Sorry about barrels of oil and cheese.
00:05
So i'm going to call the barrels of oil b, and i'm going to call the cheese, right? and we have two countries.
00:14
And we're told something about their opportunity cost.
00:17
For greece, the opportunity cost of producing one cheese is equal to four barrels of oil.
00:25
But for sweden, the opportunity cost of one cheese is they have to give up 10 barrels of oil, right? i'm setting these things equal because they have equal costs, right? either country can choose to produce one or the other at the same cost.
00:41
So here, greece has comparative advantage in cheese.
00:52
And it has comparative advantage in cheese because it has to give up less oil to get the cheese, right? sweeten has to give up more oil.
01:00
Grease has to give up more barrels of oil.
01:03
So greece has the comparative advantage in cheese.
01:05
But if we flip these, right, i'm going to divide both of them by four.
01:10
I get 0 .25c equals 1b, first greece.
01:15
And for sweden, i get 0 .1c is equal to 1b.
01:20
So sweden has comparative advantage in oil, right? because for sweden, to produce one barrel of oil, it gives up less cheese.
01:30
It gives up 0 .1 cheese as opposed to greece, which would have to give up 0 .5 cheese.
01:34
So the pattern of trade here between greece and sweden is that greece is going to send cheese to sweden because greece is good at cheese and sweden will return oil to greece because sweden is good at oil, right? so the key things are here is about the terms of trade, which are going to be mutually acceptable to both of these countries, right? if we're thinking about selling cheese, grease needs greater than four barrels per cheese...
