Social Security faces a major financing shortfall. One policy option for addressing this shortfall would be to raise the earliest age at which individuals can claim their retirement benefits. A welfare analysis of such a policy change depends critically on how it affects living standards. This...

The paper provides a framework for the conceptualization, definition and estimation of legacy costs that need to be addressed in a reform that transforms an unfunded defined contribution (NDB) scheme into a notional (or non-financial) defined contribution (NDC) scheme. As the new contribution...

There exists a wide variety of tax treatments of pensions across the world. And the reasons for such a range of regimes are not clear. This note reviews the general principles of pension taxes and analyses the theoretical foundations of why pension incomes ought to be taxed specifically. To do...

Heterogeneity in longevity between socioeconomic groups is increasingly documented for developed economies and is reviewed in the paper. Heterogeneity in life expectancy disaggregated by main socioeconomic characteristics - such as age, gender, race, health, education, profession, income, and...

Across the world, pension systems and their reforms are in a constant state of flux driven by shifting objectives, moving reform needs, and a changing enabling environment. The ongoing worldwide financial crisis and the adjustment to an uncertain “new normal” will make future pension systems...

This paper demonstrates that the link between heterogeneity in longevity and lifetime income across countries is mostly high and often increasing; that it translates into an implicit tax/subsidy, with rates reaching 20 percent and higher in some countries; that such rates risk perverting...

The importance of cross-border portability of social benefits is increasing in parallel with the rise in the absolute number of international migrants and their share of the world population, and perhaps more importantly, with the rising share of world population that for some part of their life...

Population aging is typically associated with economic challenges for productivity and financial threats for the old-age financial protection system of a country. This paper takes an optimistic position and outlines key ingredients to make it a successful experience. Yet to turn this challenge...

We study the design of pension benefits for male and female workers. Women live longer than men but have a lower wage. Individuals can be single or live in couples who pool their incomes. Social welfare is utilitarian but an increasing concave transformation of individuals' lifetime utilities...

In many policy areas it is essential to use the best estimates of life expectancy, but such estimates are vital to most areas of pension policy - from indexed access age and the calculation of initial benefits to the financial sustainability of pension schemes and the operation of their...
