Illegal market where goods are traded at prices or quantities above legal limits?

• A. Market equilibrium
• B. Monopoly
• C. Black market
• D. Perfect competition

Answer: (C)

When the government sets price or quantity limits, some transactions move outside the official market. This underground trading is a black market, where goods are bought and sold illegally and can involve prices or quantities that exceed legal restrictions. The high prices or larger-than-allowed quantities arise because buyers want access despite the limits and sellers are willing to take the risk of penalties to profit from the shortage created by the restrictions. This concept is distinct from market equilibrium, which is simply where supply and demand meet in an allowed market; from monopoly, which is about a single seller wielding market power; and from perfect competition, which describes a large number of buyers and sellers in a legal, unrestricted setting.
