In economics, the study of the effect of
increasing a factor by one more unit (known
as the marginal unit). For example, if a
firm's production is increased by one unit,
its costs will increase also; the increase in
costs is called the marginal cost of
production. Marginal theory is a central tool
of microeconomics.
