Introduction: What is Price Theory?

Price theory is all about why things cost what they do, and how people decide to buy or not buy them.

Imagine you're at a candy store. There are two kinds of candy: chocolate bars and gummy worms. Chocolate bars cost 5 coins, and gummy worms cost 3 coins. If you have only 4 coins, you can’t get the chocolate bar, it’s too expensive. But if you really want a treat, maybe you’ll choose the cheaper one instead.

Now imagine the store owner decides to lower the price of chocolate bars to 2 coins. Suddenly, more people might buy them because they’re cheaper and still taste good. That’s how price theory works, it helps us understand what happens when prices go up or down and how that affects choices.

When something is cheap, like gummy worms, you’re more likely to buy it. When something is expensive, like chocolate bars at first, you might not buy it unless you really want it.

Think of it like choosing between your favorite toy or a new one, if the new one costs too much, you’ll stick with what you know! Price theory is all about why things cost what they do, and how people decide to buy or not buy them.
