Marginalism — quantity v. rate
First, let's note that a rate is a ratio of one quantity to another. Now, while marginalism is often concerned with rates; it isn't ''always.

For example, a marginal use is the use associated with an increase or decrease of the quantity of some good or service. The use itself may not be quantifiable, hence, there may not be any ratio.

(In fact, the neoclassical assumption that utility is at least weakly quantified is not shared across all schools of marginalism; there isn't necessarily any rate associated with marginal utility, the epitomal notion of marginalistm.) —SlamDiego&#8592;T 18:43, 17 August 2008 (UTC)
