Introduction to the Demand and Supply Framework

Supply (cont’d)

• Supply Schedule—a table that shows the quantity firms are willing and able to supply at various prices.

• Supply Curve—a graph that shows the quantities that sellers are willing and able to supply at different prices.

Market Supply

• The horizontal sum of all the individual firm supply curves.

The Law of Supply: As price increases (decreases) quantity supplied increases (decreases)

Changes in Supply

• Prices of inputs (such as wages)

• Technology

• Natural disruptions (such as bad weather)

• The number of firms in the market

• Expectations

• Government policies

Changes in Supply (cont’d)

Equilibrium

• The price at which the quantity demanded equals the quantity supplied and the market “clears.” No tendency for price or quantity to change.
