    The Effect of Price on Supply

    Just as the relationship between price and demand is governed by basic economic law, supply and price are directly linked. We will now explore the ways in which changes in price affect supply.

    Suppliers Follow the Law of Supply


    Supply is the amount of a good or service that is available.

    According to the law of supply, producers offer more of a good or service as its price increases and less as its price falls.

    Economists use the term quantity supplied to describe how much of a good or service a producer is willing and able to sell at a specific price.

    The Effect of Price on Production


    If a firm is already earning a profit by selling a good or service, then an increase in the price—ceteris paribus—will increase the firm’s profits. The promise of higher revenues generated by each sale encourages the firm to produce more.

    The Effect of Price on Number of Suppliers

    One of the benefits of the economic system of the United States, with its emphasis on free markets, is that markets are open to new suppliers. Entrepreneurs can enter growing markets to respond to these trends as long as they can assemble the needed factors of production and are willing to take the risk.

    Understanding Supply Schedules

    Similar to a demand schedule, a supply schedule shows the relationship between price and quantity supplied for a specific good or service, or how much of a good or service a supplier will offer at various prices.

    All Suppliers and the Market Supply Schedule

    All of the supply schedules of individual firms in a market can be added up to create a market supply schedule. A market supply schedule shows the relationship between prices and the total quantity supplied by all firms in a particular market.

    The Supply Graph

    When we graph the data points in the supply schedule, we create a supply graph—also known as a supply curve. A supply curve is a graphic representation of a supply schedule. A supply curve is very similar to a demand curve, except that the horizontal axis now measures the quantity of the good supplied, not the quantity demanded.

    Elasticity of Supply Over a Short Time

    An orange grove is one example of a business that has difficulty adjusting to a change in price in the short term. Orange trees take several years to mature and grow fruit. If the price of oranges goes up, an orange grower can buy and plant more trees, but he will have to wait several years for this investment to pay off.

    Elasticity of Supply Over a Longer Time

    Like demand, supply becomes more elastic over time. The orange grower could not increase his output much when the price of oranges rose, but he can plant more trees to increase his supply over time. After several years, he will be able to sell more oranges at the higher price.
