  • A data-driven typology of individually perceived workplace environments and employee well-being

    Xie, J., Piao, X., & Managi, S.

    Scientific Reports   15 ( 1 )   2025.09  [Refereed]

    Academic Journal  Multiple authorship

    This study adopts a data-driven, employee-centered approach to explore how individually perceived workplace environments shape well-being. Analyzing over 1.3 million observations from 2017 to 2021, we identify nine key job demand and resource factors—including workload, emotional burden, job autonomy, organizational integrity, and support—using factor analysis. Rather than examining these dimensions in isolation, we apply Gaussian mixture models (GMM) to uncover ten distinct workplace types that reflect co-occurring patterns of demands and resources as experienced by individual employees, ranging from Grade D (least favorable) to Grade A1 (most favorable). Our findings reveal substantial variation in employee well-being—including mental health, work engagement, job satisfaction, and workplace cohesiveness—across these clusters. We further examine how changes in workplace type over time relate to changes in individual well-being, highlighting the importance of dynamic and subjective workplace conditions. By centering the employee perspective and identifying lived patterns of workplace experience, this study offers novel insights into workplace dynamics and supports more responsive, employee-oriented organizational policies and practices.

  • Altruistic behavior for environmental conservation and life satisfaction: evidence from 37 nations. Environment

    Piao, X., & Managi, S.

    Environment, Development and Sustainability     2025.07  [Refereed]

    Academic Journal  Multiple authorship

    Humanity’s economic activities are believed to be crucial factors in the deterioration of the world’s natural environment, including biodiversity loss and climate change. While the pro-environmental behavior of donors or volunteers may contribute to environment conservation and reducing consumption, its relationship to life satisfaction is still inconclusive. This study, which used original web-based cross-sectional microdata collected from 37 countries on six continents based on an ordered logit model, was conducted to confirm the association between donation and volunteer activities for environment conservation on individuals’ level of life satisfaction. We find that donations and volunteer activities for environment conservation positively affect individuals’ level of life satisfaction. Compared to volunteer attendance, cash donation appears to have greater positive effects on the level of life satisfaction. Citizens who participated in the multiple dimensions of donation (goods or cash) and volunteer activities for natural environmental conservation had a higher likelihood of satisfaction in 27 out of 37 countries: Brazil, Chile, China, Colombia, France, Germany, Greece, India, Indonesia, Italy, Japan, Malaysia, Mexico, Mongolia, Philippines, Poland, Russia, Singapore, Spain, Sri Lanka, Sweden, Thailand, Turkey, United Kingdom, United States, Venezuela, and Vietnam. The positive relationship between household income and life satisfaction was confirmed in 33 out of 37 countries. When regulating policies, we recommend that the United Nations utilize international citizens’ altruistic behavior for environmental conservation to benefit this type of conservation.

  • The Effects of Diagnosis-Related Groups Policy on Medical Care System Sustainability in China.

    Hu, Q., Lei, Y., & Piao, X.

    SAGE Open     2025.04  [Refereed]

    Academic Journal  Multiple authorship

    The well-organized medical security system plays an important role in improving public health. This study investigates the effect of the diagnosis-related groups (DRG) policy, which is a way to control cost, on medical care services, including hospital revenue status. Based on the panel data on derived from public medical institutions in Sanming City from 2014 to 2022, the average length of stay for discharged patients, number of admissions per 100 visits, and bed utilization rate were used to measure medical services status. The difference-in-difference method was used to explore the impact of the DRG policy implementation on the overall hospital operation in medical care services in Sanming City, China. We found the DRG policy introduction has a negative effect on the average length of stay for discharged patients, emergency admissions per 100 visits, and the hospital bed occupancy rate. On the contrary, the DRG policy reduces the total medical revenue in terms of the reduced drug revenue. However, the DRG policy increases the examination and the test income, average charge per emergency visit, and drug cost per discharged patient. In sum, the introduction of the DRG policy reduces the medical care system operating cost by reducing drug revenue and bed occupancy, reducing the length of hospitalization, worsening hospital revenue, and increasing the charge for examination and test, emergency visits, and drug cost per discharge. The C-DRG policy implementation in Sanming city effected improvements in public health and overall medical care system services.

  • Human capital and regional disparities: Advancing accounting frameworks with education, health, and population dynamics.

    PloS one     2025.03  [Refereed]

    Academic Journal  Multiple authorship

    This study advances the inclusive wealth accounting of human capital (HC) to improve global research on the valuation of HC for sustainability. By innovatively integrating complex population dynamics, including schooling and labor force participation, and using a net present value (NPV) valuation method aligned with capital budgeting principles, we quantitatively measure HC in 165 countries. As a methodological advancement, we use a unified framework that incorporates education, health and economic participation via the measurement of life expectancy in different life stages to inform sustainable development investments. Our analysis from 1990 to 2020 reveals significant differences in HC development across countries. While education is strongly correlated with GDP growth, disparities in health and economic participation are critical barriers to long-term HC accumulation. Our findings argue for a comprehensive policy approach that goes beyond investing in education for its financial benefits and includes substantial improvements in health and economic opportunities to promote more equitable HC growth. We emphasize the need to incorporate complex population dynamics into HC assessments to better understand and strengthen the interdependencies between these critical factors, with the aim of reducing global development gaps.

  • Continuous worsening of population emotional stress globally: universality and variations.

    Xiangdan Piao, Jun Xie & Shunsuke Managi

    BMC Public Health ( Springer nature )  24 ( 1 ) 3576   2024.12  [Refereed]

    Background
    Understanding emotional stress stability in populations is crucial because stress is a key factor in causing depression, and it worsens well-being.

    Method
    In this study, using repeated cross-sectional data from 149 countries from 2007 to 2021 (N = 2,450,043), we examined time trends of psychological stress in populations worldwide.

    Results
    Over half of the population experienced emotional stress in 20 countries, and 85% of the countries reported worse psychological stress in 2020 compared with 2008. We found that psychological well-being declined most rapidly among young people compared with other age groups. Individuals living and working in all types of locations (rural/farm, town/village, large city, and suburban areas) and employment (full-time, self-employed, part-time, and unemployed), respectively, experienced continuously worsening emotional stress when comparing three time periods (2008–2011, 2012–2019, and 2020–2021). Furthermore, reducing physical pain and increasing income were noted to be more important than solving health problems for the purpose of decreasing stress.

    Conclusion
    Emotional stress continuously worsened worldwide over the past few decades, but the trend varied among countries. Our findings highlight the significance of improving people’s living environments to reduce their likelihood of experiencing emotional stress.
