Beggar Thy Thrifty Neighbour: The International Spillover Effects of Pensions Under Population Ageing

This paper explores the international spillover effects of ageing through capital markets when countries have different pension systems.We use a two-country twoperiod 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 PAYG system.The short-run spillovers, however, are opposite to the spillovers in the long run.
