Hi, everyone.
00:01
So this is problem five from chapter three.
00:04
So this question gave us like the cost of producing aircraft and shirts in terms of two countries, united states and china.
00:21
And let us to decide what kind of, what goods should the united states and china to export? right? so we need to know what property of the goods that should be export.
00:39
So if the country decided to export their productions, they should export the production which has the comparative advantages against to other country, right? or in other words, it should have the lower opportunity cost.
00:59
So it's break down to like two steps.
01:03
First, we need to calculate opportunity costs for producing one aircraft and one shirts in two countries, china and us.
01:12
And then we decided in which country producing one aircraft has lower alternative costs, which means that country should export the aircraft.
01:27
Right? so let's do the calculation.
01:31
And we know that for china, it takes china for 40 ,000 hours to produce one aircraft and four hours to produce one shirt.
01:45
So the so the opportunity cost of producing one aircraft for china is 10 ,000, right? so why is 10 ,000? so i better give the first rule.
02:01
Because we know the opportunity because you can use, you know, in order to produce the aircraft...
