Answer:
An economic union
Explanation:
Economic integration can be defined as a strategic trade arrangement between countries to eliminate or mitigate trade barriers, as well as coordinate fiscal and monetary policy among its members.
Trade can be defined as a process which typically involves the buying and selling of goods and services between a producer and the customers (consumers) at a specific period of time. There are different types of market or trade bloc used in economic integration and these includes;
I. Customs union
II. Free trade area
III. Common market
IV. Political union
VI. Economic union
An economic union can be defined as a trade bloc which comprises of both customs union and a common market.
In a common market, there are free movement of the factors of production and no barrier to trade between member countries. Also, a common market establishes a common external trade policy for non-member countries.
However, an economic union entails even closer economic integration and cooperation among member countries than a common market because it combines customs union and a common market.
