The two basic systems according to which pay-as-you-go-financed public-pension systems can be organized are the (Anglo-Saxon) Beveridge system and the (continental) Bismarck system. An ideal Beveridge system provides flat-rate benefits, whereas an ideal Bismarck system provides earnings-related benefits. This paper analyzes the circumstances under which a Beveridge system can be sustainable in systems competition with a Bismarck system. The analysis reveals a much more complicated redistributive structure of the pension systems than only between high and low incomes. As a consequence, the sustainability depends on growth rates, and equilibria can exist where, contrary to the first intuition, even poor individuals prefer a Bismarck and rich individuals prefer a Beveridge system.
