Political - Typically use their power in ways that are not allowed to gain benefit to themselves, such as politicians who get rich in office, and gain favors for caving to special interests.
Economic - This would be like a business that lies or falsified information to cheat or deceive customers or other businesses to make money illegally.
Organized crime - They use all sorts of methods, hence the name organized crime. Some of them have good organizational structures similar to legitimate businesses, but typically they are serving products, or doing things that are highly illegal like selling drugs, or scamming people, or computer hacking.
