Answer:
The false statement about assigning work based on comparative advantage is "assign the person who is fastest or best at a task to do that task."
Comparative advantage is the ability of an individual or group to carry out an economic activity at a lower opportunity cost than another individual or group. It is based on relative efficiency, not absolute efficiency. Therefore, even if one person can produce all goods and services more efficiently than another person, there is still a benefit to specialization and trade based on comparative advantage.
The principle of comparative advantage suggests that workers should specialize in the tasks for which they have a lower opportunity cost, and trade with others who have a higher opportunity cost for those tasks. In this way, everyone can benefit from the gains in productivity and efficiency that come from specialization and trade.
Therefore, the statement "the person who has absolute advantage in the task will sometimes be assigned to do it" is also true, but it is not the only factor to consider when assigning work based on comparative advantage. The key is to assign tasks based on the relative opportunity costs of the workers involved, not just their absolute abilities.
