"This paper attempts to integrate the concern for human development in the present with that in the future. In arguing for sustainable human development, it appeals to the notion of ethical universalism''Ðan elementary demand for impartiality of claimsÐapplied within and between generations. Economic sustainability is often seen as a matter of intergenerational equity, but the speci®cation of what is to be sustained is not always straightforward. The addendum explores the relationship between distributional equity, sustainable development, optimal growth, and pure time preference."
