Population ageing increases fiscal pressure by increasing the aged to working-age ratio, which simultaneously reduces the growth in government revenue and increases government social outlays. This study uses sensitivity analysis on a simulation model to evaluate proposed tax and economic growth policies to meet the population ageing induced fiscal pressure and to clarify inconsistencies between these policy proposals.
