- Analyze the opportunity costs for both countries: Country A has an opportunity cost of \(0.5\) for petroleum and \(2\) for seafood, while Country B has an opportunity cost of \(1\) for both.
- Compare the opportunity costs for petroleum: Country A's cost (\(0.5\)) is lower than Country B's (\(1\)), so Country A specializes in petroleum.
- Compare the opportunity costs for seafood: Country B's cost (\(1\)) is lower than Country A's (\(2\)), so Country B specializes in seafood.
- Final answer: Country A specializes in petroleum, Country B specializes in seafood.
Explanation
- Analysis of Opportunity Costs and Comparative Advantage
We are tasked with determining the specialization for two countries, Country A and Country B, in the production of petroleum and seafood, based on the principle of comparative advantage. We are given the following opportunity costs (OC) for production:
- Country A:
- 1 unit of Petroleum costs \(0.5\) units of Seafood.
- 1 unit of Seafood costs \(2\) units of Petroleum.
- Country B:
- 1 unit of Petroleum costs \(1\) unit of Seafood.
- 1 unit of Seafood costs \(1\) unit of Petroleum.
Comparative advantage suggests that a country should specialize in the production of a good for which its opportunity cost is lower than that of the other country.
- Determining Specialization for Petroleum
To determine which country should specialize in petroleum, we compare the opportunity costs of producing one unit of petroleum for both countries:
- The opportunity cost of 1 unit of Petroleum for Country A is \(0.5\) units of Seafood.
- The opportunity cost of 1 unit of Petroleum for Country B is \(1\) unit of Seafood.
Since \(0.5 < 1\), Country A has a lower opportunity cost for producing petroleum. Therefore, Country A possesses a comparative advantage in the production of petroleum.
- Determining Specialization for Seafood
To determine which country should specialize in seafood, we compare the opportunity costs of producing one unit of seafood for both countries:
- The opportunity cost of 1 unit of Seafood for Country A is \(2\) units of Petroleum.
- The opportunity cost of 1 unit of Seafood for Country B is \(1\) unit of Petroleum.
Since \(1 < 2\), Country B has a lower opportunity cost for producing seafood. Therefore, Country B possesses a comparative advantage in the production of seafood.
- Conclusion
Based on the analysis of comparative advantage:
- Country A should specialize in the production of petroleum because it has a lower opportunity cost (\(0.5 < 1\)).
- Country B should specialize in the production of seafood because it has a lower opportunity cost (\(1 < 2\)).
Thus, the final results are:
According to opportunity costs, Country A should specialize in petroleum.
According to opportunity costs, Country B should specialize in seafood.
Examples
Comparative advantage is a fundamental concept in global trade. For example, if a country has a climate perfect for growing coffee but poor for manufacturing electronics, it will likely have a lower opportunity cost for coffee production. Conversely, a country with high-tech infrastructure and a skilled engineering workforce will likely have a lower opportunity cost for electronics production. By specializing in their respective fields of comparative advantage and trading, both countries can consume more than they could produce alone, leading to higher overall welfare.
