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...

The aim of this contribution is to study the sustainability of a pay-as-you-go pension fund, through the analysis of demographic risk affecting these types of pension funds. A model for the evolution of the fund is presented considering the stochastic variables global asset return and new...

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...

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...

A model is presented that explains the mix between funded and unfunded pension systems. It turns out that total pension and the relative shares of the two systems may be explained and are determined by the population growth rate, technological growth, the time-preference discount rate, the...

This study provides a comprehensive analysis of the generational wealth transfer within Sweden's public pay-as-you-go pension system introduced in 1960. Using extensive administrative registers, the paper quantifies the contributions made and benefits received by each birth cohort. The findings...

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...

The Croatian system of old-age provision comprises a traditional public pay-as-you-go scheme and a mandatory funded scheme ("second pillar") that will provide increasing amounts of supplementary pensions to those entering retirement in the future. Due to the continuing economic crisis, the...
