Dear Colleagues,

Many institutions are calling for public and private pension systems to be restructured. The OECD and the World Bank, among others, are advocating a remodeling of these systems. Classic solutions have not worked. Today, there is a threat of economic, demographic, and financial risks that threaten the sustainability of these systems. New problems such as longevity and ageing populations, economic deflation, negative returns, and the consequences of the COVID-19 pandemic make it necessary to manage and develop innovative pension models that are able to cope with these new social challenges.

This Special Issue of Mathematics (IF: 1,747) dedicated to high-quality articles that advance the state of the art with innovative theoretical, practical, and policy developments in modelling risks affecting public and private pension systems. Articles related to, but not limited to, the following topics are welcome:

• Sustainable design of both public and vested DB and DC retirement plans.
• Labor and social risks in the funded phase.
• Rate of return in the construction of the pension payout phase.
• Longevity and low-interest-rate risks in the pension payout period.
