LAW OF SUPPLY: The direct relationship between supply price and the quantity supplied, ceteris paribus. This fundamental economic principle indicates that as the price of a commodity increases, then the quantity of the commodity that sellers are able and willing to sell in a given period of time, if other factors are held constant, also increases. This law, while not quite as iron-clad as the law of demand, is quite important to the study of markets.

MARKET-CLEARING PRICE:

The price that exists when a market is clear of shortage and surplus, or is in equilibrium. Market-clearing price is a common, non-technical term for equilibrium price. In a market graph, the market-clearing price is found at the intersection of the demand curve and the supply curve.
Market-clearing price is the price that achieves a market balance. Because quantity demanded and quantity supplied are equal at the market-clearing price, there is no shortage nor surplus in the market, which means that neither buyers nor sellers are inclined to change the price, which is the primary condition for equilibrium.

Moreover, because the market-clearing price also simultaneously equates the demand price and supply price, the market equilibrium generates an efficient allocation of resources (presuming competition and no market failures).

Clearing the Market

Market-clearing Price
The market model displayed in the exhibit to the right can be used to identify the market-clearing price. This particular model represents the market for 8-track tapes, which are filled with the works of classic performers such as The Carpenters and Englebert Humperdink. The buyers and sellers happen to be folks attending the 88th Annual Trackmania 8-Track Tape Collectors Convention at the Shady Valley Exposition Center.

The market-clearing price achieves a balance in the market, which is equality between quantity demanded and quantity supplied. In other words, it clears the market of any shortage or surplus. The only price that accomplishes this task is at the intersection of the demand curve and supply curve. This intersection point, and the price that achieves it, can be identified by clicking the [Market-Clearing Price] button in the exhibit.

Doing so reveals a market-clearing price of 50 cents. At this price, the demand curve and supply curve intersect. The quantity demanded is 400 tapes and the quantity supplied is 400 tapes. The quantity demanded is equal to the quantity supplied. The buyers can buy all that they want, so there is no shortage. The sellers can sell all that they want, so there is no surplus. Neither buyers nor sellers are motivated to change the price. The forces of demand and supply are in balance.

This is the ONLY price that achieves a balance between these two quantities. Best of all, because this is equilibrium, the market-clearing price of 50 cents will not change and the equilibrium quantity of 400 tapes will not change unless or until an external force intervenes.

Today, you are likely to spend a great deal of time flipping through mail order catalogs wanting to buy either a Boston Red Sox baseball cap or a square lamp shade with frills along the bottom. Be on the lookout for deranged pelicans.
Your Complete Scope

This isn't me! What am I?

A scripophilist is one who collects rare stock and bond certificates, usually from extinct companies.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover."

-- Mark Twain
