  • Donations for environmental sustainability and subjective well-being: Evidence from 37 nations

    Xiangdan Piao,Shunsuke Managi

    Academic Journal  Multiple authorship

    This study investigates donations for environment sustainability and emotional well-being using a large-scale survey of 100,956 observations from 37 nations on 6 continents based on the internet and face-to-face methods according to goal framing theory. The relationship between individuals’ pro-environmental conservation behavior (donations and volunteerism) and positive and negative emotions was determined using an ordered logit model. We found that people engaged in donations (cash and goods) or volunteering had an increased likelihood of experiencing positive emotions and a reduced probability of experiencing negative emotions. Similarly, the results confirmed that 27 of 37 nations, including China, India, the United States and Japan. Donating for nature less than 9% of income was associated with a higher probability of positive emotional well-being and a lower likelihood of negative emotion. Worldwide institutions, such as the United Nations, have constructed new environmental conservation programs that may be an option for contributing to sustainability.


  • Occupational stress: evidence from industries affected by COVID-19 in Japan.

    This study provides objective evidence on the impact of COVID-19 based on employee occupational stress reported from 13 different industries, and examines the determinants of employee psychological well-being. As the economic and social impacts of the COVID-19 pandemic continue, governments should consider industry-level differences when making support decisions concerning public resource allocation to corporations. However, little evidence exists regarding the differences in occupational stress across industries.

    Employee occupational stress data (N = 673,071) was derived from workers in Japan from 2018 to 2020. The sample comprises workers from 13 industries, including civil services, service industry (other), real estate, medical/welfare, wholesale/retail, academic research, and accommodation/restaurant business. A logit model is employed to investigate the differences in employees’ psychological well-being before and during the pandemic.

    In 2020, 11 out of 12 industries had significantly worse occupational stress compared to employees engaged in civil services. Over 23% of employees from the wholesale/retail and accommodation/restaurant industries were observed as high-stress employees. Improved compensation policies supporting these industries are suggested. In contrast, reduced occupational stress was found among employees in the transportation/postal and information/communication industries. Among the 13 industries, aside from high job demands, tough inter-person relationships in the workplace became the most significant stressors during the pandemic.

    The results confirm that the pandemic has had a heterogeneous effect on employee occupational stress across industries, thus suggesting that the level of compensation given to different industries during the COVID-19 pandemic should be discussed and approved by the Japanese government. Additionally, support for the wholesale/retail and accommodation/restaurant industries during the pandemic should be improved.


  • The impact of cooling energy needs on subjective well-being: Evidence from Japan,

    Given the increasing energy needs for indoor cooling and the growing attention to energy poverty, it is important to understand how cooling energy needs in the hot summer season affect human well-being in relation to income level. Using Japan as a case country, this study examines how much energy consumption increases in response to higher temperatures in the summer season and how the additional energy needs for indoor cooling, in turn, affect subjective well-being (SWB). The results confirm that higher cooling energy needs can reduce SWB. In relation to income level, the lowest-income group faces the highest cooling energy needs, presumably due to lower energy efficiency in housing. In contrast, the negative effect of cooling energy needs on SWB is the largest for the middle-income group. This contradictory finding implies that behavioral aspects matter for the evaluation of SWB.


  • Natural Capital Exploration and Coronavirus Disease Spread in 2020.

    The potential relationship between nature and Coronavirus disease 2019 (COVID-19) is provided using cross-sectional macro-data collected including 17 countries of major developed and developing nations whose number of cases were greater than 500 in March 15th 2020. We found that the correlation coefficient is -0.46 between fisheries stock average growth rate per capita from 1994 to 2014 and number of COVID-19 cases in 2020. It suggests that the damage of lives under water and cases of COVID-19 might be associated.


  • Long-term improvement of psychological well-being in the workplace: What and how.

    The World Health Organization states that by 2030, mental illness will become the leading global disease burden. Thus, investigations of job stress might require more heterogeneous and innovative solutions. Existing literature demonstrates that good workplace environments have favorable effects on employees’ psychological well-being. However, studies on long-term effects are scarce. This study examined the long-term impact of comprehensive workplace characteristics and employee responses to stress (coping strategies) on job stress in Japan.

    Under a large-scale 3-year longitudinal study, 1,021,178 observations collected from employees in 390 companies from 2017 to 2019 were used. Employee job stress trends were confirmed based on company-fixed-effects linear regression. The relationship between one-year or two-year lagged comprehensive workplace characteristics or coping strategies, and employee job stress was estimated using linear regression. Favorable effects of the work environment and coping strategy improvement were illustrated based on the regression results simulation.

    First, job stress appeared to be steadily worsening among the employees of Japanese companies from 2017 to 2019. Second, low job and psychological demand, high job control, a high level of support from the people around, balanced effort–reward, strong job security, and strong interpersonal relationship have favorable long-term effects on employee job stress. Third, employees’ coping strategies, such as positive thinking, changing mood, requiring help from other people, reduced negative thinking, and avoiding inappropriate emotional divergence have long-term effects on mitigating job stress. Particularly, thinking positively, changing mood, and avoiding directing feelings of anger and frustration toward others reduce high stress in 46% of respondent employees.

    A comprehensive well-organized workplace environment and appropriate responses to stress have a long-term favorable effect on employee job stress. These results provide policy measures for improving the workplace environment and for employees to adopt coping strategies to enhance their psychological well-being in the long term.
