Absolute advantage is to resource efficiency as comparative advantage is to:

Comparative advantage is related to opportunity cost, which is the cost of what you give up to do something else. While absolute advantage focuses on who can produce more of a good with the same resources, comparative advantage looks at who can produce a good at a lower opportunity cost. For example, if one country can make both cars and computers more efficiently than another country, it has an absolute advantage in both. However, if that country is much better at making cars than computers, it should focus on cars, allowing the other country to specialize in computers if it has a lower opportunity cost for that. This way, both countries can trade and benefit from their specializations, leading to greater overall efficiency.
