===Marginalism===
Marginalism is an economic theory that states that the value of a determined good is the value of its subjectively least valuable use. Thus, the marginal value (of the next unit of the good in question to be acquired) decreases as the most valuable uses for the good are satisfied, or the opposite happens as one's stock of a good decreases, as one forgoes the least valuable uses for a good firstly upon losing a certain amount of such good.<br>Consequently, in all economic designs, the values, costs, revenues, productivity, and so on are determined by the significance of the last unit added to or subtracted from the total stock.
