The market is made up of buyers or consumer and sellers or suppliers. The interaction between forces of demand and supply and the pricing signals is known as market dynamics. The fluctuation of price in market is due to the law of supply and demand. This market dynamic tends to lead to a intersection point where the quantity of a good demanded equals the quantity supplied, also known as the equilibrium price.
The force of supply and demand determine the market dynamics. Both the supply and the demand obey to a particular law. The law of supply and demand explains the effect that the availability of a particular good and the desire for that product has on price.
The market demand is the total quantities of a good or service people are willing and able to buy at alternative prices in a given time period; the sum of individual demands. The market demand is determined by the number of potential buyers and their respective tastes, incomes, other goods, and expectations. Law of Demand states that the quantity of a good demanded in a given time period increases as its price falls, ceteris paribus meaning nothing else changing.
On the other hand we have the supply. The total quantities of a good that sellers are willing and able to sell at alternative prices in a given time period. The law of supply explains that the quantity of a good supplied in a given time period increases as its price increases, ceteris paribus.
Quantity, supply and demand can be represented graphically as functions. The point where the supply function and demand function are is called the equilibrium price. The equilibrium price is defined as the price at which the quantity of a good demanded
