Answer:
The best deal would be option B) that is
Lillytonia sells 1/4 bushels of wheat to Pam land and gets 1 DVD player in return.
Explanation:
STEP 1
The output of DVD per unit of labor for Pamland = 150.
The output of Bushels of wheat per unit of labor for Pamland= 300.
The output of DVD per unit of labor for Lillytonia = 200.
The output of Bushels of wheat per unit of labor for Lillytonia= 600.
STEP 2
To calculate the comparative advantage, we use the following formula:
Comparative Advantage = DVD Output / Wheat Output
STEP 3
In Pamland, the opportunity cost, or the comparative advantage, of DVD is
300 / 150 = 2 bushels of wheat.
The opportunity cost of wheat in Pamland is 120/ 300 = 0.5 DVDs.
In Lillytonia the opportunity cost, or comparative advantage, of DVD is 600/200 = 3 bushels of wheat, while
The opportunity cost of wheat in Lillytonia is 200/600 = 1/3 or 0.33333 DVDs
STEP 4
As is clear from the calculations, Pamland should produce more wheat because it has the lower opportunity cost during production 2 against 3 for Lillytonia. Conversly, Lillytonia has the lowest opportunity cost for the production of DVD clocking 1/3 against a higher 1/2 for Pamland.
The countries should therefore trade in such a way that Pamlan is selling it's Wheat while Lillytonia is selling it's DVDs.
STEP 5
Given that Pamland's 2 bushels of wheat will cost it 0.5 DVDs, 4 bushels will thus cost it 1 DVD. It is impracticable (in any case) to have 1/2 of a DVD player.
