The impacts of different dietary restriction regimens on aging and longevity: from yeast to humans

By Tsui-Ting Ching & Ao-Lin Hsu Dietary restriction (DR) refers to a broad set of interventions that limit the intake of specific nutrients or overall food consumption, either in quantity or timing, without causing malnutrition. DR has long been considered the most robust intervention for increasing healthspan and lifespan. This includes, not exhaustively, caloric restriction (CR), protein restriction (PR), amino acid restriction (AAR), intermittent fasting (IF), and time-restricted fasting (TRF), each with overlapping but distinct metabolic and physiological effects. This...

The U.S.-Born labor force will shrink over the next decade

By Josh Bivens It is often underrecognized how much population aging is currently reducing the growth rate of the U.S. labor force and will continue to pull it down in coming decades. The share of the population that is over the age of 65 (when labor force participation tends to take a steep fall on average) is rising rapidly. This share was 12.4% in 2007, 17.9% in 2024, and will hit 21.2% by 2035 (CBO 2025b). A recent EPI report...

Pension Design and General Public Finances: Beyond Baseline Actuarial Neutrality

By Didier Blanchet & Gilbert Cette The design of pension benefits cannot be considered in disconnection from the constraints related to the general public finances. A change in the average retirement age has an impact not only on pension funding, but also on resources available for other public spending. Incorporating this externality implies penalties/bonuses for earlier/later retirement that are much higher than those designed to balance the pension system alone. Source SSRN

Part-Time Penalties and Heterogeneous Retirement Decisions

By Kanta Ogawa Older male workers exhibit diverse retirement behaviors across occupations and respond differently to policy changes, influenced significantly by the part-time penalty—wage reduction faced by part-time workers compared to their full-time counterparts. Many older individuals reduce their working hours, and in occupations with high part-time penalties, they tend to retire earlier, as observed in data from Japan and the United States. This study develops a general equilibrium model that incorporates occupational choices, endogenous labor supply, highlighting that the...

Population Aging in ASEAN+3: But is 60 the New 40?

By Aruhan Rui Shi & Hongyan Zhao Population aging is becoming a significant concern, particularly as its pace accelerates, especially in emerging market economies. However, labeling all individuals aged 65 and above as elderly can be misleading and inaccurate when life expectancy is increasing. Therefore, using the prospective old-age dependency ratio to define what is elderly would allow for more precise measurements and facilitate research into the impact of aging on economic growth. Our findings suggest that while a negative...

Specifically, this paper identifies 3 areas of public health concern that are inflamed by the conflict in Ukraine that will likely have an outsized effect on the economic success and political legitimacy of the country in the coming years. These are, namely, alcohol addiction, an aging population, and attrition from...

Optimization Algorithms for Pension Asset Allocation Under Market Volatility

By Akshay Sharma & Satish Kabade Pension fund organizations function as essential financial entities that protect employee retirement funds to provide complete and punctual pension distributions. Pension fund effectiveness through asset distribution determines how well a fund meets its future obligations. Traditional methods of portfolio optimization align with the Modern Portfolio Theory through the Markowitz model to help determine asset allocation by defining the relationship between return and risk. These static modeling approaches fail to fulfill their purpose in real...

Has Population Aging Led to Strategic Shifts in Enterprises?

By Hanteng Li, Yun Qin & Yuhang Wang  This paper uses Chinese listed companies from 2009 to 2023 as a sample to systematically examine the impact pathways and mechanisms through which population aging influences corporate strategic transformation. The study finds a significant positive relationship between population aging and corporate strategic transformation, and this conclusion remains robust under multiple sensitivity tests. Further analysis of moderating effects indicates that a firm’s innovation capability plays an important moderating role in the relationship between...

The Impact of Job Exposure to Artificial Intelligence on the Korean Labor Market in 2020

By Yeseul Lee & Hyeonjun Hwang This study examines the impact of artificial intelligence exposure on wage and employment outcomes in the Korean labor market in 2020. We propose the Artificial Intelligence Exposure Score (AIES) by integrating 27,921 Korean AI patents from 2011 and 2020 with O*NET task descriptions through Sentence-BERT natural language processing techniques. This approach creates occupation-level exposure measures that reflect Korea-specific innovation patterns. Using data from the Korean Labor and Income Panel Study (KLIPS), we estimate log-linear...

Commuting Time, Flexibility, and Job Security

By Bert van Landeghem, Thomas Dohmen & Arne Risa Hole We analyse workers’ preferences for wages, commute time, working-from-home, flexibility, job security, and social impact using discrete choice experiments from 2022 and 2025 with about 4,000 Flemish employees. Preferences for shorter commutes and flexible schedules remain stable post-pandemic, with substantial willingness-to-pay (WTP) for these attributes. However, WTP for job security declined and the value of socially impactful jobs disappeared by 2025. Latent class analysis identifies distinct groups differing in their...
