Market Equilibrium
Explain why the equilibrium price of a commodity is determined at that level of output at which its demand equals its supply.
Suppose demand is greater than supply. Since the buyers will not be able to buy all what they want, there will be competition among the buyers. It will have an upward influence on the price. As a result, demand will start falling and supply starts rising. It will go on till the demand is equal to supply again. If demand is less than supply, the sellers will not be able to sell all what they want, there will be competition among the sellers. It will have a downward influence on the price. As a result, demand will start rising and supply starts falling. It will go on till the demand is equal to supply again. Hence, the equilibrium price of a commodity is determined at that level of output at which its demand equals its supply.
