Solution
1. A country has a comparative advantage in producing that good if the opportunity cost of producing that good is lower in that country as compared to another country.
Bintu:
8 cups = 2 bowls
1 cup = 2/8 = 1/4 = 0.25 bowls
1 bowl = 8/2 = 4 cups
Opportunity cost of producing 1 cup is 0.25 bowls and 1 bowl is 4 cups.
Juba:
6 cups = 4 bowls
1 cup = 4/6 = 0.67 bowls
1 bowl = 6/4 = 1.5 cups
Opportunity cost of producing 1 cup is 0.67 bowls and 1 bowl is 1.5 cups.
Opportunity cost of producing 1 cup is lower when it is produced by Bintu. So, Bintu has comparative advantage in the production of cups. On the other hand, Juba has comparative advantage in the production of bowls.
Therefore, answer is b) cups and Juba has comparative advantage in the production of bowls.
