When markets are incomplete, social security can partially insure against idiosyncratic and aggregate risks. We incorporate both risks into an analytically tractable model with two overlapping generations and demonstrate that they interact over the life-cycle. The interactions appear even though...

This paper studies the impact of an unfunded social security system on the distribution of bequests in a framework where savings are due both by life cycle and by random altruistic motivations. We show that the impact of social security on the distribution of bequests depends crucially on the...

Social security provides retirement benefits to the old at the expense of the working young, while environmental investment benefits the future of the young at the expense of the old. This paper presents a model incorporating this inter-generational conflict on public spending, and considers the...

This paper analyzes a social security policy with public debt in an overlapping generations growth model. In particular, the paper considers a situation in which population aging causes a heavy burden of social security payments where public debt is issued by the government to finance the...

This paper studies the connection between social security policy and international factor movements within a two- country overlapping-generations model with production. Incentives for factor movements emerge because one country relies on private savings while the other country operates a social...

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 seeks to estimate the distributive impact of the taxes and other fiscal contributions that finance social security in Brazil. Making a certain number of strong hypotheses relative to the fiscal incidence of social security financing, we compute a measure of incidence that aggregates...

This paper investigates the fiscal pressure from demographic change in relation to the labour marketspace for fifty countries that cover 75% of the world population. The pressure-to-space indicator ranks Poland, Turkey and Greece high. Apart from Turkey and India, developing countries rank low...

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...
