a. Show that easterners have a comparative advantage in the production of defense. b. Suppose this country has decided it wants to produce 60 units of defense.

Suppose further that it drafts 20 westerners and 20 easterners (who together will produce 60 units of defense). How much food will the country produce if it chooses to have a military draft? e. Compare the cost in terms of foregone food production under a draft to the cost under a volunteer army where the country pays the easterners enough to persuade them to become soldiers.
