How do prices adjust in a market to reflect supply and demand?

• A. Prices rise without limit.
• B. Prices fall if demand is higher than supply.
• C. Prices adjust to equilibrate quantity supplied and demanded.
• D. Prices are fixed by government policy.

Answer: (C)

Prices in a market act as signals and incentives to balance what producers want to supply with what consumers want to buy. When demand exceeds supply at the current price, a shortage appears and the price tends to rise. Higher prices encourage more production and deter some buyers, until the shortage disappears. When supply exceeds demand, a surplus forms and the price falls, encouraging more buyers and reducing production until the surplus is gone. This adjustment process continues until quantity supplied equals quantity demanded—the market equilibrium. If factors shift supply or demand, the equilibrium price and quantity move to a new balance. Prices fixed by government prevent this natural adjustment, which is why the standard answer is that prices adjust to equilibrate quantity supplied and demanded.
