Two recent articles (Córdoba and Ripoll, 2017; Hugonnier, Pelgrin, and St-Amour, 2013) have proposed a recursive formulation of utility functions combining a positive value of life, preference homotheticity, and a constant elasticity of substitution. However, when the elasticity of substitution is...

An axiomatic construction for lifecycle preferences accounting for the finiteness and the randomness of life duration is provided. We emphasize the role of intertemporal correlation aversion and explain why multiplicative preferences provide an interesting alternative to additive preferences,...

We develop a simple theoretical framework that identifies time preferences without relying on a particular utility function. Our empirical strategy requires observations about intertemporal consumption allocation decisions made under varying relative prices, and seeks to approximate the marginal...

This papers provides an explanation for time preference: we show that in the case of uncertain lifetime, future consumption should be weighted not only according to survival probability, but also according to a discount factor due to risk aversion with respect to the length of life. When...

I compare two different ways of integrating mortality into life-cycle models: the standard additive model with time preferences, on the one hand, and a formulation that rules out the existence of time preference, but allows for risk aversion with respect to the length of life, on the other hand....

This paper makes explicit the links between preferences over lotteries on length of life and intertemporal choice. I show that the approach used by traditional life cycle models to account for uncertain survival corresponds to a strong assumption of risk neutrality with respect to the length of...

This paper develops an axiomatic construction of preferences that allows to compare lotteries involving lives of different lengths. Our axioms which basically formalize two assumptions - individuals are rational and have stationary preferences - leads to a class of utility functions that is much...
