I cannot wait to be rich and donate money to this channel !!!
Imaginary economics isn't going to make you rich lol.
@@bunchberry_ so true. The concept of 'utility' is completely rubbish. Ideology has infected economics unfortunately...
@@landcruiserfan4206 I’m currently learning this right now - I had a feeling it was useless. What aspects of economics are worthwhile? Macro economics?
The only thing you'll be rich of are tears because you realized that life ain't handing out free money

How's it possible that the video is one year old and your comment is 6...
@@mamtapandey9504 Video is over 6 years old. Khan academy just changes the title to make the date more recent. So more people can find it
Waiting for you dear🤣
It's been 7 years, can't remember what an indifference curve is 😂 can't say I've ever used it
What did Khan study at college?
A big thank to you SAL! What my teacher couldn't teach in 2 hrs, u taught us in 10 minutes:)
It is different.
Are you sure that Sal didn´t prime your learning and Khan, when explaining in a slightly different way made you understand?
I’m taking this for a Master’s degree and this video is better than anything I’ve received in three weeks.
These videos are much better than anything I have been taught at University.
this channel is what keeps me from dropping my econ minor!!! watched this before class and understood everything!!! thanks!!!
Crystal clear. Thank you Sal. I do not know how much knowledge you have in your mind.
What microphone are you using?
this is awesome, thanks a lot for the help!!!!
Thank you for your effort and clear explanation.
The man teaching is too good at his teaching.. Plz. Keep it up 👍👍👍
Khan. You sir. Are a Legend. Seriously
great lesson!!!
You’re a life savor. Thank you 😊
this was absolutely amazing
great and simple explanation! Thanks.
Great Video! Thank you
Thank you good lecture.. keep up the good work
comments from 6 years ago but video was “uploaded” today
Aliens have taken control over time travel!

*SYNTAX ERROR*
why is that? what happened??

awesome crystal clear vid! thankss
Thanks! I've been referring to your videos for my engineering economics course. I've found them very useful.
To note as difference and it is just graphical to realise...
Tha'ts so well explained .Thank ynou
Fantastic explanation.
... this is really good...
How is it that this guy possesses knowledge in every field?
thank you soooo much
Thank you khan academy you are the best
Yoh the best Summary ever u the Best 🥺
Thanks Google for Making UA-cam
and Thanks Ambani for cheaper rate of Internet in India
and Thanks Khan Academy
Very helpful
Thank you!!!
Great❤
Merci beaucop!
Great stuff
Thank you

