Mini video: Absolute advantage and comparative advantage (1)
Summary
TLDRIn this educational video, Iris Franz explains the concepts of absolute and comparative advantage in trade theory. She uses an example with the USA and China producing ibuprofen and shoes to illustrate absolute advantage, where the US is more efficient in both products. Comparative advantage is then explored through calculating opportunity costs, showing the US has a comparative advantage in ibuprofen production due to a lower opportunity cost. The video concludes by hinting at China's comparative advantage in shoe production, leaving the calculation as an exercise for the viewers.
Takeaways
- š The lecture is about absolute and comparative advantage in international trade theory.
- š Absolute advantage is defined as the ability to produce a good more efficiently with the same resources.
- š Comparative advantage is the ability to produce a good at a lower opportunity cost compared to another.
- šŗšøšØš³ The example uses the USA and China as two countries and ibuprofen and shoes as two goods for illustration.
- š The USA has an absolute advantage in producing ibuprofen, as it can produce 10 bottles per labor hour compared to China's 2 bottles.
- š The USA also has an absolute advantage in producing shoes, with 5 pairs per labor hour versus China's 2 pairs.
- š§® To calculate comparative advantage, one must determine the opportunity cost of producing one good in terms of the other.
- š The opportunity cost is calculated by treating one good as a 'currency' and determining how much of the other good is sacrificed to produce it.
- š The USA has a comparative advantage in ibuprofen production because the opportunity cost is 0.5 pairs of shoes compared to 1 pair in China.

Outlines
š Understanding Absolute and Comparative Advantage
In this educational video, Iris Franz introduces the concepts of absolute and comparative advantage in the context of international trade. Absolute advantage is defined as the ability to produce a good more efficiently, meaning a country can produce more of a good with the same resources. Comparative advantage, on the other hand, is the ability to produce a good at a lower opportunity cost. The video uses the example of the USA and China producing ibuprofen and shoes to illustrate these concepts. The USA can produce 10 bottles of ibuprofen or 5 pairs of shoes in one labor hour, while China can produce 2 bottles of ibuprofen or 2 pairs of shoes in the same time. The USA is more efficient in producing both goods, indicating an absolute advantage. The video then delves into calculating opportunity costs to determine comparative advantage, which is more complex but crucial for understanding trade benefits.
š Opportunity Cost and Comparative Advantage
This segment of the video focuses on calculating opportunity costs to determine comparative advantage. The opportunity cost is the amount of one good that must be foregone to produce another. For the USA, the opportunity cost of producing one bottle of ibuprofen is 0.5 pairs of shoes, calculated by treating shoes as a 'currency' and dividing the number of shoes (5) by the number of ibuprofen bottles (10). In contrast, China's opportunity cost for one bottle of ibuprofen is one pair of shoes, as they can produce 2 bottles for 2 pairs of shoes. This comparison shows the USA has a lower opportunity cost for ibuprofen, indicating a comparative advantage. The video concludes by asserting that the USA has a comparative advantage in producing ibuprofen and hints that China has a comparative advantage in shoe production, encouraging viewers to calculate this as homework.

