THE 80% PENSION FUNDING TARGET, HIGH ASSUMED RETURNS, AND GENERATIONAL INEQUITY

摘要

Generational inequity in pension funding is highly sensitive to the lax policies of 80% funding targets and high assumed returns to investment. I develop a simple, powerful relationship between steady-state (SS) inequity in contributionsthe percent of extra contributions to fund prior cohortsand the SS unfunded ratio. I then show how the SS unfunded ratio is governed by x% funding targets and the gap between assumed and true returns. The SS degree of inequity is over 60% under an 80% funding target and over 50% with a one-point gap between assumed and true returns. (JEL H75)
