 abstract = {Research on the psychology of intertemporal choice typically employs a choice between a small immediate outcome and a larger delayed outcome. The decision maker makes a series of choices or gives a judgment to indicate how much larger the delayed outcome would need to be to make it just as attractive as the immediate outcome. This indifference point can be used to compute the temporal discount rate, or the percentage increase in magnitude that is needed to offset a given time delay. For example, if someone said that $100 to be received now was just as attractive as $110 to},
