The story
Where this fits in Marginal Falls
The port opens, and the town must decide what to make and what to obtain through exchange. Comparing opportunity costs shows why a town can gain from trade even when its trading partner is more productive at making every good.
A question to take into class
If another town can produce both goods using fewer resources, can Marginal Falls still benefit from trading with it?
