Health status, life expectancy and early claiming of pension

"Prior to 2011, individual life expectancy played no role in the Norwegian old-age pension system. However, after the 2011 reform, life expectancy became a central factor for early pension take-up.  Individuals who expect to live longer than the average for their birth cohort can maximize their pension wealth by deferring pension claiming, while those with a shorter life expectancy should draw their pension as early as possible. This raises concerns that adverse selection may pose a risk to the sustainability of the new pension system."
