Instructions: Explain why a particular gain/loss/n.p./n.b.e occurs.

A satisfactory answer will:

• state what the relevant definition of well-being is for the group I pick in that exact model;
• explain what the basis for trade is in that model;
• then explain what happens when trade starts;
• clearly connect that change to the definition of well-being to show why the answer you choose was a gain or a loss;
• must be written in full sentences, use relevant key terms, and use the key terms correctly.
