We investigate intergenerational risk sharing in two-pillar pension systems with a pay-as-you-go pillar and a funded pillar. We consider shocks in productivity, depreciation of capital and inflation. The funded pension pillar can be either defined contribution or defined benefit, with benefits...

In the coming decades, the share of people in working age will fall significantly in most developed countries. According to optimal taxation theory, public debts should be reduced before the baby-boom generation retires. I find that if debts are instead maintained at the current levels, welfare...

Starting from a simple, descriptive model of individual income, an explicit link between the age composition of a population and the personal distribution of incomes is established. Demographic effects on income inequality are derived. Next, a pay-as-you-go financed state pension system is...

The paper reviews recent research on the impact of an aging population on the distribution of income. After briefly discussing the demographic conditions responsible for population aging, a short account is given of demographic trends in the industrialized world. In order to disentangle the many...

In 1998, the Swiss voters approved of an increase in female retirement age from 62 to 64. The referendum, being on a single issue only, offers a unique opportunity to explore the political feasibility of pension reforms and to apply theoretical models of life-cycle decision making. Estimates...

Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

Intergenerational inequality and old-age poverty are salient issues in contemporary China. China's aging population threatens the fiscal sustainability of its pension system, a key vehicle for intergenerational redistribution. We analyze the positive and normative effects of alternative pension...

The pay-as-you-go social security system, burdened by dwindling labour force, can benefit from immigrants, with birth rates that exceed the native-born birth rates. Thus, the social security system effectively provides an incentive to liberalize migration policy through a political-economy...

A shift in taxes or in government spending (a ”fiscal shock”) at some point in time puts a constraint on the path of taxes and spending in the future, since the government intertemporal budget constraint will eventually have to be met. This simple fact is surprisingly overlooked in analyses...
