Which of the following is a gain from trade?

Question

Quizplus · Accepted Answer

Trade allows countries to specialize in producing goods and services that they have a comparative advantage in, and then trade with other countries for goods and services that they don't have a comparative advantage in producing. This results in increased efficiency, lower costs, and increased output, which ultimately leads to a higher standard of living for all trading countries. B and C are not gains from trade, as a shorter workweek and self-sufficiency do not necessarily lead to an increase in overall well-being or economic growth.
