Generic NDC : equilibrium, valuation and risk sharing with and without NDC bonds

The Non-financial (Notional) Defined Contribution (NDC) PAYGO pension scheme is a recent innovation and its generic dimensions have not previously been explored in a coherent context. This paper does this. It derives and analyzes the demographic, economic and distributional properties of NDC. The residual (systematic) longevity risk creates a special problem, solved with an NDC bond, the asset that closes the system financially, transferring residual risk to the government (taxpayers). This guarantees a fixed NDC contribution rate and, thus, intergenerational commitment, with transparent distributional policy pursued through targeted transfers from general tax revenues and taxation of overall personal income. -- Pensions ; NDC ; Notional Defined Contribution ; Non-financial Defined Contribution ; NDC Bond ; Risk sharing ; Pension Policy ; Pay-as-you-go ; PAYG
