In a market economy, prices are determined by the interaction of supply and demand. The equilibrium price is the market price where the quantity demanded equals the quantity supplied. At this point, the market clears and there is no shortage or surplus.
The law of supply states that as prices rise, the quantity supplied increases, and as prices fall, the quantity supplied decreases. The law of demand states the opposite - as prices rise, the quantity demanded falls, and as prices fall, the quantity demanded increases.
The supply and demand curves represent these relationships graphically. The point where they intersect determines the equilibrium price and quantity.
Problem: If the demand for smartphones increases due to new features, what happens to the equilibrium price and quantity?
Solution:
The price system allocates resources efficiently in a market economy. Higher prices incentivize producers to supply more, while lower prices encourage consumers to demand less. At the equilibrium price, resources are allocated to their most valued use, maximizing societal welfare.
However, market failures like externalities, public goods, and imperfect competition can lead to inefficient resource allocation. In such cases, government intervention may be necessary to correct market failures and promote efficiency.
