Short-run and long-run effects

Explanation or usage

An immediate benefit can come with later costs, while an immediate cost can support later benefits. Analysis should specify the period, affected people, and assumptions. A longer horizon does not automatically reverse a conclusion; it expands what must be checked.

Common misunderstandings

The immediate effect determines every later effect.
