Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer, Alexander Holmes, Barbara Illowsky, Susan Dean. Intertemporal choice is the process by which people make decisions about what and how much to do at various points in time, when choices at one time influence the possibilities available at other points in time. there's a tradeoff for benefit now or larger benefit in future, Temporal Discounting Study (Brain activation, 3 different graphs), - you are put in fMRI and while scanning, you're looking at monitor and making decisions, desirability of that option independent of time. what does this area do? This paper provides a set of replications showing the effects of scarcity on cognition and behaviour. Article The tendency to make unhealthy choices is hypothesized to be related to an individual's temporal discount rate, the theoretical rate at which they devalue delayed rewards. Sylvia Walters never planned to be in the food-service business. Discount rates comprise of two sub-rates - the falling relative price of goods due to technological change and economic growth, and a temporal discounting rate, also called the time preference. They are discounted in accordance with their delay. K is unrelated in every way and does not need to be the same.

Self control: the individual will choose a larger delayed reward over a smaller immediate reward. What are the limitations and benefits of using free parameters? Pathological gambling has been conceptualized as a series of impulsive choices whereby the gambler selects the smaller, less probable immediate opportunity to obtain money over the larger, more probable delayed opportunity to save money. Time preferences are captured mathematically in the discount function.The higher the time preference, the higher the discount placed on returns . We tested the hypothesis that cognitive decline is . Not the too general category of "visceral" anticipatory emotions (Loewenstein and Lerner), but more specifically emotions related to agency ("driving anticipatory emotions"). what does hyperbolic discounting teaches us about our choices? depend on the delay time period, people usually pick the small amount and small delay.
