 MARKET DEMAND: The total demand of every individual willing and able to buy a good. Market demand is found by combining the individual demands of everyone willing and able to buy a particular good. The market demand curve is found by horizontally adding all individual demand curves, that is, sum up the quantities demanded by all buyers at each and every price. Market demand operates according to the law of demand, as illustrated by a downward-sloping market demand curve. For higher prices the quantity demanded by all buyers in the market combined is less than the quantity demanded for lower prices.

SUPPLY CURVE:

A graphical representation of the relation between the supply price and quantity supplied, holding all ceteris paribus supply determinants constant. A supply curve graphically illustrates the law of supply, the direct relation between supply price and quantity supplied for a particular good. It is one half of the standard market model. A demand curve is the other half.
A supply curve is a useful graph that can summarize several of the more important aspects of supply. It graphically illustrates the law of supply and when combined with the demand curve forms the market model, one of the most useful tools found in economic analysis.

### Plotting the Numbers

A supply curve is commonly derived from a simple supply schedule, such as the one for stuffed Yellow Tarantulas, a cute and cuddly stuffed creature from the Wacky Willy Stuffed Amigos line of collectibles, shown in this exhibit. This schedule illustrates the law of supply relation between supply price and quantity supplied. As the supply price increases from \$5 to \$50, the quantity supplied increases from 0 to 900 Yellow Tarantulas.
Supply ScheduleSupply Curve

Transferring the price-quantity pairs from the supply schedule to a graph reveals the supply curve for stuffed Yellow Tarantulas. This task is easily accomplished by clicking the [Plot] button. A \$5 price is associated with 0 stuffed animals, a \$10 price goes with 100 stuffed animals, and on it proceeds, until finally a \$50 price is paired with 900 stuffed animals.

The supply curve is finalized by connecting these 10 points with a continuous line. The 10 prices corresponding to these 10 points, are but 10 of an infinite number of prices, each with a corresponding quantity. A continuous line includes these other possibilities. To reveal this line, click the [Draw] button. The end result is the supply curve.

### What It All Means

• First, as the price increases from a low of \$5 to a high of \$50, the quantity supplied of Yellow Tarantulas increases from 0 to 900. Higher prices are related to larger quantities. This relation, this direct relation between supply price and quantity supplied, IS the basic law of supply.

• Second, the supply curve represents maximum quantities and minimum prices. That is, if the price is \$10, then the maximum quantity supplied is 100 Yellow Tarantulas. It is not 150, nor even 101, but only 100. Alternatively, if sellers offer 100 Yellow Tarantulas for sale, then the minimum supply price they are willing and able to accept is \$10, not \$5, not even \$9.99, but \$10.

• Third, this whole curve, every price-quantity combination on the curve, is supply. Supply is the entire range of prices and quantities, all pairs. Supply is the entire curve. In contrast, quantity supplied is any specific number of Yellow Tarantulas sellers are willing and able to sell at a specific supply price. Selecting a different price generates a different quantity supplied. Quantity supplied is a point on the curve.

• Fourth, this supply curve represents hypothetical possibilities. It suggests a "What if" relation between supply price and quantity supplied. It indicates quantity supplied given a supply price, or supply price given the quantity supplied. If, for example, the supply price is \$10, then sellers are willing and able to sell 100 Yellow Tarantulas. This does not mean that sellers will sell, are selling, or ever will sell 100 Yellow Tarantulas. It only indicates what they would sell at a \$10 price.
