What Shifts the Supply Curve?
Alex TabarrokGeorge Mason University
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.
