Based on the model analysis of the International Financial Action Group in the first part of this book, we investigated the development of money laundering techniques in different economic sectors: financial sector, commercial, real estate, casinos, gambling and electronic auctions. We emphasize that the description of money laundering techniques in this chapter has a declarative value, and is far from having exhausted the subject. The contemporary peculiarities of money laundering, namely: economic magnitude of the phenomenon, its links of emphasized transnational nature with organized crime, the professionalism of money launderers, etc. is the reason that justifies our interest to turn our attention to the connections that exist between economic-financial crime, especially tax evasion, money laundering, and tax havens.
