    en.wikipedia.org/wiki/Free_good

    [1] [2] A free good is available in as great a quantity as desired with zero opportunity cost to society. A good that is made available at zero price is not necessarily a free good.

    en.wikipedia.org/wiki/Comparative_advantage

    A good can be produced at a lower relative opportunity cost or autarky price, i.e. at a lower relative marginal cost prior to trade.
