%0 Report %A Manzini, Paola %A Mariotti, Marco %T A Vague Theory of Choice over Time %D 2004 %8 2004 Jul %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 1228 %U https://www.iza.org/index.php/publications/dp1228 %X We propose a novel approach to modelling time preferences, based on a cognitive shortcoming of human decision makers: the perception of future events becomes increasingly ‘blurred’ as the events are pushed further in time. We axiomatise a class of preference representations which can be specialised to rationalise ‘anomalies’ such as preference reversals and cyclical preferences. We also present an application to a form of time inconsistency which we dub ‘the now or never fallacy’. %K hyperbolic discounting %K time preferences %K intransitive preferences %K preference reversal %K cycles
