Country A can produce either 10 units of wine or 5 units of cheese using the same resources. Country B can produce either 6 units of wine or 2 units of cheese. Which country has a comparative advantage in cheese production?

To find out which country has a comparative advantage in cheese production, we need to look at how much each country gives up to produce cheese instead of wine. Country A can make 10 units of wine or 5 units of cheese, so for every unit of cheese it produces, it gives up 2 units of wine. Country B can make 6 units of wine or 2 units of cheese, meaning it gives up 3 units of wine for each unit of cheese. Since Country A gives up fewer units of wine to produce cheese compared to Country B, it has the comparative advantage in cheese production. Therefore, Country A should focus on making cheese, while Country B should focus on wine.
