BLACK MARKET: An illegal market in which the price of the goods sold is above a legally set maximum price. A black market invariable results whenever the government imposes a price ceiling on a good. A common example of a price ceiling is rent controls on apartments in many large cities.

In so doing, they have entered into the realm of black markets.
