Country a and b are producers of cars and computers.
00:04
In country a, it takes 20 minutes to produce a car and 20 minutes to produce a computer.
00:19
In country b, it takes 40 minutes to produce a car and 10 minutes to produce a computer.
00:30
Which country has absolute advantage in producing each good? so who can produce this with the least amount of time? so we could see that a has the absolute advantage in cars.
00:43
It could produce it in 20 minutes versus 40.
00:46
B has absolute advantage in computers.
00:49
It could produce it in 10 minutes versus 20.
01:02
What are the opportunity costs to produce the goods in each country? and which has the comparative advantage? so for a, it takes 20 minutes to either make a car or computer.
01:22
So the opportunity cost of one car or one computer is one car.
01:28
To produce one computer, we need to give up the time that we could use to produce one car.
01:36
So the opportunity cost is one car.
01:39
For b, it takes 40 minutes to produce a car.
01:45
It takes 10 minutes to produce a computer.
01:47
So in the time it takes to produce one car, we can make four computers.
02:04
So the opportunity cost to produce one computer is 0 .25 cars.
02:09
To produce one car, we have to give up four computers.
02:27
So who has comparative advantage? so who can produce at the lowest opportunity cost? so to produce one computer, we give up 0 .25 cars versus one car.
02:42
So b has comparative advantage in computers.
02:46
It could produce it at the lower opportunity cost.
02:50
It gives up less cars to produce.
02:53
So to get one car, we give up four computers in b and one computer in a.
03:01
So a gives up less computers to produce the car.
03:04
So it's comparative advantage in car for a...
