Correct Option
The correct option is 2 and 3 only.
Explanation
Market equilibrium is determined where the quantity demanded by consumers equals the quantity supplied by producers. In a perfectly competitive market with a fixed number of firms, the price mechanism acts as an invisible hand to correct imbalances (excess demand or excess supply) and restore equilibrium.
Statement-wise Analysis
- Statement 1 is Incorrect.
If the prevailing market price is lower than the equilibrium price, the quantity demanded by consumers will exceed the quantity supplied by producers (due to the Law of Demand and Law of Supply). This situation creates excess demand (shortage), not excess supply. Excess supply occurs when the price is higher than the equilibrium price.
- Statement 2 is Correct.
In a situation of excess demand, consumers compete for the limited available quantity of goods. This competition drives the price upward. As buyers bid higher prices to secure the good, the market price tends to increase.
- Statement 3 is Correct.
This statement describes the adjustment mechanism following excess demand. As the market price rises:
- Quantity demanded falls (movement up along the demand curve).
- Quantity supplied increases (movement up along the supply curve).
Key Takeaway
Key Takeaway: When price is below equilibrium, excess demand occurs, causing prices to rise. When price is above equilibrium, excess supply occurs, causing prices to fall. These adjustments move the market toward the equilibrium price where quantity demanded equals quantity supplied.
