This paper uses stochastic simulations on calibrated models to assess the optimal degree of reliance on fun ded pensions and on a particular type of unfunded (PAYG) pension. Surprisingly little is known about the optimal split between funded and unfunded systems when there are sources of...

We analyze the rationale for the pay-as-you-go (paygo) pension system existence on diversi fication grounds. A continuous-time portfolio choice setting is built, basing on Merton (1971)´s analysis, where a reasonable balance between the taking account of the economic and fi nancial facets of...

The creeping stock market collapse eroded the wealth of funded pension systems. This led to political tensions between generations due to the fuzzy definition of property rights on the pension funds wealth. We argue that this problem can best be resolved by the introduction of generational...

Does the Endowment Model still work? Judging by large endowments' steady outperformance of a 70% global stock/30% US bond index, THE ANSWER IS YES. Versus a 60% US stock/40% US bond index, the answer is not as clear cut.Even so, the Endowment Model still adds value for a long-term portfolio that...

Pensions may be provided for in a modern society by several methods, viz., voluntary individual savings, mandatory fully funded occupational pension systems, and mandatory social security financed by pay-as-you-go. The specific mixture of the three systems we will call the pension composition....

The change in economic and sociodemographic reality, characterized by a continuous increase in longevity, the consequences of the economic crisis, and the lack of adequate adjustments of social security retirement pension systems everywhere, entails risks for workers and the social security...

We explore the feasibility of a funded pension system with intergenerational risk sharing when participation in the system is voluntary. Typically, the willingness of the young to participate depends on their belief about the future young's willingness to do so. We characterise equilibria with...

Public pension systems are usually pay-as-you-go financed, that is, current contributions cover the pension expenditures. However, some countries combine funding and pay-as-you-go within the first pillar. This article studies a mixed system where a part of the individual's contribution accrues...
