Gotta love when your instructor sends you to these videos to explain the topic. Pay tens of thousands of dollars for a college education and they send you to RUclips to learn it.
My exact current situation🤣
currently watching this for a discussion board
Lmao
Is that all they did or was that to supplement what they had already given you?
@@karenmay08probably a lot of videos then a test
how does this guy literally know every subject lol
He's a genius he'd get paid a lot of money doing online lectures I'd pay to watch the knowledge flow out of him
He's an MIT graduate. He propably didn't spend his weekends smoking weed or getting drunk. People like this don't like wasting time like I"m doing answering your question.
@@improvmaniac bit unnecessary lol but you do you
All these subjects are covered in 1st year of engineering .
Proud to say he is a Bangladeshi :)
...why cant regular school... be this simple?? I've been stressing my macroeconomics class... ALL... SEMESTER... and in just 20 minutes with Sal's videos... I can ace my quiz... wow... just wow!
because in regular school your with other people....here its just you ...as Aristotle said..the best classroom size is one
Mr Petester z Well said!
I swear its his voice, style of speaking with ace graphics. idk, but kahn academy saved my grade on multiple occasions.
Same here. I had to go to Khan videos to quit banging my head against the wall for something that is so simple when explained correctly.
I'm doing online Macro and I had to come here. Normally I excel in independent study.

Opportunity cost is the highest valued option forgone or the best alternative. If you explain a topic too simple, every student would become kindergarten pupils. You think that you understand, but don't know how to answer the question.
This man is totally INSANE...!
He knows EVERYTHING
On God 💀

Lol imagine the opportunity costs for folks who aren't watching this.
I was curious as to what the marginal utility was at E, without assuming linearity.
For those of you who are also curious here's how I worked it out:
I noticed that the the sequence of berries had a constant second derivative of -20 i.e. the amount that the production of berries decreased by for each rabbit produced was increasing each time by 20. This is characteristic of a quadratic function and can be proved using integration.
I then worked out the coefficients of the quadratic by substituting in the known points in the video. This gives B=f(R)=-10R^2-10R+300, differentiating this gives the marginal utility: f'(R)=-20R-10. So at point E the marginal utility is f'(1)=-30, in terms of berries this gives 1/30.
Thank god for Khan!!! Im so stress out due to this class!! I was going to drop out! But thanks for saving me khan!!!!!
thank sal for Khan..... god did nothing here
The lesson looks very appealing when you switch it to 720p Full-screen,TRY IT !
This academy is an incredible gift.
Instead of 'marginal cost' (which usually has another meaning), I suggest 'marginal opportunity cost'.
RUclips is literally the best college in the world.... and it's free.
Two microeconomic teachers could not explain this to me.
Kidding me?
These videos are very beneficial for my A level course. Thanks Sal
기회비용이라는 말을 삶을 살면서 정말로 많이 들어본 것 같습니다. 하지만 경제학에서 마주하게 된 것은 처음입니다. 실생활적인 예시를 들어서 기회비용의 개념을 이해하기 쉽게 잘 설명해주셔서 감사합니다.

