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.

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.

Major video and live streaming platforms in China have recently introduced a live commenting feature that allows viewers to post comments in real time during video content consumption. Building on the rich live comment data, this research proposes a novel approach for in-consumption social listening to extract live consumption experience. The approach is demonstrated in the context of online movie watching...

Optimising Production: Industrial Policies in Networks

Ernest Liu, Mar 13, 2019

Many developing countries adopt industrial policies favoring upstream sectors. Liu (2018) shows these policies might enhance aggregate production efficiency. When sectors form a production network, market imperfections generate distortions that compound through input demand linkages, accumulating into upstream sectors and creating an incentive for...
