What are prices act as signals?

Prices act as signals, like a friendly message from one person to another about what’s going on in the world.

Imagine you and your friend both want to buy the same toy at the store. If the toy is really popular, the store might raise its price because more people are asking for it. That higher price is like a signal saying, “This toy is super cool right now, maybe wait a bit or think about if you really need it.”

On the other hand, if no one wants that toy anymore, the store might lower its price to get rid of it faster. That lower price is like a signal saying, “Hey, this toy isn’t as popular anymore, maybe it’s a good time to grab it!”

Think of prices like a playground game. If everyone wants to play on the swings at the same time, there might be more kids waiting in line, that's like a higher price because you have to wait longer. But if only a few people want to swing, it’s easier to get on right away, that's like a lower price.

Prices help people make smart choices without having to talk to each other every time. It’s like having a little helper who tells you when something is in demand or not! Prices act as signals, like a friendly message from one person to another about what’s going on in the world.
