Where:
Utility = preference for a course of action (the higher the utility, the greater the preference)
E=expectancy
V=value
G=sensitivity to delay
D=delay (how long the wait for payoff)
"On the top of the equation, the numerator, we have two variables: Expectancy (E) and Value (V). Expectancy refers to the odds or chance of an outcome occurring while Value refers to how rewarding that outcome is. Naturally, we would like to choose pursuits that give us a good chance of having a pleasing outcome. On the bottom of the equation, the denominator, we also have two variables. G refers to the subject’s sensitivity to delay. The larger G is, the greater is the sensitivity. Finally, D represents Delay, which indicates how long, on average, one must wait to receive the payout. Since delay is in the denominator of the equation, the longer the delay, the less valued the course of action is perceived."
