However, the relative risk of reporting unmet need rose, particularly among ethnic minorities, individuals with musculoskeletal and mental health conditions, and those not in work or retirement (due to long-term sickness or disability, home or family responsibilities, or unemployment). Individuals living alone and those aged 50–59 faced higher unmet needs for home care, but maintained primary care access as opposed to their counterparts.

In 2007, the National Pension was reformed to gradually lower the income replacement ratio from 60 % to 40 %. The Korean government implemented the Basic Old-Age Pension (BOAP) to compensate for the loss in pension income in 2008. While the BAOP benefits mitigate income poverty, it may also have spillover effects on social activities and health outcomes that older people are likely to be deprived of. We use the 2006–2020 Korean Longitudinal Study of Aging for the analysis. Using a doubly robust difference-in-differences model and event study, we investigate the impact of BOAP on social engagement and the health of older people. The results show that BOAP recipients tend to have more frequent meetings with children and are likely to have a better relationship with children while they are less likely to participate in social groups and have fewer social group meetings. These results are more evident among those recipients who have received pension benefits for longer years. We find a greater positive impact of BOAP on the health of non-employed, non-married, and poor recipients and the social activities of women, employed, and non-poor recipients. The impact of BOAP may vary by gender, employment status, marital status, and poverty status but the overall results emphasize the continual assistance of BOAP in promoting the social engagement and health of older Koreans.</div></div>","PeriodicalId":45848,"journal":{"name":"Journal of the Economics of Ageing","volume":"31 ","pages":"Article 100566"},"PeriodicalIF":1.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143838313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional measures of health status are insufficient for understanding how labor supply outcomes are influenced by the match between individuals’ abilities and job demands. We use unique survey data on individuals’ self-reported ability levels, harmonized with occupational ability requirements from the O*NET database, to develop a new measure of work capacity. We find that average abilities overall and across different domains are high relative to average occupational demands. At the same time, age-related declines in abilities are modest, at least through age 70. Putting these elements together, individuals’ work capacity is relatively stable with age. Finally, we show that our measures of work capacity are predictive of current and expected future labor supply outcomes, with and without controls for standard health variables.</div><div>This research was supported by grant number UM19-02 from the U.S. Social Security Administration (SSA) through the Michigan Retirement and Disability Research Center (MRDRC) and by grant number R01AG056239 from the National Institute on Aging.

Our measure includes 15 indicators spanning seven dimensions: social connectedness, knowledge, health, employment and social protection, shelter, water and sanitation, and energy. We set a referential threshold that identifies an older individual as multidimensionally poor if they experience deprivations in at least three out of seven dimensions of our measure. Our results show that multidimensional poverty incidence among older people in Peru has decreased by 8.6% between 2018 and 2023 but remains high at 35%. Older women, older people living in rural areas, older indigenous people and older people with disability are multidimensionally poorer than their counterparts, with deprivations contributing the most to multidimensional poverty varying across subgroups and subnational regions. Our findings can guide policymakers in prioritising resource allocation by identifying key deprivations to reduce multidimensional poverty among older adults. We estimate that 23% of the older population experience multidimensional but not monetary poverty, highlighting the complementarity of these approaches. Additionally, we find 12% of older people living in multidimensional and monetary poverty simultaneously, rising to 30% in rural areas. Our study bridges the most up-to-date conceptual and empirical literature on multidimensional poverty with the literature on poverty measurement in older age in low- and middle-income countries.</div></div>","PeriodicalId":45848,"journal":{"name":"Journal of the Economics of Ageing","volume":"31 ","pages":"Article 100563"},"PeriodicalIF":1.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143799919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
