To understand the model, we should first think about 'Supply', and then consider 'Demand'; before putting the two concepts together.

In simple terms:

• Supply is the amount of something that providers are willing to bring to the market (i.e. supply) at a given price.
• Demand is the amount of something that consumers want to buy (or demand) at a given price. ^[1]

So what is Supply and Demand? This is an economic model where the price at which a good (a product or service) is sold is controlled by the good’s level of supply, and its demand. If the supply of a good is equal to its demand, there is an economic equilibrium, and the good is sold at a stable price which buyers and sellers are happy with.

However, Supply and Demand can (and often does) fluctuate. When the supply of a good is greater than the demand for that good, there is a surplus. On the other hand, when demand for a good is greater than the supply, then there is a shortage. In January 2017, for instance, there was a shortage of courgettes in the UK due to bad weather across Europe ^[2]. This resulted in either no supply available to many supermarkets or, where supply was possible, the price rose from £6 or £7 per box to £20 per box. In another example, there is a housing shortage in New Zealand (so demand is greater than supply), and this is forcing the house prices to jump to record highs. ^[3]
