E-book New Models for Managing Longevity Risk : Public-Private Partnerships
There are now half a million centenarians in the world, and their num-ber is projected to grow eightfold by 2050 (Stepler 2016). Inevitably, longerhuman lifespans, especially at older ages, are reshaping how we must thinkabout work, planning, saving, investing, insuring, and financing our liveli-hoods in retirement. This volume offers a perspective on how public-privatepartnerships (PPPs) can play an important role in enhancing retirementsecurity.Such partnerships generally involve a governmental organization col-laborating with private sector firms to provide needed goods and services,in ways that neither party could likely achieve on its own. Typically, PPPsinvolve government financing, while the private sector partner providesexpertise, management responsibility, and accountability.1This book cap-tures perspectives from experts in the field to explore how governmentsand the private sector can be tapped to provide and enhance retirementsecurity along several dimensions. In addition to empirical evidence, ourcontributors detail case studies, discuss survey results, and examine a vari-ety of different financial and insurance products to better meet the needsof the aging population. Here we define longevity risk as the chance that someone will outlive hisor her retirement resources, potentially to fall into old-age poverty. Onereason people may be vulnerable to such risk is that they might not under-stand the chances that they will live to older ages. In such an eventuality,workers might underestimate how much they need to save for retirement,and retirees could overestimate how much they can spend from their sav-ings. In such circumstances, peoples’ expectations about longevity as wellas disability-free longevity could lead to suboptimal behavior.
