Have you ever visited a shop and noticed that the price of a product was higher than it was last week? Or have you waited for a discount because you thought the price might fall?

Prices change all the time. Sometimes the reason is higher production costs. Sometimes a product becomes very popular. In other cases, there may not be enough of that product in the market.
To understand these changes, we need to learn about two important economic ideas: supply and demand.
The words may sound technical, but we see supply and demand in our daily lives almost every day.
What Is Demand?
Demand means how much of a product or service people want to buy at a certain price.
Imagine that a cup of coffee costs $2. Many people may want to buy it. But if the same coffee suddenly costs $10, some customers may decide not to buy it. They may make coffee at home or choose a cheaper drink.
In general, when the price of a product rises, people usually want to buy less of it. When the price falls, they may want to buy more.
However, price is not the only thing that changes demand. Income, seasons, habits, trends, and personal needs can also affect it.
For example, demand for umbrellas usually increases on rainy days. Demand for cold drinks may rise during a hot summer. If a famous person uses a certain product, that product may suddenly become more popular.
What Is Supply?
Supply means how much of a product or service sellers are willing and able to offer at a certain price.
Imagine that strawberries are easy to grow during a certain season. Farmers produce many strawberries, so there is a large supply in the market. When the season ends, fewer strawberries are available.
If many sellers have the same product, they usually compete with each other. This competition can help keep prices lower.
But when only a small amount of a product is available, its price may rise, especially if many people still want to buy it.
Supply can change for many reasons. Weather conditions, energy prices, transportation costs, worker shortages, and problems in production can all affect how much of a product reaches the market.
What Happens When Demand Is Higher Than Supply?
Let’s imagine that a popular singer announces one concert with only 5,000 tickets. However, 50,000 people want to attend.
There are many buyers but only a limited number of tickets. Demand is much higher than supply. As a result, tickets may sell very quickly, and their prices may rise.
We can see the same situation in the housing market. If many people want to live in a city but there are not enough homes, rents may increase.
This connects directly to scarcity, which we discussed in our first lesson. A product becomes more valuable when it is limited and many people want it.
What Happens When Supply Is Higher Than Demand?
Now imagine that a clothing store has 500 winter coats, but winter is almost over. Customers are no longer interested in buying them.
The store has a large supply, but demand is low. It may reduce the prices to sell the remaining coats. This is why we often see seasonal discounts.
A similar situation can happen with food. A market may lower the price of fresh products before they expire. It is better to sell them at a lower price than not sell them at all.
Prices Send Messages
Prices do more than show us how much something costs. They also send messages to buyers and sellers.
A rising price may tell producers that people want more of a product. Businesses may then try to produce more. A falling price may tell them that demand is weak or that too much has been produced.
For consumers, prices help us make choices. If one product becomes too expensive, we may look for another option, wait for a discount, or decide that we do not really need it.
Of course, real markets are not always simple. Taxes, government rules, global events, production costs, and competition can also influence prices. Still, supply and demand give us a useful starting point.
Economics Is All Around Us
The next time you see the price of coffee, rent, fruit, or a concert ticket change, ask yourself two questions:
Has demand changed? Has supply changed?
You may not always find one simple answer. Sometimes several factors work together. But these questions can help you understand what is happening behind the price.
Supply and demand are not only ideas in economics books. They are part of our shopping decisions, business choices, and everyday lives.
Discussion question: Can you think of a product whose price recently changed because of supply or demand?
