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...

This paper provides a quantitative analysis of hypothetical replacements of existing tax arrangements applied to superannuation (Australia's term for private pensions) with traditional EET and TEE regimes. These taxation regimes exempt pension fund earnings from any taxation and tax either...

We study transitions from EET tax regime to TEE regime in a defined-benefit pension scheme with a numerical overlapping generations model, using stochastic mortality projections as inputs. In a traditional pension scheme with no automatic longevity rules, such as a link between life expectancy...

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...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

This paper considers the quantitative role of growth in the size of the social security program in contributing to the collapse of personal saving in the U.S. over the last few decades. Using a calibrated, general equilibrium life-cycle model this paper shows that social security may not be to...

The present paper studies the growth and efficiency consequences of pension funding with individual retirement accounts in a general equilibrium overlapping generations model with idiosyncratic lifespan and labor income uncertainty. We distinguish between economies with rational and hyperbolic...

A pay-as-you-go (paygo) pension program may provide intergenerational pooling of risks to individuals' labor and capital income over the life cycle. By means of a model that provides illuminating closed form solutions, we demonstrate that the magnitude of the optimal paygo program and the nature...

Aging creates financial troubles for PAYG pension systems, since the share of retirees to workers increases. An often advocated policy response is to increase retirement age. Ironically, however, the political support for this policy may actually be hindered by population aging. Using Swiss...

This paper sheds light on the role of public institutions as a way to reduce tax evasion through a close link between payroll taxation and pension benefits. We use a political economy model in which agents have the possibility to hide part of their earnings in order to avoid taxation. Taxation...
