Final answer:
A common market is an economic agreement that allows for the free movement of goods, services, labor, and capital, and adopts a unified external trade policy among member nations.
Step-by-step explanation:
The blank in the question can be filled with the phrase common market. A common market is an economic agreement between countries that eliminates all tariffs and other restrictions on internal trade, adopts a common set of external tariffs, and removes all restrictions on the free flow of capital and labor among member nations.
