample of Alipay users and their number of data-sharing authorizations with third-party mini-programs on Alipay. We explain this data privacy paradox by a curious finding that users with stronger privacy concerns tend to benefit more from using mini-programs, which further suggests that consumers may develop data privacy concerns as a by-product of the process of using digital applications, not because such concerns are innate.
