Social Security Systems, Human Capital, And Growth In A Small Open Economy

The authors consider a small open economy in which the level of public education funding is determined by popular vote. They show that growth can be enhanced by the introduction of pay-as-you-go pensions even if the growth rate of aggregate wages falls short of the interest rate. The reason is that the PAYG system allows future retirees to partially internalize positive externalities of public education due to the positive effect of higher future labor productivity on their pension benefits. The majority support for education funding will be especially strong when the PAYG benefit formula is flat, i.e. progressively redistributive.
