Many Western countries with an aging population consider reforms of their pay-as-you-go pension systems. In Sweden a new pension system has already been decided and implemented. This paper gives a brief background to the Swedish reforms in the 1990s and explains the structure of the new system.

In earlier literature, the suggested Pareto improvements in pay-as-you-go (PAYG) systems have relied on the presence of externalities or the possibility of intragenerational redistribution. We show that neither assumption is necessary in an economy with intergenerational trade in a fixed factor...

Using a heterogeneous-agent, life-cycle model of Social Security claiming, labor supply and saving, we consider the implications of lifespan inequality for Social Security reform.

Notional defined contribution pension schemes (NDCs) aim at reproducing the logic of a financial defined contribution plan under a pay-as-you-go framework. Of particular interest is how the accumulated capital of a deceased person is used, when the death occurs prior to retirement. While in most...
