ABSTRACT
This chapter extends the calculation of internal rates of return to sub-populations divided by characteristics other than gender. The relevance is that, given the Canada Pension Plan (CPP) goals, cohort-specific rates of return for particular sub-populations should be, or can be expected to be, higher or lower than the corresponding value for the full population cohort. The chapter examines five groups of particular policy interest. It include– persons with low lifetime earnings, ever-married persons, immigrants, persons taking up retirement benefits prior to the "normal" retirement age of 65, and persons receiving a CPP Disability benefit. Other sub-populations might also be of interest, ever-divorced, or high-education, or those using the provisions to drop child-rearing years out of the calculation of average earnings, or the complements of the groups. In a second extension of the earlier work, also presents preliminary results for real after-tax internal rates of return.
