Do All Constructive Strongly Monotone Inter-Temporal Orders Exhibit Impatience?, Kuntal Banerjee, Ram Dubey
Do All Constructive Strongly Monotone Inter-Temporal Orders Exhibit Impatience?, Kuntal Banerjee, Ram Dubey
Department of Economics Faculty Scholarship and Creative Works
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.
Impatience Implication Of Weakly Paretian Orders: Existence And Genericity, Kuntal Banerjee, Ram Dubey
Impatience Implication Of Weakly Paretian Orders: Existence And Genericity, Kuntal Banerjee, Ram Dubey
Department of Economics Faculty Scholarship and Creative Works
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 in the sense that there are uncountably many impatient points. A general statement about genericity of impatience cannot be made for representable, weakly Paretian orders. This is shown by means of an example. If we assume a stronger sensitivity condition, then genericity obtains.
