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?
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?
@@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?
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:)
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
@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?
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!
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. 😊

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?
These videos are much better than anything I have been taught at University.
Crystal clear. Thank you Sal. I do not know how much knowledge you have in your mind.

awesome crystal clear vid! thankss

YOU ARE A GIFT....!!!
the slope of the tangent line at a point on the indifference curve = marginal rate of substitution
Thank you khan academy you are the best
great and simple explanation! Thanks.

Fantastic explanation.
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:)

So whenever you edit any already existing video the date will change to the new one
Merci beaucop!
Thank you
Is it possible to make a long story short. It is madness.
How does it become negative 5?
I have a question why curve is of convex shape?
Because the MRS diminishes due to the law of DMU
I LUV U
But the marginal rate of substitution is that times -1
is the slope in other words is marginal rate of substitution the same thing as opportuniy cost?
great explanation!
Anyone explain me how does the TU is equal . I don't understand. Help me if you know
Why is this unlisted -_-

Hello r u God
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
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.
Why didn’t my lecturer just say dat 🤦🏾♀️

The ending confused me
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. 🤦🏽♀️
