What Shifts the Supply Curve?

What shifts the supply curve? Anything that changes a supplier's costs. Learn how input costs, technology, taxes, trade, and even expectations shift supply in economics.

You’ll learn:

• Why higher costs shift supply up and to the left
• Why lower costs shift supply down and to the right
• How improvements in technology increase supply
• How taxes, subsidies, and input prices affect producers
• How trade and market entry affect supply
• How opportunity costs and expectations influence supply

Using clear examples—from strawberries and blueberries to lumber, bagels, and orange juice—we show how economists think about supply shifts in the real world.
