A black market could arise as a result of:
A. The imposition of a legal price floor above the equilibrium price
B. The imposition of a legal price ceiling below the equilibrium price
C. An increase in demand
D. A decrease in supply
The Correct Answer and Explanation is :
The correct answer is B. The imposition of a legal price ceiling below the equilibrium price.
Explanation:
A black market is an illegal or unregulated market that arises when the prices of goods or services are artificially set too high or too low due to government intervention. The most common cause of a black market is when the government imposes a price ceiling or price floor that disrupts the natural balance of supply and demand.
Price Ceiling (Answer B):
A price ceiling is a maximum allowable price set by the government. If the government imposes a price ceiling below the equilibrium price (the price at which the quantity demanded equals the quantity supplied), it causes a shortage. This is because the low price increases the quantity demanded (since more consumers can afford it) while decreasing the quantity supplied (since producers are less willing to supply the good at the lower price).
In this situation, since the legal price is lower than what the market would naturally set, there is not enough of the good to meet demand. This creates an opportunity for a black market, where goods can be sold at higher prices than the legal ceiling. Sellers may find buyers willing to pay more, and buyers may seek out goods even if they are being sold illegally.
Other Options:
- A. The imposition of a legal price floor above the equilibrium price: A price floor is a minimum price set by the government. If it’s set above the equilibrium price, it causes a surplus of goods (more is supplied than demanded), but it does not directly lead to a black market unless the surplus goods are sold illegally, which is less common.
- C. An increase in demand: An increase in demand, on its own, does not lead to a black market. It simply increases the equilibrium price and quantity.
- D. A decrease in supply: A decrease in supply would typically raise prices, but it does not directly lead to a black market unless there is also a price control involved.
Therefore, the most direct cause of a black market is the imposition of a price ceiling below the equilibrium price.
