This article is about a concept of economic theory. For discussion of the term “margin” as used in the jargon of bourses, see Margin (finance).

In economics, a margin is a set of constraints conceptualised as a border.[1] A marginal change is the change associated with a relaxation or tightening of constraints — either change of the constraints, or a change in response to this change of the constraints.[1]

Extensive and intensive margins[edit]

Margins are sometimes conceptualized[by whom?] as extensive or intensive:[citation needed]

  • An extensive margin corresponds to the number of usable inputs that are in some sense employed. For example, hiring an additional worker would increase an extensive margin.
  • An intensive margin corresponds to the amount of use extracted within a given extensive margin. For example, reducing required production from a given set of workers would decrease the intensive margin.
