Implementing a fairness component into a standard overlapping-generations model and allowing young individuals to vote on their own pension payments, we show that they adapt the pay-as-you-go pension scheme to future demographic changes. In particular, we explain why young generations cut their...

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...

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...

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...

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...

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...

Incomplete markets in overlapping generations leave room for Pareto improvement. We analyze a model with two goods and idiosyncratic shocks. We compare market equilibrium with the constrained efficient equilibrium allocation and demonstrate that, when shocks are symmetric and do not affect all...

In the presence of endogenous growth intergenerational transfer from the young to the old reduce per capita income growth and harm future generations. On the other hand, competitive equilibria are inefficient if externalities sustain long-run growth. This paper shows that if individuals retire...
