Problem
Migration in the apple and computer economy: In the apple-computer example, suppose people in the North have the right to charge an "entrance fee" to immigrants. Assume the world starts from the position of free trade and considers moving from free trade to free migration. Find an entrance fee (a certain number of apples and a certain number of computers paid each period) that the North can charge so that workers in both the North and the South will be better off.