I got this class called "applied resource ecnomics, its mainly micro with 1 or 2 chapters of macro. Kahn accademy W!
Love these scenarios; clear and straightforward examples make learning easy
I can learning very hard. In the classroom, the teacher does not explain and let the students to reason independently. Still, I get a pass in the Hong Kong Advanced Level Examination Economics subject in 2003. As for the Chinese History subject, the teacher gives me some tips but I do not believe. As a result, I get Fail.
it would be great if you don't split the videos, because it gets confusing. But other than that your videos are great and very helpful.(don't take this the wrong way I'm not criticising)
As someone who has a shorter attention span and needs to see that golden "small amount of time" time stamp, I appreciate the cut up :) I also appreciate that they organized the videos into playlists to keep them contiguous and I can pick up where I left off based on completed videos. Makes for better achievement progress--for me :)
Reminder to future students, there is an "introduction to economic" playlist with all the basic you needed to know about economic. It isn't in economic/finance category but in the first playlist category with no specific name
its very good explanation , the repeating of word is very good for the people like me who is not too good in english
Proud to say, humanity still is surviving and will always.
Wow starting with microeconomics now? Awesome stuff Sal, you have a great way of describing things clearly. Are you going to look at micro with calculus as well?
Awesome! Makes sense, now im feeling more prepared for my exam
THANK YOU THANK YOU THANK YOU for this video.
5th year comparison:
former 18 years old McD worker with 10K in contribution a year
total160K + 20K= 180K
former 18 years old student with B.A., career at McD corporation.
30K with zero investment (pay off student loan)
When will they catch up?
This simple factor has made complicated as hell in class rooms,thanks a lot
Thank you so much 💖🇪🇬
I'm wondering if anyone could tell me what kind of tool/software this video was using to record the screen and the sound ... thanks a lot!
it is gonna to be clased all other videos ...very interesting way to understand the microeco from khan sir ...

The resources are finite, hence we need to make the best choices. The principle of opportunity cost helps us in making the correct choices.
For instance everyone has 24 hours in a day. How do we use the next 1 hour of our time.
Extending this principle beyond money , each individual chooses that which provides the greatest value to the individual.
One person may value serving others, another making money, a third family time. This understanding of opportunity cost helps us in allocating maximum resources for what we value.
Thanks.

It's not annoying to me. That's the only thing that's helping me understand it. I have a problem understanding numbers. I had a NDE that caused left-side brain trauma due to total lack of oxygen to the brain. When you're clinically dead (NDE) oxygen loss to the brain is unavoidable.
When you are writing a sentence, you repeat each word like 1000 times till you finish with writing.. ANNOYING.., but you are very helpful, I've learned a lot from your vids. thanks
This bothered me, too, until I started hearing his echoing in the voice of The Count. "FIVE! FIVE RABBITS! AH AH AH AH AH AH AHHHH" (sound of thunder in background)
I don't know I like it lol it really drills the concept in my head
Lol "we're in the mood for more protein"XD.
Thank you very much . This Guy knows everything
this video is pretty beneficial😊
All this is according to Robb, who works with money, is an example of how it works. Robb understands these things way better than I do.
thank so mach!! for your clear and understandable lecture of these complx principles!!
@kschoe937 maybe after learning all these videos, you can ask a professor if he/she would be interested in doing some independent study on a special topic with you. now that you've watched all the vids, there might be some particular topic you can dig more in depth. that would accelerate your learning more
机会成本不可能量化, 也不可能排次序, 过往的教法把机会成本量化是错誤的, 發明utils 把机会成本量化尤其错誤, 有些老師会說, 沒有最衰, 只有更衰,
if you were to make a tv show, that PPF curve would shift to the right big time
Gracias! Me encanta la proteína!
FlexioN de nada.
writting my microeconomics exam with a not so great average but im sure ill kick buu because of khan's videos
How did you do??
THANK YOU

Is there a way to take tangents of lines like this with just raw data? Or must they always be graphed with traditional numeration?
This might sound silly, but how does this work in a real-life situation? With a business or whatnot?
I'm having trouble understand its practical application.
Complexity at its best.
love this guy
Thankyou
Great content! Thanks for uploading!
thank you so much
Your videos are excellent! Thanks bunches. :)
nice definition
I love the videos that you make!!!
Thx man ur the best
you are a God....
I am thinking, based on the average guy and the claimed backed by the U.S. Dept. of Education, that a college student made twice the amount of the minimum wage worker.
Average salary of Bachelor degree: ~ 30,000 USD
Minimum wage per annum: ~16,000
We are starting at 18 years of age. If one invest normally, in 8-10 years his contribution times two. It take at least four years after high school, to earned a bachelor degree. Those four years of education, he have no income.
Very helpful
I still confuse about opportunity cost
I read a lot about it but all of them gave me different ideas 😭
It mean the alternative I choose it to take what I want like a production but i will give up another something like a money ?
Or i have to choose between a highest-valued and another cheaper, but I don’t know what the interest i will get it ?
Wich one is right !?
Vicki Bee This is just an example to understand opportunity cost. In reality you will not really have zero berries or rabbits because you give up berries or rabbits, due to the presence of trade. For example when you give up all berries and use the time to hunt rabbits you can use the extra rabbits you get to trade for berries. You should know the world better before you made any negative comments.
how about the opportunity cost from inside the curve to along the curve??
it's negative... there's no opportunity cost, only benefit

