A few notes on teaching this unit


Watch Out for These Misconceptions

  • A country should only trade if it is the best at producing something (Absolute Advantage).

    Comparative advantage shows that trade is beneficial even if one country is better at everything, as long as opportunity costs differ. A simple numerical example with two students 'producing' homework and chores helps clarify this.

  • Trade always benefits everyone within a country equally.

    While trade grows the overall economy, specific industries may decline due to foreign competition. A role play representing 'winners' (exporters) and 'losers' (declining industries) helps students see the social complexities of trade.
