Production Possibilities Curve as a model of a country's economy발음듣기

다른 번역문 등록

[Instructor] Let's say that we have some country, let's call it Utenslandia, that can only produce one of two goods or some combination of them.발음듣기

다른 번역문 등록

So it can produces forks, or it could produce spoons.발음듣기

다른 번역문 등록

And so this axis is the quantity forks this axis is the quantity of spoons and let's say that if it puts all of its energy into forks, well it would produce that many forks and no spoons。발음듣기

And but then if tried to focus some of its energy, some of its resources on spoons well then it would produce fewer forks.발음듣기

다른 번역문 등록

And then the more spoons it produces it will produce fewer and fewer forks all the way to the point that if it only focused on spoons well it could produce that many but then it would produce no forks.발음듣기

What this curve is, and we touched on it on other videos, this is the production possibilities curve for our country of Utenslandia that makes utensils and obviously, most countries are much more complex they don't only produce some combination of two things but this helps us, this is a nice model for understanding what countries might be capable of.발음듣기

Now one way to understand this production possibilities curve is it shows what can be efficiently produced by this country.발음듣기

다른 번역문 등록

If it efficiently utilized all of its resources then it will produce some combination of forks and spoons that sit on the production possibilities curve.발음듣기

다른 번역문 등록

So this point right over here this combination of spoons which would be that many spoons and that many forks this combination over here, this would be efficient.발음듣기

다른 번역문 등록

That point x would be an efficient production for Utenslandia.발음듣기

다른 번역문 등록

So at this point right over here, let's call that point y.발음듣기

다른 번역문 등록

Now what happens if Utenslandia goes into some type of recession.발음듣기

다른 번역문 등록

For whatever reason, it's not able to use its resources as efficiently.발음듣기

다른 번역문 등록

And we're talking about resources we're talking about land, we're talking about maybe its factories, we're talking about the materials it has, maybe its labor well on that situation.발음듣기

다른 번역문 등록

Let's say it was operating efficiently here but then the recession happens and so it then it operates right over here.발음듣기

다른 번역문 등록

Let's call this point right over here z this would be an inefficient use of its resources sitting behind the production possibilities curve.발음듣기

다른 번역문 등록

So this is inefficient, just like that.발음듣기

다른 번역문 등록

And so one question you might have is well what about points that are beyond the production possibilities curve like point, let's just call that point a right over there.발음듣기

다른 번역문 등록

What about that point?발음듣기

다른 번역문 등록

Well, unless you have more inputs unless you have more land, more capital more labor, if you don't change the resources here this is actually going to be an unattainable point for Utenslandia.발음듣기

다른 번역문 등록

But let's say you really wanna reach it how can that happen?발음듣기

다른 번역문 등록

Well, you can actually have investment or you could have more land or more labor.발음듣기

다른 번역문 등록

So let's think about that scenario.발음듣기

다른 번역문 등록

So let me draw the two axes.발음듣기

다른 번역문 등록

So that's my fork axis, that's the quantity of forks that Utenslandia will produce in the year.발음듣기

다른 번역문 등록

This will be the spoon axis, right over there.발음듣기

다른 번역문 등록

And let's draw our original production possibilities curve.발음듣기

다른 번역문 등록

So I'll try to make it look pretty similar to what we had before.발음듣기

다른 번역문 등록

So that's our original production possibilities curve.발음듣기

다른 번역문 등록

Another way of thinking about it is it's showing the trade off between producing forks and spoons.발음듣기

다른 번역문 등록

You can actually think about what is the opportunity cost of producing an incremental spoon in terms of forks.발음듣기

다른 번역문 등록

How many forks do you have to trade off because remember, there's scarcity at play.발음듣기

다른 번역문 등록

You don't have an infinite amount of metal to produce things with, an infinite amount of labor an infinite amount of factories.발음듣기

다른 번역문 등록

But let's say Utenslandia, they are able to get some more land on which to build factories maybe they build some more factories so capital goes up, maybe some people migrate to Utenslandia.발음듣기

다른 번역문 등록

So in that situation, you would have growth and your production possibilities curve would actually shift outward.발음듣기

다른 번역문 등록

So here, we are showing let me make it a little bit we are showing a situation right over here this is still a production possibilities curve but we're showing what happens when you have growth.발음듣기

다른 번역문 등록

And once again, what are the drivers of growth?발음듣기

다른 번역문 등록

Well this could be the amount of land that you have goes up.발음듣기

다른 번역문 등록

The amount of capital that you have goes up.발음듣기

다른 번역문 등록

Capital could be things like factories it could be machinery you could have people, more people are able to help produce the spoons or forks.발음듣기

다른 번역문 등록

You could just have better technology for producing spoons and forks.발음듣기

다른 번역문 등록

Sometimes people will even talk about entrepreneurial spirit that people are able to figure out better ways of combining these resources so that you could produce more spoons or forks.발음듣기

다른 번역문 등록

But let's imagine now the other scenario.발음듣기

다른 번역문 등록

Let's imagine a scenario where Utenslandia gets into a war with Platelandia.발음듣기

다른 번역문 등록

And Platelandia sends their bombers in and starts destroying some of the factories of Utenslandia and so what will happen in that situation?발음듣기

다른 번역문 등록

So before the war, this is that production possibilities curve for Utenslandia.발음듣기

다른 번역문 등록

But now, because of the war, maybe Platelandia is able to take some land from Utenslandia maybe it's able to destroy some of the factories and other forms of capital maybe people flee Utenslandia so there's less labor.발음듣기

다른 번역문 등록

And maybe for whatever reason they can support less technology or they forget how to use some of their technology 'cause the war is so long and protracted.발음듣기

다른 번역문 등록

Well in that situation, your PPC, you would see contraction.발음듣기

다른 번역문 등록

And contraction, I could depict it let me shift my PPC, my production possibilities curve inward just like this.발음듣기

다른 번역문 등록

So this is a situation where we are seeing contraction.발음듣기

다른 번역문 등록

So big picture here, your production possibilities curve is exactly what it says it is.발음듣기

다른 번역문 등록

It shows what can a, what is the potential combination of, in this case, goods that this nation can produce and if you're sitting on the curve it shows that that nation, that country is efficiently using its resources.발음듣기

다른 번역문 등록

If you're sitting within the curve it's inefficiently using its resources.발음듣기

다른 번역문 등록

And if you're on the right of the curve or beyond the curve, well that's a situation where if you don't change the inputs all else equal, this would actually be unattainable.발음듣기

다른 번역문 등록

The way that you actually do attain, get to points beyond the curve, is by shifting the curve itself.발음듣기

다른 번역문 등록

By having more land, more capital, more labor or more technology which we see in this middle scenario.발음듣기
