The Discounted Utility Model The expected utility (EU) and marked down utility (DU) models give simple access to the interconnected areas of time and instability. Parallel in structure, both models view chiefs as selecting between choices taking into account a weighted entirety of utilities, with the weights being either probabilities (for EU) or markdown elements in view of time deferrals (for DU). EU and DU have been connected to such various points as work supply, sparing conduct, wrongdoing, and fruitfulness, and keep on being comprehensively used as both engaging and standardizing models of decision in spite of developing feedback of their presumptions and suggestions and an assault of option details.…show more content…
The psychological foundation was given by John Rae in 1834. He identified two inhibiting factors they are:  the uncertainty of human life  the urge for instant gratification exacerbated by the prospect of immediate consumption From Rae’s work there were two different approaches developed by William Jevons and Herbert Jevons. Both approaches dealing with the importance of current feelings, but it also explained clearly about the differences in time preferences. Another imperative work done on intertemporal utility is by Bohm- Bawerk and Pigou. According to them people generally underestimate future wants in comparison of present wants due to the time preference factors.

Consumption Independence: The main assumption of discounted utility model is that a person’s welfare in any time period is not depends upon his consumption activity in any other period. In broader sense the consumption independence says that the preference towards one thing is not depends up its consumption in previous time or the expectation of future consumption of that good.
