This paper proposes and analyzes a model of a European economy with three overlapping generations, redistributive social security, and public universities without tuition. Individuals differ ex ante. The effect of wage tax rate on occupational choice and the voting equilibrium of wage tax rate...

We propose a unified framework to measure the effects of different reforms of the pension system on retirement ages and macroeconomic indicators in the face of demographic change. A rich overlapping generations (OLG) model is built and endogenous retirement decisions are explicitly modeled...

Namibia is an upper middle-income country with one of the most comprehensive social protection systems in Africa. It provides cash transfers and complementary social assistance to a range of vulnerable groups including children, the elderly and people with disabilities, at a cost equivalent to...

In this paper we analyze the recent performance, perspectives and some policy options for two public social security programs in Uruguay: pensions and unemployment insurance.We review the impact of these programs on public expenditure, including recent and expected future trends, and on income...

The partial privatization of the US Social Security system was clearly the top economic policy priority for the new Bush administration. While many famous economists, publicists and politicians support, others reject the partial privatization of the Social Security system. The international...

Demographic projections forecast a doubling of the dependency ratio until 2050 as well as an increase of 10% in population due to longer life expectancy in Switzerland. To quantify the effects on social security and public finances, we use a computational overlapping generations model with five...

We analyze the effect of the projected demographic transition on the political support for social security, and equilibrium outcomes. Embedding a probabilistic-voting setup of electoral competition in the Diamond (1965) OLG model, we find that intergenerational transfers arise in the absence of...

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 examine the impact of a stylized pay-as-you-go (PAYGO) Social Security program in an economy of overlapping generations with equilibrium growth. We adopt realistic mortality and other demographic assumptions and allow for the presence or absence of full life annuities. In all cases we find...

This article gives exact general conditions for the existence of an interior optimum growth rate for population in the neoclassical two-generations-overlapping model. In an economy where high (low) growth rates of population lead to a growth path which is efficient (inefficient) there always...
