This is the third publication to analyze progress, challenges, and adjustment options of this reform revolution for mandated public pension schemes. The individual account-based but unfunded approach that promises fair and financially sustainable benefits is a reform benchmark for all pension schemes. Nonfinancial defined contribution (NDC) schemes originated in the 1990s independently in Italy and Sweden, were then adopted by Latvia, Poland, and Norway, envisaged but not implemented in various other countries (such as Egypt and Russia), and remain under discussion in many countries across the world (such as China and France).

Volume 1 offers an assessment of early reform countries before addressing key aspects of policy implementation and design review, including: how to best combine basic income provisions with NDC; how to deal with heterogeneity in longevity; and how to adjust NDC design and labor market policies to deliver on reform expectations.
