In this paper, we investigate the possibility of representing ethical intergenerational preferences using more than one utility function. It is shown that the impossibility of representing intergenerational preferences equitably persists in the multiutility frame work with some reasonable...

In this paper we show that if a strongly monotone inter-temporal order exhibits no preference towards the advancement of timing of future utility on any infinite utility stream, then the existence of such an order must involve some non-constructive device

We study order theoretic and topological implications for impatience of weakly Paretian, representable orders on infinite utility streams. As a departure from the traditional literature, we do not make any continuity assumptions in proving the existence of impatient points. Impatience is robust...
