Continuous longevity improvements and population ageing have led countries to modify national public pension schemes by increasing the standard and early retirement ages in a discretionary, scheduled, or automatic way, and by making it harder for people to retire prematurely. To this end,...

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 discusses the efficiency of a pay-as-you-go pension reform by introducing a child benefit in an endogenous fertility setting. In the model of a small open economy, higher fertility is associated with a reduction of lifetime labor supply. The optimum share of fertility-related pensions...

One of the main reasons to include pay-as-you-go (PAYG) schemes in multi-pillared pension systems is that they may entail beneficial risk-sharing and diversification features However, depending on the pension formula these features vary significantly for different types of PAYG schemes. We...

In this paper we address the question whether in case of population ageing a transition from an unfunded to a more funded pension scheme is politically feasible in a representative democracy. We consider two parties: a right-wing party which is willing to trade off intragenerational equity...

Using an OLG model with skill uncertainty and private savings, we investigate whether an optimally designed set of public pension transfers can usefully supplement a nonlinear labor income tax as a welfare-enhancing policy instrument. We consider a Mirrleesian setting where agents' skills are...

Pensions may be provided for in a modern society by a mix of several methods, namely by voluntary individual savings, mandatory fully-funded occupational pension systems, mandatory social security financed by pay-as-you-go, and old-fashioned hoarding in cash. Here, we call the specific mixture...

We study the impact of a fully-funded social security system in an economy with heterogeneous consumers. The unobservability of individual health conditions leads to adverse selection in the private annuity market. Introducing social security - which is immune to adverse selection - affects...

In this paper, we consider how the hours of work and retirement age ought to respond to a change in the uncertainty of the length of life. In a first best framework, where a benevolent government exercises perfect control over the individuals' labor supply and retirement-decisions, the results...

Within a politico-economic model we first establish three hypotheses: (i) Retirees generally prefer a higher retirement age than workers, whereby just retired individuals prefer the highest retirement age, (ii) in equilibrium the level of the legal retirement age is increasing in longevity and...