Transcripts
Hello everyone my name is Iris Franz and todayĀ we are going to talk about absolute advantage andĀ Ā
comparative advantage. So the difference betweenĀ the two is this: the definition of absoluteĀ Ā
advantage is the ability to produce a good moreĀ efficiently. So with the same resource you canĀ Ā
produce more than you're more efficient. AndĀ the definition of comparative advantage is this:Ā Ā
the ability to produce a good at a lowerĀ opportunity cost. So once you realize theĀ Ā
difference between the two definition you will notĀ get them confused. So we're going to start with anĀ Ā
example so we have two countries the USA and ChinaĀ and we have only two goods: ibuprofen so that'sĀ Ā
a kind of painkiller measured in bottles, and theĀ other good is shoes. So supposing one labor hour,Ā Ā
the US can produce either 10 bottles of ibuprofenĀ or 5 pairs of shoes. And in the same labor ourĀ Ā
China can produce either two bottles of ibuprofenĀ or two pairs of shoes so the first question isĀ Ā
which country has an absolute advantage in theĀ production of ibuprofen? So we see which countryĀ Ā
can produce ibuprofen more efficiently, thenĀ that country has an absolute advantage in theĀ Ā
production of ibuprofen. So we can see in oneĀ labor-hour the US can produce ten bottles ofĀ Ā
ibuprofen whereas China can only produce twoĀ bottles of ibuprofen so 10 is bigger in two;Ā Ā
we say the US has an absolute advantage in theĀ production of ibuprofen. So what about shoes soĀ Ā
that's write down USA here first. What about shoesĀ you can see in one labor-hour the US can produceĀ Ā
five pairs of shoes whereas China can produceĀ only two pairs of shoes so five is bigger thanĀ Ā
two so we know that US has an absolute advantageĀ in the production of shoes. So that one is stillĀ Ā
relatively straightforward. What is a littleĀ more complicated will be comparative advantage.Ā Ā
So suppose the next question ask you which countryĀ has a comparative advantage in the production ofĀ Ā
ibuprofen? Now we go back to our definition: YouĀ have a comparative advantage if you are able toĀ Ā
produce a good and a lower opportunity cost. So toĀ answer that question we will have to calculate theĀ Ā
opportunity cost of ibuprofen production of bothĀ USA and China. So what is the opportunity cost ofĀ Ā
a bottle of ibuprofen in terms of shoes in theĀ US? Now most students find it more challengingĀ Ā
because they don't know if you should divideĀ 10 by 5 or divide 5 by 10. So here's a key:Ā Ā
if you have two Goods A and B, and you're tryingĀ to calculate the opportunity cost of good A thenĀ Ā
you're going to treat good B as a currency.Ā Here's an example we're trying to calculateĀ Ā
the opportunity cost of ibuprofen so we're goingĀ to treat shoes as currency, okay? So suppose youĀ Ā
go to a store and you want to buy ibuprofen,Ā right? We want to know the cost of ibuprofen,Ā Ā
so you ask the owner of the shop: what is the costĀ of ibuprofen in your shop? And the owner tells youĀ Ā
the cost of ten bottles of ibuprofen is fiveĀ dollars. Look, you treat that as a currency soĀ Ā
after listening to that, you say, hey 10 bottlesĀ of ibuprofen cost five dollars what is the costĀ Ā
of one bottle of ibuprofen now it's very clearĀ we divide five by ten right? Because five is theĀ Ā
currency. So here is the same, the opportunityĀ cost of ibuprofen you know is 5 divided by 10 inĀ Ā
the US and that gives you a half now don't forgetĀ that it is actually a pair of shoes so you put aĀ Ā
half pair of shoes. So the opportunity cost ofĀ one bottle of ibuprofen a half pair of shoesĀ Ā
in the US. What about China so it's the same youĀ treat the other good as currency suppose you'reĀ Ā
in China and you go to the store you want to buyĀ a bottle of ibuprofen and they tell you that costĀ Ā
of two bottles of ibuprofen is two dollars so youĀ divide two by two to get the cost of ibuprofen soĀ Ā
here in China is two divided by two and you getĀ one don't forget to change your currency back toĀ Ā
your shoes so the opportunity cost of ibuprofenĀ in China is one pair of shoes. Now it's obviousĀ Ā
that a half is lower than one, so now it's clearĀ which country has a comparative advantage in theĀ Ā
production of ibuprofen? That will be the US.Ā Here: US has a comparative advantage in theĀ Ā
production of ibuprofen because the opportunityĀ cost of the production of ibuprofen is lower:Ā Ā
A half pair of shoes compared to one pair ofĀ shoes in China. So what about the comparativeĀ Ā
advantage in the production of shoes? I'm goingĀ to the answer is China but I want you to pleaseĀ Ā
leave this as a homework so in order to tellĀ which country has a comparative advantage inĀ Ā
the production of shoes, again you have toĀ calculate opportunity cost right? And I willĀ Ā
just tell you the answer: the opportunity costĀ of shoes in US is two bottles of ibuprofen andĀ Ā
in China is one bottle ibuprofen and thatĀ is lower than that and I want you to do theĀ Ā
calculation yourself as a homework. So thank youĀ for watching, and good luck with your studying.
