About Delay Aversion

In this paper we study the behaviour of decision makers who show, quoting Irving Fisher, preferences for advancing the timing of future satisfaction. We gave two definitions that could represent this kind of attitude and we studied their implications in three popular models used in decision theory, proposing alternatives to the usual concept of discounting. We found interesting links with the theory that studies the impossibility of aggregating infinite streams of income (or utility) keeping both strong monotonicity and equality among all generations, and with the notion of domination of a streams of income over another one at all interest rates.
