Pensions at a Glance, however, shows pension benefits as a share of individual lifetime average earnings (revalued in line with economy-wide earnings growth). In the standard assumption of the OECD pension models, a person’s income grows in line with economy-wide average earnings, which means that using the last or average lifetime income will yield the same result. A simple starting point is to say that standards of living in retirement should be the same as those enjoyed during working life.
