Answer
Hi,
If the opportunity cost of producing a particular good is lower for one producer than another, the former producer has comparative advantage for producing the good.
Explanation
A comparative advantage occurs when a producer is able to produce goods by using fewer resources at a lower opportunity cost. Increasing the production of one good will mean that less goods for another can be produced. This theory is advantageous in free trade because a producer can be able to realize higher output gains by selling goods in which he or she enjoys comparative advantage.
Best wishes!
