An Integrated Notional Defined Contribution (NDC) Model with Retirement and Permanent Disability
2014
In this paper we develop a theoretical basis for integrating retirement and permanent disability using a generic NDC framework. The methodology used relies on a multistate overlapping generations model that includes the so-called survivor dividend. Currently this feature can only be found in the Swedish defined contribution (DC) scheme. The results achieved in the numerical example we present endorse the fact that the model works well. Special attention is given to the assumptions made about mortality rates for disabled people and disability incidence rates, which largely determine the contribution rate assigned to disability. The model could be of interest to policymakers because, after so…
Notes on Using the Hidden Asset or the Contribution Asset to Compile the Actuarial Balance for Pay-as-You-Go Pension Systems
2010
The aim of this paper is twofold: to determine the connection between the “contribution asset” and the “hidden asset” and to discover whether using either of them to compile the actuarial balance in Swedish-type pay-as-you-go pension systems will provide a reliable solvency indicator. We develop an overlapping generations model and apply it to the defined benefit pay-as-you-go system, although it would be just as valid for NDC systems. On the theoretical side the main conclusion is that, despite their very different natures, in a simplified scenario the contribution asset and the hidden asset could coincide if r - the real rate of interest - is equal to the growth in the wage bill. On the a…
Optimal savings and health spending over the life cycle
2010
This paper investigates the relationship between saving and health spending in a two-period overlapping generations economy. Individuals work in the first period of life and live in retirement in old age. Health spending is an activity that increases quality of life and longevity. Empirical evidence shows that both health spending and saving behave as luxury goods but their behaviour differs markedly according to the level of per capita GDP. The share of saving on GDP has a concave shape with respect to per capita GDP, whereas the share of health spending on GDP increases more than proportionally with respect to per capita GDP. The ratio of saving to spending is nonlinear with respect to in…
