Valuing Pensions (Annuities) with Different Types of Inflation Protection in Total Compensation Comparisons

Pensions provided in the public sector are often indexed, while pensions in the private sector typically are not. To conduct the total compensation comparisons that ostensibly guide government pay policy, one must value annuities which differ in their degree of inflation protection. This paper conducts this exercise from the viewpoint of modem finance theory, and contrasts the results with those of a representative government, the Government of Canada. The results suggest that governments may typically understate the value of indexed pensions and overstate the value of pensions which receive incomplete inflation protection. A contributing factor is the apparent belief that standardizing actuarial assumptions is sufficient to ensure comparability, in spite of the fact that risk is ignored and that interest rate and inflation assumptions are typically not those of the market.
