Distributional Consequences of Hospital Heterogeneous Responses to a Blended Payment Scheme Reform

with Wei Yan, Junjian Yi, and Chuanchuan Zhang, under review

Many hospital payment schemes are designed to control health expenditure, but they could also influence the allocation of medical resources, which is crucial for efficient healthcare delivery. This paper studies the effects of hospital responses to a blended payment scheme—a diagnosis-based payment scheme with a global budget—and the distributional consequences of hospital heterogeneous responses. Exploiting a quasi-experimental reform in China in 2016, we find hospitals responded along multiple dimensions: upcoding, raising the shares of admissions in categories with higher upcoding potential, and increasing the total number of admissions. Hospitals’ heterogeneous responses led to a widened disparity in hospital payments, which is mainly driven by heterogeneous upcoding across hospitals. Hospitals with more knowledge about coding practices, greater exposure to the reform, higher tier, and larger size respond more strongly to the reform, therefore securing a larger portion of the global budget from the social health insurance fund.



Interpreting “Aging in Place” and “Aging Well” through the Elder Care Model in Two Senior Apartments in China

with Xiaoyan Lei, Xuanyi Nie, and Winnie Yip


With China's rapidly aging population, the need for innovative eldercare models that support both longevity and quality of life has become increasingly urgent. This study examines the interplay between "aging in place" and "aging well" within the context of senior apartments in China, focusing on two pioneering examples: Taikang Home · Chu Garden and Xianghe · Da’ai City. This research adopts a qualitative approach, employing semi-structured interviews with residents, service team members, and management team members to explore how these senior apartments facilitate aging in place and contribute to the well-being of their elderly residents. The findings reveal that these apartments are well-equipped to address both the physical and emotional needs of the elderly, offering comprehensive medical care, age-friendly facilities, and a supportive social environment. Key to this success is the integration of healthcare services within living facilities, the use of smart technologies for safety and convenience, and a strong emphasis on community and social engagement. However, the study also identifies challenges, such as ensuring sufficient personal companionship and managing diverse resident lifestyles, suggesting areas for further policy and practice improvement. This research contributes to the literature on aging by integrating the concepts of aging in place and aging well, offering insights into how physical and social environments can support the elderly, and suggesting novel concepts that could be multiplied elsewhere.



Getting Urgent Health Care in Time: The Impact of China’s Poverty Alleviation Program 

with Xiaoyan Lei and Ang Sun, under review


This paper estimates the impact of the 8-7 National Plan for Poverty Reduction, a large-scale poverty alleviation program in China during 1994–2000, on the mortality rate from cerebrovascular diseases. The rollout of the program after 1994 was mainly based on whether the average income per capita of a county fell below a certain cutoff, which allows for the design of a combination regression discontinuity and difference-in-differences approach. Using data collected from the National Disease Surveillance Points system, the analysis suggests that the poverty alleviation program decreased the cerebrovascular disease mortality rate by at least 28.0%l, which is mainly attributed to the construction of local health centers under the poverty alleviation program. The analysis finds that the reduction in mortality was mostly due to fewer deaths at home. Other aspects of the program, such as road construction, also likely played a part in the reduction in mortality from cerebrovascular diseases.



Do Actual Caregivers Meet Expectations? Motivation, Behavior, and Impacts of Informal Care to Parents 

with Yaohui Zhao


This study aims to investigate the gap between expected and actual caregivers of parents in need of care and its impact on care receivers. Using panel data from the four waves of the nationally-representative China Health and Retirement Longitudinal Study (CHARLS), we employ a family fixed-effects linear probability model to examine the characteristics of expected and actual caregivers of individuals aged 45 and above who experienced functional impairment between 2011 and 2018. Our results suggest that 38.44% of men and 41.79% of women have at least one actual caregiver who met their earlier expectations. Regarding caregivers, the division of labor among siblings for supporting parents through economic transfer and in-person care depends on their opportunity cost of caring. Children who are not actual caregivers of their parents are more likely to provide economic support. Our findings imply that parents’ behaviors toward economic support align more with the altruism motivation, whereas their behavior toward providing care aligns more with the exchange motivation. Furthermore, women who reside in self-owned properties may have greater leverage in selecting their preferred caregivers. As a result, being taken care of by expected caregivers significantly enhances parents’ positive emotions toward life, especially for women.



Life Expectancy, Population Ageing, and Economic Growth (预期寿命、人口老龄化与经济增长)

with Gordon Guoen Liu and Nan Xiao, under review


To investigate the impact of increased life expectancy on economic growth and its mechanism, this paper develops a growth model that captures

human capital and physical capital accumulation, in which life expectancy depends on the government’s health investment and contributes to the utility function. Using panel data from 127 countries over 1970-2019, this paper discovers that the increased life expectancy is positively correlated with the growth rates of human capital and physical capital, and the latter is especially salient in low- and lower-middle-income countries. Further research by periods reveals that since 1985, only low- and lower-middle-income countries benefited from the increased life expectancy in terms of GDP per capita growth rate, and it became a restrictive factor of economic growth for high- and upper-middle-income countries after 2000. Meanwhile, population aging slows down economic growth in general, but it contributes to the proportion of tertiary industry in GDP.
