Saving through consumption uses advances in financial technology and behavioral science to encourage people to save for retirement, and can alleviate the increasing costs of longevity for the Portuguese pension system. This paper provides an introduction to multi-pillar systems, an overview of the Portuguese pension system, followed by the challenges this system faces related to its long-term sustainability. Afterwards, we introduce the behavioral science behind saving through consumption, along with how it has been successfully implemented in countries like Mexico and Spain. In the final section, we provide a brief proposal of how savings through consumption could be introduced in Portugal, and simulate the additional retirement savings this proposal can represent for an average household.
