Alternative Retirement Income Arrangements and Lifetime Income Inequality: Lessons From Australia

Abstract

This paper examines the implications for lifetime income equality of alternative retirement income arrangements, using the Australian scheme as a benchmark. In Australia, the pay-as-you go financed age pension is means-tested and thereby provides a contrast with those countries where part or all of a basic pension is paid to all aged persons. Many governments are considering an increase in the level of means-testing. The results show that the introduction of a universal pension coupled with significant changes and simplifications to the structure of taxation and superannuation have little effect on the redistributive impact of the tax structure in a life cycle framework. The presence of means-testing appears to have no significant effect on life-time inequality. The results suggest that it is possible to eliminate complexities from the system providing retirement benefits without having any deleterious effect on equity.
