When a country has a comparative advantage in the production of a good, it means that it can produce this good at a lower opportunity cost than its trading partner. Then the country will specialize in the production of this good and trade it for other goods.

The following graphs show the production possibilities frontiers (PPFs) for Shenandoah and Congaree. Both countries produce almonds and lentils, each initially (i.e., before specialization and trade) producing 6 million pounds of almonds and 3 million pounds of lentils, as indicated by the grey stars marked with the letter A.

Shenandoah has a comparative advantage in the production of , while Congaree has a comparative advantage in the production of . Suppose that Shenandoah and Congaree specialize in the production of the goods in which each has a comparative advantage. After specialization, the two countries can produce a total of

millionpounds of lentils and

millionpounds of almonds.

Suppose that Shenandoah and Congaree agree to trade. Each country focuses its resources on producing only the good in which it has a comparative advantage. The countries decide to exchange 4 million pounds of almonds for 4 million pounds of lentils. This ratio of goods is known as the price of tradebetween Shenandoah and Congaree.

The following graph shows the same PPF for Shenandoah as before, as well as its initial consumption at point A. Place a black point (plus symbol) on the graph to indicate Shenandoah's consumption after trade.

Note: Dashed drop lines will automatically extend to both axes.

The following graph shows the same PPF for Congaree as before, as well as its initial consumption at point A.

As you did for Shenandoah, place a black point (plus symbol) on the following graph to indicate Congaree's consumption after trade.
