The way you sigh before you continue the problem is a mood, even if you're just out of breath or tired.

lol u are so unenthusiastic I love it

I love you. Never forget that. You can pin this so if you're ever feeling sad, you can come back to this video to remind you that you've saved lives.

this made so much more sense to me than my professor or any other youtube video ive watched on the subject. thank you so much!

This is my review for my 300 level econ course. A huge thank you for making this straight forward.

Thank you so much, you have no idea how much of a lifesaver you are smh. My midterm is tomorrow (half my grade!!) and I wasn't getting this until I saw your video. I just finished 2 problems w/ your help. God bless you sir.

This video is a life saver. I was struggling so bad at this but you explained it so well. Thank you so much

I love you 😭😭😭, I have a test today! Now I understand this so well

Great job man! this really helped. At the end to find Y, you can also plug in x=10 into your original Y= 8/5x :)

KZread carries students understanding of stuff. Thank you sir

you saved my semester, I owe you my degree

Great video, this made the concept of utility maximization much easier to understand!

I am watching this video before my end exam . It was more helpful to my paper . The way you teaches better than our professor. Thank you so much.❤️

Very useful video! Really liked the way you showed how to solve it rather than skipping steps like other tutorials. Only issue was I had to speed it up 1.5x because voice over was really slow haha

Thanks so much for this lesson. I now understand equilibrium.

I love you💟💟 I've been looking for this for some time now

Please make more of such videos. Well explained 👏🏾👏🏾

GR8 VID, saved me in my econ hw, thanks!

Lovelyyyyyyyy!! I finally understood how to solve this problem!! Thank you so so much!

duuuude you rock! Also the sighs killed me lol

thanks man, that video was extremely helpful:)

THANK YOU SO MUCH, YOU SAVED ME!

It's really clear to me.Thank you very much❤️

This video saved my bacon. Massive thanks!

OMG thank you so much for this video!

well-done now I got an insight to solve similar problem

Dude, you may have jut saved my life. I would love to sign a lifelong binding contract that entitles you to 50% of my futere earnings in the economic sphere.

thanks so much, you saved me with this micro

man you are killing it !!!!!!!

thank you so much, this really helped

I love it❤,,,i never understood my lec on that concept,,, Thanks 🙏

Great job!

Great tutor..Thanks

thank you very much for the video. i have been struggling with a similar problem where U=(x+14)(y-2) px=4 and the combination of goods was 86x and 52y . I was asked to calculate the income. I didnt have a clue to solve untill i did a derivation of the function and so on...thank you! now I can move on!

How did u solve the differentiation of the utility

Considero está bien explicado! I hope more see 🇪🇨

Thank you!

Thank you!!!

merci pour cette video utility function: ça marche aussi pour 3 variables ( private goods, leisure, public goods); merci à youtube!

Wonderful lecture

Superb sir

omg thank you so much!!!!!!!!!!!!!!!!!!!!!!!

just saved my life

does it works for every utility funciton ? cobb-douglas, quasi linear ecc.?

if you use the Lagrange method do you have to plug the number you divided by back into the constraint and solve

thankyou so much

Nice video.. why no more videos on this channel?

You have no idea the extend at which you have saved my school semester.

help!!, what if i dont know MRS (3xy^2) and just have the solutuion MRS=1/2 … 1/2=4/5? makes no sence

how did you get U(x,y)=3xy^2? or is that just how the equation is always because i thought U=xy?

@thecinimod

U(x,y) = 3xy^2 is the utility function. In textbook or exam problems this is almost always just given. It can take many different forms, so sometimes it might be = xy, sometimes it might be = 3xy^2, sometimes it might be = 2x + y^0.5 or even something else. Each different way we can model the utility function gives slightly different properties and preferences for the consumer, and determines which bundles the consumer would like more than which other bundles. So ultimately how the utility function looks will depend on what real types of preferences we are trying to represent with this mathematical model.

Mu utility was 76800 & yours was 7680 please explain order of operations for calculating 3xy^2 did you only square the 16 instead of the result of the 16 and 10?

mans a W ngl

Where did you get the 6xy?

what if the slope of the utility isn't equal to the budget line, like the result of the derivative of the utility equals 1/2 but the X=1 y=3, so the slope of the budget line equals to 1/3? How can I find the bundle point?

Life Savior 💪💪

LIFE SAVER THANK YOU

what if i just get a scalar instead of y = (some)x, i get y = 8

I have a question. my question reads supposed you have 5 fish and 5 coconuts to get an extra unit of fish you have to give up 2 coconut. draw a budget line

Neat

Hey, i found my teacher a little bit tricky, where x is py is 4. And y is px is 2. How i supposed to do? Px/Py = MUx/MUy; or Py/Px = MUx/MUy? And i did the second. Am i wrong?

Uh bra, uh are genius

i love u bby

Woww at least my heart is at rest

Please I’m lost on how you get the 3xy square and the 6xy , all that I saw is that you started writing that without any explanation and I’m now taking Econ’s at university so please help me out

pleaseeee do more videos

what if the utility function is first order

Is this interior solution?

how does MUy become 6xy How can the square disappear and the 3 become a 6. Great video though helpful process to follow

@Toobadsososad

It's the partial derivative of the function with respect to y. The derivative of (y^2) is 2y, multiply that with (3x) which does not change since it is considered a constant when computing the partial derivative. The result is (3x)*(2y) = 6xy. :)

Hey how can i go ahead to work on roy’s identity from that step you got (7680) . Thansk

Is the utility function U(X,Y)= 3XY^2 given in the question??

You have mentioned u(x,y) = 3xy^2 ....Is that supposed to be an assumption

sorry how did you get U(x,y)=3xy^2 ?

@FagnerDeschain

7 жыл бұрын

it is given, it could be any function

PX/PY should not be - PX/PY, due to the fact that it is a decreasing slope?

@Meatcrob1

7 жыл бұрын

yes that is true, but the MRS is always (-1) the slope of the indifference curve. Since the IC is always negative for normal goods, it's implied that the MRS will be positive. He didn't explicitly show it, cause it's assumed.

shouldn't it be -Mux/MUy? so -y/2x or am I missing something?

How did you calculate marginal utility of y=6xy?

@glorig4152

7 жыл бұрын

you just take the derivative of U(x,y)=3xy^2 with respect to y so you bring down the 2 and you have 2 * 3xy^(2-1)= 6xy

Sigh~~~lol, but really thank you so much!

please stop sighing . good video tho

🎉U=x the power of 0.5 times y the power of 0.5
