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...

Intertemporal correlation aversion is an intuitive concept indicating whether an individual prefers lotteries concerning consumption at different moments in time to be positively or negatively correlated. I show that the difference between the coefficient of relative risk aversion and the...

We explore how human capital investment of a child is affected by the number and the gender of his/her siblings. We test for two alternative explanations : competition for scarce resources versus direct interactions between siblings. We provide an empirical application using Brazilian data.

We show that taking into account the consequences of child labor on both childhood welfare and human capital investment, instead of focusing exclusively on the human capital dimension, brings new insights on the economic analysis of child labor. In particular, there are new sources of potential...

A number of empirical studies seem to reject the additive separability of preferences that is assumed in most theoretical models of the life cycle. We show that, when additive separability is abandoned and interactions between consumptions at different dates are taken into account, an...

This paper argues for an alternative methodology to estimate the value of risk to life. By relaxing the assumption of additive separability, we introduce risk aversion with respect to the length of life and show that the extended model better fits available data. This is crucial for the...
