Final answer:
A person with an absolute advantage in all goods will have a comparative advantage only in some goods, not all, because comparative advantage is determined by lower opportunity costs. Trade can still be beneficial, even if one party has an absolute advantage, by focusing on goods with a comparative advantage.
Step-by-step explanation:
A person who has an absolute advantage in the production of all goods will not necessarily produce all goods at the lowest opportunity cost. Having an absolute advantage means being able to produce more of a good per unit of labor than someone else. However, comparative advantage is about producing goods at a lower opportunity cost, not just producing more. Therefore, the correct answer is that the person will have a comparative advantage in the production of only some goods and not others.
Comparative advantage drives trade because it is more efficient for countries (or individuals) to specialize in the production of goods for which they have a lower opportunity cost, and then trade with others to acquire different goods or services. This specialization and trade can lead to increased global production and consumption.
So, even if a person has an absolute advantage in producing all goods, they might gain from specializing in the production of the goods for which they have a comparative advantage. Other countries or individuals might still be more efficient in producing other goods when opportunity costs are considered.
