➤ How do you calculate comparative advantage in practice?
Calculate comparative advantage by comparing opportunity costs. For two goods, divide units of the forgone good by units of the produced good.

The lower ratio or flatter relative PPF slope indicates comparative advantage, guiding efficient specialization decisions.