YOU ARE A GIFT....!!!
you're amazing sirrrrrr
Thank you sir

preferences are represented by the utility function U( represented by the utility function A. U(F,C)= 0.20F 2 C 2 s F, C With food on the horizontal axis and clothing on the vertical axis, identify on a graph the set of point s that give Abel the same level of utility as the bundle (10, 5). Do the same for Eden on a separate graph. B. C. On the same two graphs, identify the set of bundles that give Abel and Eden the same level of utility as the bundle (15, 8). Do you think Abel and E den have the same preferences or different preferences? Explain.....can u show me how to do such kind of questions??
Great
thanks!!
wish my mathematics fundamentals were this solid
Could you please show on the graph, where is the middle point?
Hello. I've been using your 'Microeconomics and Macroeconomics' playlist and found this video missing from it, after watching the Budget Line video. Would you add it to the playlist, please?
what is the link to the budget line video ?
the slope of the tangent line at a point on the indifference curve = marginal rate of substitution
great explanation!
Thank you!
You really helped me!!
Why sal hasn't won an nobel yet
so Ted Mosby's really teaching Econ huh
Excuse me, you're in the wrong class!
Are you taking into account the non-satiable assumption? because it seems like you arent, because if u would, I think that the two points on your indifference curve can't coexist on the same curve. thx for anybodies reply
Sal is top 5 human being on earth and it's not even a discussion
Logic within economics, we're is my tylenol?
is the slope in other words is marginal rate of substitution the same thing as opportuniy cost?
Is it possible to make a long story short. It is madness.
What is the difference between Marginal Rate of substitution and Marginal opportunity cost?
Anyone explain me how does the TU is equal . I don't understand. Help me if you know
How are comments from 3/5 years ago but video was uploaded 6 months ago how did u do that
Time travel
He's a founding member of Illuminati!!! 🤫🤫
(*dont tell anyone*)
He edited the video which makes it more recent as at then.
So whenever you edit any already existing video the date will change to the new one
👍
But the marginal rate of substitution is that times -1
Hello r u God
I have a question why curve is of convex shape?
Because the MRS diminishes due to the law of DMU
Can you pls explain, Why should I consider the Indifference as a curve? Why cant i consider that as a straight line? Since the whole concept is assumed, why did not the maker of the curve, consider a straight line? What has made him to consider a curve?
Because we are relying on the concept of strict convexity, which is a more accurate representation of real-life when compared to the liner line
@@boonsuen1997 Thanks for your reply. So, do you mean that, all real life representations are curved? To be simple, why some graphs are curved and why some are lines in economics? What makes the difference between any curve and any line?
@@Masteridea101, For the most part, yes. It's a curve because your opportunity cost for one good to another will differ at different quantity, etc...
@@boonsuen1997 thanks a lot. Still I'm not clear. But anyway thanks a lot for your efforts to make me understand.
let me try to make this a little simpler
so marginal rate of substitution (MRS) basically means how much of B you're willing to sacrifice for gaining one more unit of A. say presently you're purchasing 1 unit of A and 10 units of B, since you're consuming very less of A as compared to B, you'd want more of A and you'd be willing to sacrifice a lot of B to gain 1 more unit of A
so let's say you sacrifice 5 units of B for 1 unit of A so your MRS will be 5/1=5
now you have 2 units of A and 5 of B
when you compare the two now you're consuming comparable amounts of both
if you could gain one more unit of A now you wouldn't be as willing to sacrifice a lot of B for that since the amount of B you have now is lesser than what you had before (ie 10) so you could say B becomes 'dearer' to you now that you have less of it.
so now to gain one more unit of A say you're willing to sacrifice only 2 units of B. now your MRS will be 2/1=2
so you see to consume more and more of A you'd be willing to sacrifice less and less of B and your MRS would keep on decreasing
since MRS represents the slope of your indifference curve you can say that the slope of the curve keeps on decreasing and that's why your plot cannot be a straight line it has to be a curve and since MRS ie the slope is constantly decreasing, it's a convex curve
I really hope I was able to explain this to you i tried to make this as easy as I could
bye:)
Why is this unlisted -_-
Daniel Mehta
thanks for the contents, it would be nicer if you could stop repeating yourself
so how exactly do I draw the Indiffrence curve?
@hanswurstfriz
Take the two goods whose preference you want to analyze on a co-ordinate plane. Then select any arbitrary point (x1,y1) on the plane. Now move some distance x' in any direction and question if you are better off or worse off at the point (x1+x', y1) as compared to (x1,y1). If the answer is yes then think how should I move(y') in y direction so that I am neither better off nor worse of than (x1,y1). You will now arrive at point (x1+x',y1+y'). At this point you are just indifferent in your preference as compared to (x1,y1). Join these two points and you have a section of your indifference curve. Now repeat this gazillion times 😋
So say you have a bunch of combinations of two goods right, and you have an arbitrary measurement of utility. Now what would happen if no two combinations produced the same utility? Would there be no indifference curve?
Indifference curves are assumed to be true. Doesn't matter if they're actually true or not. Microeconomics is very abstract.
I need to know how to find how many of both I can get with a budget and make a budget line. This video is all concept and no execution. 🤦🏽♀️
Didn't get it
Why didn’t my lecturer just say dat 🤦🏾♀️
Iron man: im indifferent
The ending confused me
No offense. But I would strongly suggest you illustrated these videos with animations / pictures, rather than hand writing. It gets quite tedious after a while. Other than that, keep up the good job!
ok phil
chill philip
Lol
take a chill pill Phil
ı love you/ ı hate my teacher
No man. This is terrible. Why is it useful? Why do we need it? Where are the examples? Where was it famously used? Sorry. All the comments are "this is awesome" I suggest groupthink. 😊
NO I DONT WANT TO EXPLORE BC
Thank you
