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...
