No it's not. The cost of providing a pension is comparable to establishing a sinking fund, not to purchasing an annuity.
I respectfully disagree.
The cost of purchasing an annuity that provides a comparable benefit to an individual State pension is a perfectly valid, if imperfect, way of estimating the actuarial value of that pension. I believe I have already explained why I consider your "sinking fund" approach to be inappropriate.
Also, on what planet are you living?
I'm afraid I don't have an answer to that knockout argument!
As you know, the Department of Public Expenditure and Reform carried out an actuarial valuation of the State's public service pension liabilities as at December 2012.
The key result was that the total accrued liability in respect of public service pensions was estimated at €98bn. This compares with the previous estimate of €116bn for 2009. Therefore, over the three years from 2009 to 2012 the liability had fallen by €18bn or by 16% and the main reasons for the reduction were the pay and pension cuts since 2009 and the freeze in pay and pension rates that are currently under negotiation.
The Department itself has estimated that the accrued liability would fall by a further €16bn if future pension increases were linked to inflation, rather than the salary increases of serving staff members.
Whatever way you look at it, the accrued (and obviously unfunded) public sector pension liability is a big number and the question remains as to how it will be discharged when the ratio of retirees to workers is projected to deteriorate from 1:5 to 1:2 by 2050.
Put bluntly, where's the money going to come from in the future?
