This paper explores the international spillover effects of ageing through capital markets when countries have different pension systems. We use a two-country two-period overlapping-generations model, where the two countries only differ in their pension schemes. Two forms of population ageing are considered, namely, an increase in longevity and a fall in fertility. It is shown that, in the long run, a country using a funded pension system experiences negative spillovers from the fact that the other country uses a pay-as-you-go system. The short-run spillovers, however, are opposite to the spillovers in the long run.
