Terms You May Have Heard:
Comparative advantage: the ability of one country to produce a good or service more efficiently than another country as determined by their opportunity costs. We compare two goods when talking about comparative advantage, like producing cars and airplanes. A country cannot have a comparative advantage in both goods, since the test is which one it can produce more efficiently.
Trade deficit: the amount by which the cost of a country's imports exceeds the value of its exports.
