Healthy Longevity as Regenerative Capital: AI-Enabled Prevention, Senior Re-employment, and Climate Risk
By Jules SADEFO KAMDEM Population ageing and climate change jointly threaten the functional capacity that sustains autonomy, labour supply, productivity, and fiscal resilience. This paper develops a continuous- time, age-structured model in which healthy longevity is a regenerative form of human capital. Cohort health is exposed to biological depreciation, a standardised heat-stress state, diffusion risk, and marked compound-Poisson losses. Prevention, climate adaptation, education, and effectively accessible artificial intelligence can offset avoidable depreciation. AI is accumulated as a depreciating capital stock...
