Thank God for Khan Academy. my uni econs teacher is absolutely of no use

[likakramarchuk]

I spent so many days trying to understand my professor`s presentations... This video is amazing!

[lolislayer]

I felt so dumb when I couldn't explain perfect complements but now I still feel dumb but a lot more clear in the head thank you

[amaniabulaban]

my uni econ prof. spent half an hour trying to explain these while you only needed in five mins cool

[noueruz-zaman]

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

[rashikaushal]

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 thanks once again 🙏

[emilyheegaard]

SO MUCH BETTER THAN MY PROFESSOR AND TA COMBINED

For perfect substitutes, is the marginal rate of substitution (IC) constant or -1?

@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.

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

[mytinywrld]

Can you explain indifference curve for two goods that provide utility only upto a certain level beyonf that level they provide no utility???

[MikesLaffy]

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

[Geraxia]

"quantity of Raichu's" hahahaha @4:22

[scp]

greate explonation thank you your my hero

[Alejandra-jqxf]

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?

[ahmadsadiqallemyar]

Khan academy has made life easy. Thank you

[BurkeyAcademy]

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".

[molokoronaldraphadu]

Sounds like the person who makes tutorials on VB...well done, thanks teacher.

[Simas]

Seriously you're putting it now when my econ exam is tomorrow? Dam... :)

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.
