Conclusion Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much quantity of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship.
Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain good producers are willing to supply when receiving a certain price. The correlation between price and how much of a good or service is supplied to the market is known as the supply relationship.
Price, therefore, is a reflection of supply and demand. The relationship between demand and supply underlie the forces behind the allocation of resources.
In market economy theories, demand and supply theory will allocate resources in the most efficient way possible. Let us take a closer look at the law of demand and the law of supply.
The Law of Demand The law of demand states that, if all other factors remain equal, the higher the price of a good, the less people will demand that good.
In other words, the higher the price, the lower the quantity demanded. The amount of a good that buyers purchase at a higher price is less because as the price of a good goes up, so does the opportunity cost of buying that good. As a result, people will naturally avoid buying a product that will force them to forgo the consumption of something else they value more.
The chart below shows that the curve is a downward slope. A, B and C are points on the demand curve. Each point on the curve reflects a direct correlation between quantity demanded Q and price P.
So, at point A, the quantity demanded will be Q1 and the price will be P1, and so on. The demand relationship curve illustrates the negative relationship between price and quantity demanded. The higher the price of a good the lower the quantity demanded Aand the lower the price, the more the good will be in demand C.
The Law of Supply Like the law of demand, the law of supply demonstrates the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied.
Producers supply more at a higher price because selling a higher quantity at a higher price increases revenue. A, B and C are points on the supply curve. Each point on the curve reflects a direct correlation between quantity supplied Q and price P.
At point B, the quantity supplied will be Q2 and the price will be P2, and so on. To learn how economic factors are used in currency trading, read Forex Walkthrough: Time and Supply Unlike the demand relationship, however, the supply relationship is a factor of time.
Time is important to supply because suppliers must, but cannot always, react quickly to a change in demand or price. So it is important to try and determine whether a price change that is caused by demand will be temporary or permanent. If, however, there is a climate change, and the population will need umbrellas year-round, the change in demand and price will be expected to be long term; suppliers will have to change their equipment and production facilities in order to meet the long-term levels of demand.
If, however, the ten CDs are demanded by 20 people, the price will subsequently rise because, according to the demand relationship, as demand increases, so does the price.
Consequently, the rise in price should prompt more CDs to be supplied as the supply relationship shows that the higher the price, the higher the quantity supplied. If, however, there are 30 CDs produced and demand is still at 20, the price will not be pushed up because the supply more than accommodates demand.
In fact after the 20 consumers have been satisfied with their CD purchases, the price of the leftover CDs may drop as CD producers attempt to sell the remaining ten CDs. Equilibrium When supply and demand are equal i.
At this point, the allocation of goods is at its most efficient because the amount of goods being supplied is exactly the same as the amount of goods being demanded.
Thus, everyone individuals, firms, or countries is satisfied with the current economic condition. At the given price, suppliers are selling all the goods that they have produced and consumers are getting all the goods that they are demanding.
As you can see on the chart, equilibrium occurs at the intersection of the demand and supply curve, which indicates no allocative inefficiency. These figures are referred to as equilibrium price and quantity.Price Control – Price Ceiling.
