Despite concerns about the economic impact of population aging, this study highlights the potential for a ‘silver dividend’ as longer lifespans extend working lives. We show that the effects of aging on growth are highly nonlinear and concentrated in more advanced, older economies. Labor shortages are often offset by rising labor force participation, particularly in countries with higher life expectancy, stronger human capital, and greater trade openness. Larger governments, measured by consumption, appear to cushion the effects of aging, while high-tax economies face more severe challenges. We offer policy insights to help mitigate the economic consequences of aging.
