Millennials Will Pay the Price: Demographic Imbalance and Reform Inertia in Canada’s and Spain’s Pension Systems

This paper examines how demographic imbalance and policy inertia undermine intergenerational equity in Canada’s partially funded and Spain’s pay-as-you-go pension systems. Despite structural differences, both nations transfer financial risks to Millennials and Gen Z due to aging populations, low fertility, and political resistance to reform. Using a comparative political economy framework and a stylized hyperbolic discounting model, the study shows institutional design alone cannot prevent unsustainability when incentives favor short-term gains. Policy recommendations include automatic adjustment mechanisms, independent fiscal councils, and private pension incentives.
