Hyperbolic Discounting

What is it?

Hyperbolic discounting is a time-inconsistent preference pattern where we disproportionately value immediate rewards over future ones. Standard economic models assume exponential discounting, where value decreases steadily with delay; hyperbolic discounting instead creates a sharp drop in value for anything not immediate. Many people prefer $100 today over $110 tomorrow, yet choose $110 in 31 days over $100 in 30 days, even though both choices involve the same one-day wait. This creates preference reversals: we make commitments to our future selves that our present selves then break when the time comes. It helps explain procrastination (immediate comfort beats future completion), undersaving (present consumption beats future security), addictive behavior (immediate pleasure beats long-term health) and impulse buying (immediate satisfaction beats financial goals). Some brain-imaging studies suggest we think about our future selves somewhat as we think about other people. Strategies to combat hyperbolic discounting include commitment devices (binding future choices), automation (removing moment-of-decision temptation), mental time travel (vividly imagining future states), and reducing the friction of future-oriented choices while increasing the friction of short-term temptations.
