A sustainable, variable lifetime retirement income solution for the Chilean pension system

Defined contribution retirement pension systems need to improve the level and stability of payments as pensioners age. Longevity risk pooling is key, but so is flexibility to satisfy members' individual needs and preferences. We propose a tontine construct as a flexible and cost-effective investment option for the Chilean pension system. Payouts are for life, but variable since there are no explicit guarantees. Our proposal provides transparency, investment flexibility, and higher expected income streams than any of the existing options available to the country’s pensioners. Importantly, it does not distort the existing investment and annuity markets; on the contrary, it complements them. Additionally, it provides a means to offer a form of longevity insurance even if insurers are unwilling to supply it. Furthermore, it is in line with the movement of many countries toward promoting longevity-risk sharing within their defined-contribution systems.
