This paper presents long term projections of the German pension system that are based on a general equilibrium model with overlapping generations (OLG). This framework takes into account the two way feedback of both micro and macroeconomic relationships, meaning that households, for example,...

The paper investigates the impacts of demographic change on the financial sustainability of a pay-as-you-go social security system in an economy with unemployment caused by trade unions. Using a simple two-period overlapping generations approach, it can be shown that the trade union behavior...

The paper shows the effect of demographic change on per capita burden of financing a PAYG social security system in the standard OLG model with frictional labor markets. Rising longevity and decreasing fertility both induce a rise in the employment level via increased capital accumulation and...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...

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...

This paper explores the introduction of collective risk-reallocation elements in defined contribution pension contracts. We consider status-contingent, age-contingent and asset-contingent arrangements to reallocate risk among participants. Eliminating asset market risk for the retired raises...

This paper analyses whether the severe demographic change in Germany causes its high current account surpluses. An ageing population both increases the supply and lowers demand of capital in an economy. Due to a longer life span individuals save more. Fewer workers reduce the optimal capital...

Demographic change inevitably shifts the balance between contributors and recipients in the pension system. Moreover, in the German pension system benefit levels are closely linked to the current state of economic prosperity. Therefore, in the coming decades stabilisation of old-age security...
