A country produces 100 units of wheat using the same resources that another country produces 80 units of wheat. Additionally, the first country can produce 50 units of rice while the second can produce 30 units of rice. Based on this information, classify the countries in terms of absolute and comparative advantage.

Absolute advantage refers to the ability of a country to produce more of a good using the same resources than another country. In this case, the first country has an absolute advantage in both wheat and rice because it produces 100 units of wheat compared to 80 units from the second country, and 50 units of rice compared to 30 units. Comparative advantage, on the other hand, looks at the opportunity cost of producing goods. The first country gives up fewer units of rice to produce each unit of wheat compared to the second country, which makes it more efficient in wheat production. Therefore, the first country has an absolute advantage in both goods, while the second country has a comparative advantage in rice production because it sacrifices fewer wheat units to produce rice than the first country does.
