Why Do Prices Stick? The Mystery of Sticky Prices

Imagine you have a lemonade stand. Even if lemons get cheaper next door, you might not change your price right away because writing new signs takes time and effort. This is called sticky prices. It means prices don't move as fast as the things that make them expensive or cheap.

It costs money to change prices. If you have to hire someone to reprint menus, update computer systems, or just stand there explaining why the cost went up, it might be easier to keep the old price for a while. This is known as menu costs. Also, people get confused if prices jump around too much, so stores prefer stability.

When demand drops (fewer kids want lemonade), instead of lowering the price immediately, some shops might just sell fewer cups. They keep the price high and lose customers instead of cutting revenue. This can make economic problems last longer than they should. So, sticky prices act like glue holding them in place until enough pressure builds up to break them free.
