Explanation:

1. The dual - role of prices refers to their rationing and signaling functions. Prices ration scarce resources by determining who gets what, and signal information about consumer preferences and production costs.
2. The equilibrium price of a good or service is determined at the intersection of the demand and supply curves. At this point, the quantity demanded equals the quantity supplied.
3. If there is too much of a good (surplus), the price will tend to fall as producers try to sell excess inventory. If there is too little (shortage), the price will tend to rise as consumers compete for the limited quantity.
4. The government might get involved in setting prices to correct market failures (e.g., externalities, public goods), protect consumers (e.g., price - ceilings on essential goods), or protect producers (e.g., price - floors for agricultural products).

Answer:

1. The dual role of prices is their rationing and signaling functions.
2. The equilibrium price is determined at the intersection of the demand and supply curves.
3. Surplus leads to price - fall, shortage leads to price - rise.
4. To correct market failures, protect consumers or producers.
