What is Aggregate supply (AS)?

Aggregate supply is what a whole country makes when it’s working hard to create goods and services.

Imagine your school has a bake sale every week. All the students bring their favorite treats, cookies, cupcakes, brownies, and sell them in the cafeteria. That's like aggregate supply, it's all the things that a country can make if everyone is working together.

Think of your class as a small economy, just like a country. Each student brings something different to the bake sale, which means they’re each doing their own part. If more students help out by bringing treats, the bake sale gets bigger, that’s like when a country makes more things because more people are working.

Now imagine it's a really busy week, and all your classmates bring treats. The bake sale is super full! That's like aggregate supply going up, more goods being made in the whole economy.

If some students are sick and can't come to school, the bake sale has fewer treats, that’s like aggregate supply going down because not as many people are working.

So aggregate supply is just a fancy way of saying how much stuff a country can make when all its workers are helping out.
