Final answer:
Tunisia has the absolute advantage in producing tomatoes, as it requires only one hour to harvest each, while France holds the absolute advantage in producing green beans since it takes two hours compared to Tunisia's four hours for each.
Step-by-step explanation:
Looking at France and Tunisia's productivity in harvesting green beans and tomatoes, we can determine which country has the absolute advantage in the production of each good. To have an absolute advantage, a country must be able to produce a good using fewer resources than another country.
In France, it takes two hours to harvest green beans and also two hours to harvest a tomato. In contrast, Tunisian workers need only one hour to harvest a tomato but four hours to harvest green beans. Given that each worker in both countries works 40 hours a week, we can calculate the maximum output for each good in each country.
For tomatoes, Tunisia has the absolute advantage because it can produce 40 tomatoes (1 hour per tomato multiplied by 40 hours) in a week, whereas France can produce only 20 tomatoes in the same time (2 hours per tomato multiplied by 40 hours). In the case of green beans, France has the absolute advantage as it can harvest 20 green beans in 40 hours (2 hours per green bean) while Tunisia can harvest only 10 green beans (4 hours per green bean multiplied by 40 hours).
