Suppose that greece and switzerland both produce oil and shoes. greece's opportunity cost of producing a pair of shoes is 4 barren of oil while switzerland's opportunity cost of producing a pair of shoes is 10 barrels of oil.
by comparing the opportunity cost of producing shoes in the two countries, you can tell that greece has a comparative advantage in the production of shoes and switzerland has a comparative advantage in the production of oil.
suppose that greece and switzerland consider trading shoes and oil with each other. greece can gain from specialization and trade as long as it receives more than 4 barrels of oil for each pair of shoes it exports to switzerland. similarly, switzerland can gain from trade as long as it receives more than 1 pair of shoes for each barrel of oil it exports to greece.

which of the following prices of trade (that is, the price of shoes in terms of oil) would allow both switzerland and greece to gain from trade? check all that apply.

a. 1 barrel of oil per pair of shoes
b. 2 barrels of oil per pair of shoes
c. 8 barrels of oil per pair of shoes
d. 18 barrels of oil per pair of shoes

8 barrels of oils per pair of shoe

Explanation:Greece and swizerland will need an average price by which they can both gain from trade.To ascertain the average price is by adding the 4 barrels of oil which Greece can forfeit and the 10 barrels of oil which Switzerland could also forfeit if it were into producing shoes.10+ 4 = 14/2 which almost 8 barrels to be given in exchange in other ensure a fair trade between both trading partners.

answer; by looking at total product,marginal product,and changes in both after changes in inputs

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
