Description: This is a review of 'Restructuring Retirement Risks,' a collection of papers that examines retirement risks, edited by David Blitzstein, Olivia Mitchell, and Stephen Utkus. The papers, which are a must–read for serious students of retirement systems and a good introduction for those not as familiar with the issues, explore the stresses being placed on those systems and ever–increasing uncertainty as Baby Boomers begin to move into retirement.
