This study considers the interpenetration of criminal and lawful economic activities, with new technologies and unregulated terrains offering new opportunities for new types of interpenetration. We explore the possibility of differentiating, regulating, and controlling criminal and legal activities and markets, the level of control technically feasible and socially and economically desirable, among other relevant issues.  We analyse the following issues, among others:

• Is there a possibility of differentiating and controlling criminal and legal markets and economic activities? 
• What level of control is technically feasible and (at the same time) socially and economically desirable?  
• To some extent is it possible to establish the lawful origins of funds used in every transaction?  
  
  The study is relevant for several reasons:
• Crimes have wide-ranging, major impacts on the economy, society and environment, when connected to lawful economic activities.Quite often these connections (“interpenetrations”) are not detected  - or not reported for various reasons.
• Economic hardship and crises are likely to reinforce the incentives for committing criminal economic activities.
• New technologies might offer new opportunities for new or “refined” criminal economic activities.
• Economic criminals are often innovative and enter unregulated terrains (e.g.,some commons, metaverse, etc.).
• Lack of resources and skills to fight economic crime is a major hurdle.
