Many decisions involve trade-offs between present and future costs and benefits. We procrastinate difficult tasks, and we forgo larger rewards for smaller ones if we can get them sooner. Why do we change our minds about the value of upcoming events?

The behavioral discounting model presented in this technical note accounts for observed behaviors by incorporating patterns of overall high discounting, magnitude effects, and decreasing impatience.
