On sustainable pay as you go systems
Demange, Gabrielle - HAL - 2005
An unfunded Social Security system faces the major risk, sometimes referred to as "political risk", that future … generations modify or even suppress the contributions. In order to account properly for this risk, the paper considers a political … the economy. The impact of various factors -intra-generational redistribution, risk aversion, financial markets …

External Constraints and Endogenous Growth: Why Didn't Some Countries Benefit from Capital Flows?
Gente, Karine; León-Ledesma, Miguel; Nourry, Carine - HAL - 2013
Empirical evidence on the growth benefits of capital inflows is mixed. The growth benefits accruing from capital inflows also appear to be larger for high savings countries. We explain this phenomenon using an OLG model of endogenous growth in open economies with borrowing constraints that can...

Fair Intergenerational Sharing of a Natural Resource
D'Albis, Hippolyte; Ambec, Stefan - HAL - 2010
In this article, overlapping generations are extracting a natural resource over an infinite future. We examine the fair allocation of resource and compensations among generations. Fairness is defined by core lower bounds and aspiration upper bounds. The core lower bounds require that every...

Vieillissement de la population en Italie et efficacité des réformes Amato et Dini : un modèle d'équilibre général à générations imbriquées
Magnani, Riccardo - HAL - 2006
L'objectif de ce papier est d'analyser les impacts du vieillissement de la population italienne sur le système économique et en particulier sur le système de retraite afin d'évaluer l'efficacité des réformes mises en place durant les années 90 (réforme Amato en 1992 et réforme Dini en...

Implementing steady state efficiency in overlapping generations economies with environmental externalities
Dao, Nguyen Thang; Davila, Julio - HAL - 2010
We consider in this paper overlapping generations economies with polution resulting from both consumption and production. The competitive equilibrium steady state is compared to the optimal steady state from the social planner's viewpoint. We show that any competitive equilibrium steady state...

A Note on Indeterminacy in Overlapping Generations Economies with Environment and Endogenous Labor Supply
Seegmuller, Thomas; Verchère, Alban - HAL - 2007
We consider an overlapping generations model with environment and an elastic labor supply. In this framework, consumers have to choose between consumption, environmental quality, and leisure. We show the existence of both deterministic cycles and indeterminacy. In contrast to previous results,...

Capital-labor Substitution and Endogenous Fluctuations: a Monopolistic Competition Approach with Variable Mark-up
Seegmuller, Thomas - HAL - 2009
In macroeconomics, economists introduce most frequently imperfect competition on product markets using the Dixit and Stiglitz (1977) monopolistic competition model. However, by assumption, this framework ignores one important feature of imperfect competition: strategic interactions between...

Can Heterogeneous Preferences Stabilize Endogenous Fluctuations?
Bosi, Stefano; Seegmuller, Thomas - HAL - 2008
While most of the literature concerned with indeterminacy and endogenous cycles is based on the restrictive assumption of a representative consumer,some recent contributions have investigated the role of heterogeneous agents in dynamics. This paper adds to this latter strand of the literature by...

Can heterogeneous preferences stabilize endogenous fluctuations ?
Bosi, Stefano; Seegmuller, Thomas - HAL - 2006
While most of the literature concerned with indeterminacy and endogenous cycles is based on the questionable assumption of a representative consumer, some recent works have investigated the role of heterogeneous agents on dynamics. This paper adds a contribution to the debate, highlighting the...
