Social Security programmes around the world link public pensions to retirement: people do not lose their pensions if they make a million dollars a year in the stock market, but they do confront marginal tax rates of up to 100% if they choose to work. After arguing that most existing theories...

The paper surveys and extends recent results on the effect of changes in government fiscal and financial policy, and in private savings behaviour, on economic growth. Private saving behaviour is represented by an overlapping generations (OLG) model. The supply side of the model permits...

This paper uses comparative statistics in a simple three-period overlapping generations model to show that any pay-as-you-go mechanism for public retirement pensions, when adopted in a dualistic economic system, penalises the most dynamic demographic groups, i.e., the <MI>developing<D> rather than the...</d></mi>

The European ageing process will lead to a dramatic rise in dependency ratios over the next decades. At the same time labour mobility will increase as a result of greater European economic integration. We analyse the implications of migration and ageing for European social security systems. With...

The present Paper studies the retirement incentives for elderly people in Belgium. We model the incentive structure built into the various public early retirement and retirement systems. First, we compute indicators of benefit entitlement such as the social security wealth. Then, we use three...

Is there an economic rationale for pronatalist policies? In this paper we propose and analyze a particular market failure that may lead to inefficiently low equilibrium fertility and therefore to a need for government intervention. The friction we investigate is related to the ownership of...

Generous early retirement provisions account for a large proportion of the drop in the labour force participation of elderly workers. The aim of this paper is to provide a political-economic explanation of the wide spread adoption of early retirement. We suggest that the political support for...

In this paper we re-examine poverty among working class households in inter-war London using the newly computerized records from the New Survey of London Life and Labour (NSLLL), a survey of living standards in London undertaken in 1929–31. First, we examine how the use of different poverty...

In many countries social security is a large fraction of the government budget. Why should this be so, given that at any moment in time the number of recipients of social security benefits is smaller than the number of contributors? More generally, what determines the size of social security? To...

Why does the largest US welfare programme select its recipients by their age, rather than by their earnings or wealth? In a dynamic efficient overlapping generation economy with earnings heterogeneity, we analyze a welfare system composed of a within-cohort redistribution scheme and an unfunded...
