The traditional economy types are economies that tend to stick to what is known to them, and what they know for sure is functioning. The progress of these economies is slow, and they very rarely, and very gradually implement newer methods and practices. This is way it is common that in this types of economies the trade and the bartering can still be seen as used instead of money, where the people are doing it the old school way, and don't give that much of an importance to the money as a mean for trade.
