Collusion refers to a secret agreement between two or more parties to deceive or defraud others. This often occurs in business or legal contexts, where individuals or organizations work together to manipulate outcomes, such as fixing prices or rigging bids. The goal of collusion is typically to gain an unfair advantage or profit at the expense of others. In many jurisdictions, collusion is considered illegal and can lead to severe penalties, including fines and imprisonment. It undermines fair competition and can harm consumers by leading to higher prices and reduced choices. Authorities often investigate suspected collusion to maintain market integrity.
