2. Comparative Advantage: This describes the advantage when a business, individual or even a nation is able to maunfacture a good or offer a service at an opportunity cost that is lower than other competitors in the business. It simply means the ability to produce a good or service at a cost cheaper than one's competitors.
Step 1: By comparing the opportunity cost of producing wine in the two countries, you can tell that Spain (ability to produce a bottle for 4 pounds of fish as compard to 10 pounds by Sweden) has a comparative advantage in the production of wine
Also Comparing the opportunity cost of wine as well, Sweden has the comparative advantage in the production of fish (10 pounds of fish as compared to 3 pounds that can be produced by Spain for a bottle of while).
Step 2: The Trading of wine and fish between Spain and Sweden
a) as long as Spain is able to get more than 4 pounds of fish (what it can produce) for every exported bottle of wine, then it can gain from a trade with Sweden.
b) Also , as long as Sweden is able to receive more than 1/10 bottles of wine for each pound of fish it exports to Spain, it can gain from the specialization and trade.
Step 3: Prices of trade (of wine in terms of fish) will allow both Sweden and Spain gain from Trade.
The correct answer is 9 Pounds of Fish per bottle of Wine. This is correct because Spain can get more than the minimum 4 pounds of fish it needs and Sweden can receive more than 1/10 the bottles of wine it needs to make a gain.
