As international trade increases, it contributes to a shift in jobs away from industries where that economy does not have a(n) advantage and toward industries where it has a(n) advantage.

Comparative

Explanation:

In the question, the blank can be filled in with the same word (comparative).

A comparative advantage can be defined as "the ability of a group to make a specific product more efficiently than another activity". A good example of this would be a nation producing resources such as oil have a comparative advantage in chemicals, so therefore the nations that produce oil will do so easier that other nations who do not have oil wells. This then forces the nations who cannot provide oil to move away from that business because it is too expensive to compete with other nations. They would then move to another industry where they would have a comparative advantage over any other nation that may try to compete.
