Have you ever wondered why prices for certain products go up while others drop? There is a powerful economic principle behind all price changes. The principle is supply and demand. Supply and demand play a crucial role. This applies to the cost of housing. It also applies to the price of petrol and the discount on your favourite clothing brand.
The forces of supply and demand drive market prices. They dictate how much of a product is available and how much people want it. This model is simple, yet it is one of the most important in economics. It explains much of the price fluctuation we experience every day.
In this blog, we’ll explore how supply and demand work. We will examine what causes shifts in these curves. We’ll also see how this concept applies to real-world scenarios like the housing market and petrol prices. If you’re preparing for your A-Level Economics exams, this blog will help you master these key principles. You will be able to apply them in academic and everyday contexts.

FAQs
What is the supply and demand model?
The supply and demand model is an economic framework that explains how prices are determined in a market. It shows the relationship between the quantity of a product that consumers are willing to buy, known as demand. It also shows the quantity that producers are willing to sell, known as supply.
How do changes in consumer preferences affect demand?
Changes in consumer preferences can significantly impact demand. If a new health trend favours plant-based diets, the demand for plant-based foods will likely increase. This increase can cause a shift in the demand curve to the right. Conversely, if a product falls out of favour, demand may decrease, shifting the curve to the left.
What factors can cause a shift in the supply curve?
Several factors can cause a shift in the supply curve. These factors include changes in production costs. Technological advancements and government regulations also play a role. Additionally, the number of sellers in the market can cause shifts. For example, if a new technology reduces production costs, the supply curve will shift to the right. This indicates an increase in supply.
What happens at market equilibrium?
Market equilibrium occurs when the quantity supplied equals the quantity demanded at a specific price. At this point, there is no surplus or shortage of goods, and the market is considered stable. If there is a shift in supply or demand, the equilibrium price will adjust to reflect the new market conditions.
Why is understanding supply and demand important for everyday consumers?
Understanding supply and demand helps consumers make informed decisions about their purchases. By recognising how these forces affect prices, consumers can better anticipate price changes.
