We introduce and analyze a novel collective defined contribution plan (CDC) which guarantees upon retirement at least a target benefit as a lump sum. The guarantee is provided by the remaining working generations under a pre-determined linear intergenerational risk sharing (IRS) rule. Through a...

In a recent paper (2006), Pestieu et.al. showed that the optimal payroll tax rate for the PAYG pension in an open large economy should increase as number of countries increases. This rather counterintuitive result -increasing the factor mobility makes redistribution easier-depends on a crucial...

The paper analyses the impact of demographic developments on the German pension system until the year 2060. The projections are simulated for a range of assumptions on the latest demographic trends and on the labour market and comprise the latest pension legislation. As a central innovation we...

A general framework is analyzed which contains several special transfer (tax and pension) models. In our static two-overlapping-generation framework, every individual works in the first stage of the adult age, while is retired in the second. The government operates a balanced linear transfer...

This paper analyzes the effects of an unfunded pension system on economic growth using an extended overlapping generations model to include the informal sector. Emerging countries usually have a more significant informal sector than advanced ones. The findings based on the Thai economy data...

In this paper we study the implications of population ageing in an economy with a sizeable non-traded goods sector. To this effect a highly stylized micro-founded macro model is constructed in which the age structure of the population plays a non-trivial role. The model distinguishes separate...

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...

This paper explores the introduction of collective risk-sharing elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset contingent risk-sharing arrangements. All arrangements raise aggregate welfare, as measured by equivalent variations. While...
