Existing literature continues to be unable to offer a convincing explanation for the volatility of the stochastic discount factor in real world data. Our work provides such an explanation. We do not rely on frictions, market incompleteness or transactions costs of any kind. Instead, we modify a...

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...

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...

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...

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...

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,...

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...

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...

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...

Introduced by Samuelson (1975), the Serendipity Theorem states that the competitive economy will converge towards the optimum steady-state provided the optimum population growth rate is imposed. This paper aims at exploring whether the Serendipity Theorem still holds in an economy with risky...
