  • Work Hour Mismatch on Life Evaluation: Full Heterogeneity and Individual- and Country-Level Characteristics of the Most and Least Affected Workers.

    Mismatches between workers’ actual and preferred hours of work are ubiquitous and have detrimental effects on well-being. Yet, the full heterogeneity of these effects and the characteristics of the most and least affected subpopulations remain largely unknown. This study collects survey data from 37 countries and estimates the full heterogeneity in the effects using a newly developed method—the sorted partial effect method. Based on the full heterogeneity, we employ classification analyses on the 10%-most and 10%-least affected groups and show that individuals most (vs. least) affected by overemployment are younger, while those most (vs. least) affected by underemployment are older. Age is the most influential factor that distinguishes the most and least affected workers when compared with other individual-level factors such as education level, household income, and the number of children. Country-level differences between the most and least affected groups imply that work hour mismatch is more tolerable for workers in relatively poorer countries than for workers in wealthier countries. These findings underscore age-tailored policy responses for alleviating the negative effects of work hour mismatch and provide insights for understanding the complex economic preferences across countries.

  • Lessons on the COVID-19 pandemic: who are the most affected

    The COVID-19 pandemic has led to significant changes in work and lifestyle, impacting occupational mental health. This study examines the time and individual heterogeneity in the pandemic's effects on occupational mental health using panel data from job stress checks spanning 2018 to 2021. On average, there was an initial alleviation of high-stress risk in 2020, followed by a deterioration in 2021. Based on the job demand-resource theory, we identify the group of employees most affected by the pandemic. The findings highlight that employees in unfavorable workplace conditions are more likely to experience substantial adverse impacts. Adequate workplace support, including factors like interpersonal relationships, managerial support, job meaning, control, and work-life balance, is crucial for mitigating high-stress risk. Additionally, during the early phase of the pandemic, engaged employees experienced a slight decline in occupational mental health, while those lacking job resources at their worksite faced higher levels of occupational stress in the subsequent year. These findings offer practical suggestions for person-centered coping strategies to mitigate the pandemic's adverse impact.


  • The international role of education in sustainable lifestyles and economic development

    Improved economic growth and environmental protection are necessary to achieve the United Nations’ Sustainable Development Goals. This study examines the relationship between people’s education levels and sustainable lifestyles in protecting the environment and economic growth, as expressed by the increase in household equivalent income. We conducted an original cross-sectional survey, which yielded 100,956 valid observations in 37 countries. The factors included educational level, sustainable lifestyle with natural resource consumption, and household equivalent income for economic development. We used logit and ordered logit model and applied an ordinary linear regression model after confirming the association between education and income. Our analyses found that higher educational levels were associated with an increase in specific environmentally friendly behaviors and sustainable energy consumption. Individuals in the higher educational level group tended to consume recycled goods, purchase energy-saving household products, conserve electricity, and separate their waste. Additionally, higher levels of education were positively associated with equivalent household income in all 37 countries, indicating better economic development. Thus, our study underscores the importance of improving education at the broad population level to promote economic development and establish cooperative human behaviors necessary to sustain the environment.


  • Intra-Household Income Management and Couple’s Relative Sharing of Income and Environment Sustainability in Japan

    This study aims to identify household members’ income sharing, when the amount of said income is governed by a particular household member. The results are expected to provide insightful evidence that identifies who is under the poverty line within families. This will illustrate the intra-household allocation inequality by observing the members’ household income dominance. Using the information on household income management obtained from the Japanese Household Panel Survey data (1993–2013) and the original Internet survey, this paper develops an alternative methodology to estimate the household income distribution of couples. A two-step estimation process was employed to estimate the wife’s manageable income equation. Then, the parameters were substituted into the husband’s manageable income equation to estimate the parameters for calculating the wife’s sharing rule. The results are as follows. First, a wife’s share of intra-household resources positively correlates to her manageable income resources. However, wives have weak power in expending the transferred income from their husbands. Second, the remarkable feature is that, on average, wives share 37% of the resources, meaning that the wives’ relative bargaining is weaker than the husbands’. Narrowing the gap in terms of hourly wage between husbands and wives is a crucial tool to reduce the intra-household allocation gap. Third, the wives’ relative intrahousehold income allocation improvement is associated with household environment sustainability activities. To improve the intra-household income allocation inequality, we provide an original approach to explore the intra-household head of household members’ relative income sharing. The results highlight the inequality of intra-household income distribution and confirm that reducing the income gap would be a crucial improvement factor.
