The Rate of Return of Pay-As-You-Go Pension Systems: A More Exact Consumption-Loan Model of Interest

Abstract

The article presents a method for calculating the cross-section internal rate of return on contributions to pension systems financed according to the pay-as-you-go principle. The method entails a procedure for valuing the contribution flow of pay-as-you-go financing, and identifies the complete set of factors that determine the cross-section internal rate of return. The procedure makes it possible to apply the algorithm of double-entry bookkeeping in analyzing and presenting the financial position and development of pay-as-you-go pension systems.Social Security, Public Pensions, Internal rate of return, Accounting
