The article is devoted to International Organized Crime (IOC) issues. The authors analyzed questions related to measuring of the harm resulting from international organized crime particularly economic harm caused by IOC groups and other impacts, such as human misery, public safety and threats to free commerce. Authors suggested five hypotheses can be broken down into five sub-hypotheses based on the characteristics of criminal organizations:
1. The more sophisticated the criminal organization, the larger its harm capacity.
2. The more complex the structure of the criminal organization, the larger its harm capacity
3. The more a criminal organization exhibits stability, the more likely it is to cause harm.
4. The stronger the self-identification exhibited by members of a criminal organization, the more likely it is to cause harm.
5. The greater a criminal organization's authority of reputation, the larger its harm capacity.
