TOTAL PRODUCT AND MARGINAL PRODUCT: A mathematical connection between marginal product and total product stating that marginal product IS the slope of the total product curve. If the total product curve has a positive slope (that is, is upward sloping), then marginal product is positive. If the total product curve has a negative slope (downward sloping), then marginal product is negative. If the total product curve has a zero slope (horizontal), then marginal product is zero. Moreover, if the total product curve has a positive and increasingly steeper slope, then the marginal product is positive and rising. If the total product curve has a positive and decreasingly steeper slope, then the marginal product is positive but falling.

                           SCARCE GOOD: A tangible item produced with society's limited resources for the purpose of satisfying wants and needs. As a general notion, the phrase scarce good can also commonly include intangible services produced with society's limited resources for the purpose of satisfying wants and needs. A synonymous term for scarce good is economic good. Adding the word "scarce" before the word "good" signifies that a good has limited availability relative to desired use and is thus subject to economic analysis. A scarce good is typically exchanged through a market. Buyers pay a price to obtain the good and sellers give up the good in exchange for payment.ScarcityAs the name suggests, a scarce good is closely related to the fundamental problem of scarcity. Scarcity is the widespread condition of limited resources and unlimited wants and needs. A scarce good is more specifically a good with limited availability relative to desired use. Scarcity is the general problem underlying the study of economics and a scarce good is a specific good that reflects this general scarcity condition.The contrasting notion to a scarce good is a free good. A free good is one that is plentiful enough to satisfy all desires uses, often with some left over. Market ExchangesBecause limited availability means that a scarce good has more uses that it can meet, it is generally exchanged through a market. The market price serves to allocate the good to its most satisfying and valuable uses. Users gaining the greatest benefit from the scarce good are willing to pay the highest price and can thus out bid other potential users to gain control. Moreover, payment received by those who produce or otherwise have control of the scarce good compensates for the opportunity cost of foregone alternatives.Scarce ResourceThe word "scarce" is also added to the word "resource" to reflect a similar concept. The difference is that a scarce resource is used to produce a scarce good. The resource is transformed or used for production and the good is then used to provide satisfaction. However, in both cases the item is limited relative to the desired use.More than MarketsAlthough most scarce goods are traded through markets, some are directly produced or provided by government. In addition to limited availability relative to desired use, the market exchange of a scarce good also requires rival consumption and nonpayer excludability. Scarce goods that do not have rival consumption and/or nonpayer excludability are termed public goods, near-public goods, or common-property goods. But they are scarce goods nonetheless.A Word About ShortagesAt first glance, a market shortage would seem to be the primary source of a scarce good, that the two are one and the same thing. A closer look, though, reveals otherwise. A shortage depends on the existing market price. If the market price is below the equilibrium price, then the quantity demanded exceeds the quantity supplied AT THE MARKET PRICE, and a shortage results. However, at a different price, the shortage vanishes. In contrast, a scarce good exists if the desired use exceeds the available quantity at a ZERO price. While a scarce good might experience a shortage, it can also experience a surplus, if the price is such that quantity supplied exceeds quantity demanded.