great video
mm okay.
opp cost of 1 more rabbit is 40 berries. and the 40 berries can be thought of as the marginal cost.
but then opp cost of 20 more berries is 1 rabbit. but this is not a marginal cost because he is talking about 20 more units and not just one? in the first scenario then wasn't he talking about 40 more units and not just one?
The opportunity cost differs depending on from what scenario to what scenario. From F to D is 60 berries. From E to C is 100. In both, you catch 2 more rabbits.
You may have to gather data for each hour of the day gathering only berries, and gathering only rabbits, to see what hours of the day are best for gathering each.
Another way of saying “the opportunity cost of 20 berries is 1 rabbit” is to say “as you gain 20 berries than you would in another scenario, you lose the rabbit you would have gained in that other scenario.”
It’s interesting that it’s worded as a “loss,” or a “cost,” when you really don’t get it to begin with. It’s a lost opportunity, yes-“you lost the opportunity to get another thing”-but it’s rather a gain fore-gone.
Why now, Sal? Why now? ;_; I had to do the remedial on this chapter last semester...
You are awesome Khan, but in the scenario you described where all things were equal with Rabbits and Berries, would it not be never worth it to go after a rabbit, because you do not befit from increased caloric and nutrient consumption?
You got it wrong bro, it equal mean the hunter use the same hunting gathering method in each scenario. The value of the strawberries and the rabbit aren't the same, a rabbit seem to be significantly more valuable than a berry though
THAT MATH AMAZING KIDS AT SCHOOL
Dear Khan Academy, is the production possibilities frontier identical to production possibility curve?
the production possibility curve is also known as the production possibility frontier!
how come these video's aren't on the khanacademy site?
Yes, it's the same thing. :)
woohoo khan academy doesn't suck
Psst i was the first to like.
Can't we find the curve using lagrange interpolation and differentiate? I come from a math background so this was my first instinct :P
yes
nicee
That's what I am: a vegetarian. But you don't give up protein to be a vegetarian. You give up meat and replace it with protein from other sources. Like sunflower seeds, pasta, rice and peanuts. And eggs. I'm not vegan.
tbh i was wondering more of a strawberry and dogs not fr rabbits and berries but ig
O lawd, I'm in trouble. Help me these next 5 weeks!
The lower you are on the curve, the higher your opportunity cost
大埔公路出九龍慢車, 龍尾在污水処理厂,
Now all of a sudden we're in the mood for protein XD
damn couldnt have came out 2 weeks ago before my micro exam xD
so marginal cost is just the number of one of the opportunity cost?
Some might say, we were in a VERY berry mood. ----end nerd joke lol
At 4.40 you mean one twentieth of a rabbit, not a berry.

Don't hurt rabbits. Can't we do a PPC that doesn't involve violence to animals?
Profesor miss
Opportunity-depreciation isn't real either.
And it's boring as hell.
I wanted to be excited about it with every fiber of my being, but I failed to do that.
I'm too much like Charles Dickens about these things and don't believe that if you're going to claim corp. really are "people" that it should be devoid of compassion. PEOPLE have compassion. I've never seen a corp. have that, and it's obvious by this that cold, steely logic is all this will ever be.
again with the rabbit fractions!?!? I DONT KNOW WHAT 1/20th OF A RABBIT IS.
This man no everything LOL Dead
