This paper explores the introduction of collective risk-reallocation elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset-contingent arrangements to reallocate risk among participants. Eliminating asset market risk for the retired raises...

Differences in life expectancy between high and low socioeconomic groups are often large and have widened in recent decades. In the United States, the differences may now be as large as ten to fourteen years. These longevity gaps strongly affect the actuarial fairness and progressivity of many...

This paper identifies and discusses four issues in creating annuities in (nonfinancial) defined contribution (NDC) schemes that are essential for systems' financial stability and fair inter or intragenerational redistribution. The first issue is the choice between incorporating the rate of...

For many pension schemes, a shortage of data limits their ability to use sophisticated stochastic mortality models to assess and manage their longevity risk. In this study, we develop a relative model for mortality, which compares the evolution of mortality rates in a sub-population with that...

This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on fun ded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

Earlier claims that pensions serve as severance pay are corroborated by a new data set drawn from the 1980 Banker's Trust corporate pension plan study. A model is developed that shows how pension values which vary with the age of retirement make both workers and firms better off by moving the...
