Income Inequality among Old Chinese
Katja Hanewald, Ruo Jia, Zining Liu, Oct 16, 2019Using data from the China Health and Nutrition Survey (CHNS) from 1991–2015, we decompose the income inequality among old Chinese and compare the income inequality between old households and young households. We develop an OLG model and a new empirical method to test how initial socioeconomic differences transmit to income inequality in the working years and then in old age. We find that the urban-rural gap and educational differences...
Does Good Luck Make People Overconfident? Evidence from a Natural Experiment in China
Huasheng Gao, Donghui Shi, Bin Zhao, Aug 01, 2018We find that retail investors who win an allotment for an IPO subscription subsequently become more overconfident relative to retail investors who do not have an allotment. The former group subsequently trades more frequently and loses more money. Overall, our evidence indicates that the experience of good luck makes people more overconfident about their prospects.
The Effect of Pollution and Heat on the Productivity of High-Skill Public Sector Workers in China
Matthew E. Kahn, Pei Li, May 22, 2019The quality of governance depends on public sector worker productivity. We use micro data from China to document that judges are less productive on polluted days. We find that public sector productivity elasticities are larger than the published estimates of private sector productivity elasticities with respect to pollution.
The Impact of Rapid Aging and Pension Reform on Savings and the Labor Supply: the Case of China
Hui He, Lei Ning, Dongming Zhu, Jun 26, 2019Individuals can use savings and labor supply to self-insure against uncertainties over their life cycle, such as idiosyncratic income shocks and changes in longevity and pension benefits. Using China as a case study, we investigate, both empirically and quantitatively, the impact of rapid aging and pension reform on savings and the labor supply, and the roles...
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.
