Final answer:
The trade barriers experienced by Saudi Arabia relate to the opportunity cost of domestic production versus international trade. Saudi Arabia will benefit by importing corn because producing it domestically requires giving up a higher amount of oil. Thus, efficient trade can allow the country to enjoy more goods than its domestic production capacities alone.
Step-by-step explanation:
The question asks about the trade barriers experienced by Saudi Arabia. In the context of the Saudi Arabian economy, after specializing, there are certain advantages that need to be considered. When discussing trade benefits, it's essential to look at the concept of opportunity cost. The Production Possibilities Frontier (PPF) illustrates the trade-offs between two choices. For Saudi Arabia, if there's no international trade, to increase domestic production of corn, they must sacrifice a substantial amount of another good, which is oil in this case.
According to the scenario provided, Saudi Arabia stands to gain by importing at least 10 bushels of corn and exporting less than 60 barrels of oil. The reason for this is that the opportunity cost of producing corn domestically is high--four barrels of oil for one bushel of corn. Therefore, if Saudi Arabia can find a trade deal where they give up less than four barrels of oil for every bushel of corn they receive, or conversely, receive more than one bushel for every four barrels of oil they trade away, they will benefit from trade.
