Decision at the margin

Decision at the margin refers to the process of evaluating the additional benefits and costs associated with a particular choice or action. It involves comparing the incremental advantages of a decision to its incremental disadvantages to determine whether the action should be taken. This principle is fundamental in economics, as it helps individuals and businesses make informed choices that maximize utility or profit. Essentially, it emphasizes that decisions should be made based on the effects of small changes rather than on total costs or benefits.
