We study the role of alternative intertemporal preference representations in a model of economic growth, stock pollutant and endogenous risk of catastrophic collapse. We contrast the traditional "discounted utility" model, which assumes risk neutrality with respect to intertemporal utility, with...

This paper introduces a life-cycle model where impatience, instead of being driven by an exogenous discount function, results from the combination of risk aversion and mortality risks. Opting for such a formulation provides novel views on the impact of longevity extension on welfare, saving...

We consider a formal approach to comparative risk aversion and applies it to intertemporal choice models. This allows us to ask whether standard classes of utility functions, such as those inspired by Kihlstrom and Mirman (1974), Selden (1978), Epstein and Zin (1989) and Quiggin (1982) are...

[eng] The Welfare State is generally thought to transfer resources from young and future generations to old ones. This opinion, however, is based on a narrow view of the transfer system that focuses on pensions and elderly-care programs. Our paper shows that taking downward educational transfers...

This paper studies the problem of redistribution between individuals having different mortality rates. We use a continuous time model in which there are two types of individuals characterized by different survival probability paths. Individual preferences are represented by a generalized...
