Traditional economy

Explanation:

"Traditional economy" relies on tradition when it comes to its business transactions. It is common in non-developed and some developing countries where the markets are still emerging. It relies on hunting, fishing, farming and gathering. It doesn't use money, instead it relies on the system of "barter."
