@sveinntryggva You are correct if you are thinking that the value of y $10 bills is equal to trice as many $5 bills-- but that is not what we are talking about here. Sal has it right for describing points we are indifferent between: the line he drew was y=10-2x. At x=0,y=10 you have $50, and you also have $50 at (2,9), (4,8), etc. with a slope of -2, willing to trade 2 x for 1 y.
Thank u sir...u really explained the perfect substitutes case very well..I always wondered why in every book and website they always give the example .. of 1:1 ratio..whereas it can be any fixed ratio....... thanks once again 🙏
hello khan academy I have some questions about micro economic I like the teaching method of you can u tell me is there any difference b/w kinds of indifference curve and properities of indifference curve , and consumer equilibrium of equi marginal utility and equi marginal utility
Saying that these are "Normal Goods" in the first graph is incorrect. One of them might be an inferior good, especially with the way you drew them- higher budget, lower x. Inferior. You mean "the common case", but not "Normal Goods".
Under perfect compliments, why wouldn't the indifference curve have a slope of 1? That way the x and y would always be equal. With the right angle indifference curve, it looks like it could be 1 right shoe and 2 or 3 and so on left shoes.
Why are indifference curves important? Their objective is to show that goods trade according to rules or patterns. Why does that matter? Econ theory proposes a kind of trade pattern, the resolves to a math equilibrium. Purely deductive. But caution: deduction is axiom based. What are the axioms here? If you have a lot of one "normal" good, and a little of another, you give a lot up to get a little. Now think: food, clothes, transport, etc. You have many shifts, one pair of pants.
I'm afraid graph no2 is incorrect. Y=10$bills; x=5$ bills = y=2x would be the right function, but your plot suggests that 0 units of 10$ bills equals 2 units of 5$ bills. That would be a poor tradeoff :)
According to this hypothesis, if you have many shirts and few pants, you'll trade a lot of shirts for one more pair of pants. Would the person you trade with ask for more shirts, when you show up at a market? Without special knowledge, they can't tell if you have 1 shirt or 50. Further, if normal goods are common, you'd need to be a mental wizard to figure your point on all those simultaneous curves. If my one pair or pants is torn, II need to buy another pants, and be willing to pay more.
Maybe a bit late, but then the marginal rate of substitution would just be higher. (You would need 5 more of the less superior good to trade of one of the superior one)
But this is not "marginal", rather it's at the extreme. Once I've got pants on, I'll use my regular consumer skills to purchase more, whether #3 or #6. Once over-supplied with pants, then my attitude changes,. and I only buy great deals, perhaps. But this is again at the extreme, not at the margin. This isn't a curve; it's a step function. Sensible, probably easier to test. But it doesn't have a single equilibrium. Guess what - that's why it's a curve.
Thank God for Khan Academy. my uni econs teacher is absolutely of no use
A channel that deserves to be hit by throwing awards at it.
I spent so many days trying to understand my professor`s presentations... This video is amazing!
"quantity of Raichu's" hahahaha @4:22
my uni econ prof. spent half an hour trying to explain these while you only needed in five mins cool
i so so jealous of this guy's voice...
when i try to sound like morgan freeman i end up sounding like megan fox ..wtf
SO MUCH BETTER THAN MY PROFESSOR AND TA COMBINED

I thought he said "the quantity of Raichu's" and got rather excited to see where he was going with that xD
calm down goof
Absolutely helpful

I LOVE KHAN ACADEMY!
Seriously you're putting it now when my econ exam is tomorrow? Dam... :)
Great video!!!!
Thanks so much! Your vids really help me understand my homework! =)
Khan academy has made life easy. Thank you
Sounds like the person who makes tutorials on VB...well done, thanks teacher.
" I should have dine red M&Ms from red" how thoughtful :D
greate explonation thank you your my hero
Thanks bro
Very useful
Thank you 😊

i love this contain ❤❤❤❤❤❤❤❤❤❤
thanks for the vid ! it really helped me
and this is the quantity of squirtles :D
Khan, do a video on SOPA!

Editor Edited It 1.5 right shoes for 1.5 left shoes? Haan????
Thank you, loved the m&m example haha
Not to hate on my economics teacher, but I've always understood everything better from you than from her.

How does the MRS change as we move to higher utilities in the normal good case? Are in general the curves associated to higher utility flatter?
would a close substitute curve for 2 goods be the same as the curve for normal goods?
What is the elasticity of perfectly subtitutes indifference curve ?
I'm afraid graph no2 is incorrect. Y=10$bills; x=5$ bills
= y=2x would be the right function, but your plot suggests that 0 units of 10$ bills equals 2 units of 5$ bills. That would be a poor tradeoff :)
For perfect substitutes, is the marginal rate of substitution (IC) constant or -1?
According to this hypothesis, if you have many shirts and few pants, you'll trade a lot of shirts for one more pair of pants. Would the person you trade with ask for more shirts, when you show up at a market? Without special knowledge, they can't tell if you have 1 shirt or 50.

tq
pokemon go - RAICHU !!!
Can you explain indifference curve for two goods that provide utility only upto a certain level beyonf that level they provide no utility???
How do you make an indifference curve for a product that has 4 parameters to it?
What about when one good is a superior version of another?
Maybe a bit late, but then the marginal rate of substitution would just be higher. (You would need 5 more of the less superior good to trade of one of the superior one)
nice work professor!
left shoes and right shoes classic example just like my professor, that has a lot of assumptions like you have two legs. hahaha
In 4:22 I thought he said "Raichu's" when he said "Right Shoes",
lol.
Havent heard someone say m&ms so much
i saw this in class
@hedonism13 He did
