You have the ability to explain complex concepts in an intuitive way... Which makes you a better teacher than most and a lot better at explaining ideas than the vast majority of textbooks which have a ridiculously arcane and non-intuitive way of explaining things.
Bro, MRS = -delta Y/delta X. Don't forget the negative when writing your formula. Because one would wonder where the negative at the end goes. For instance the way you wrote it MRS from A to B should be -2 but you just dropped the negative without explanation and indicated that it is 2. It's positive because initially there was a negative sign in the formula which when multiplied with another negative it became positive. Otherwise, the explanation was clear and simple.
Just a little thing: At 5:20, you say y is 20-10 = -10. I think you meant 10-20, as you've got to calculate the NEW value take away the OLD value. :) Additionally, i think it was supposed to be (70-40), not (40-70)..
Thanks! That is what I like to hear. Make sure you like MyBookSucks on Facebook (see link in video description). This will help other students find the educational videos.
Thanks for the compliment. Often in economics the slope is ignored or dropped. I am working on some new videos on Consumer Theory where I discuss this explicitly. Great observation tho!
I can not thank you enough for this. But I face a problem I wish to go sequentially through all the videos. But can't figure out the sequence. For example I just listened to 'How to find our MRS using indiffrence curve' But which is the next video I should listen to? will you please guide? Thanks again
W's utility function is U (x; y) = xy. W consumes 5 units of x and 25 of y. a)W would be willing to make small exchanges of x for y in which he gives up 5 units of x for every unit of y he gets b) W would be willing to trade away all of his x for y so long he gets more than 5 units of y for every unit of x he gives up (continuing)
You are very welcome! Happy to hear the channel is helping you. I have channels on statistics, algebra and calculus too. You can see the links on MyBookSucks FB page. Make sure you like MyBookSucks on FaceBook(see linking video description). This will help others find the educational videos too.
.. c) W likes x and y equally well so he is always willing to exchange 1 unit of either good for more than one unit of the other d) W will always be willing to make trades at any price if he doesn't have equal amounts of the two goods e) None of the above why is e) the correct answer?
Hi! I've noticed a massive mistake in your video that confused me. You're explaining the mean rate of substitution-the marginal rate of substitution is only calculated with one point using a tangent. I failed a multiple-choice question because of that :)
Nadia, yes I do have some videos on how to calculate the derivative. If you go to my channel economicsfun, you can search on the word calculus and you will see several videos and one of the is on MRS. If you need more help it is probably easiest to send me a message on the MyBookSucks FaceBook Page.
Yes many economics books suck, for sure. I thought for a very long time that economics lends itself to animation -- instead of trying to figure out graphs in a book.
Hi was just wondering how we would calculate an indifference curves with diminishing rates of substitution that meet at some initial allocation? thank you
It does not make much of a significant difference though, as we are looking at the absolute value for our conclusion. Thanks for raising the point though.

You just saved me so much time. thank you
Really I watched many videos but don’t understand, only from you I get it mmmmmmmuuuchh thanks

Thanks for this. Pearson's textbook and online course over-complicates formulas making it appear to much more complicated than it is.
Wow, why couldn't you be my professor. You've essentially made a day lesson short and sweet.
appreciate the kind words. I keep trying to get the word out, so make sure you tell your suffering fellow students.

Right, often in economics we drop the sign because it is implied. I should have mentioned that explicity.
I don't have Facebook, but I will definitely spread the word around class
Right, this is a bad habit I have of ignoring signs. I will fix this video in a revised version. Thanks for good observaton.
this is amazing. Thank you!!!!
yooooooooo what a gem that i found this
Wow, this video aided the famous Johnny Harris in acquiring his economics degree!
What the hell? I never thought I would see you in a youtube comment section about Marginal Rate of Substitution LOL.
I can not thank you enough for this. But I face a problem I wish to go sequentially through all the videos. But can't figure out the sequence. For example I just listened to 'How to find our MRS using indiffrence curve' But which is the next video I should listen to? will you please guide? Thanks again
Try referring to the index of a microeconomics text book. That would help you in arranging.
Thank you for such an articulate and positive comment. I really appreciate it.
Just wondering, at 3:15 you did -20/10=2 shouldn't it be equal to -2 instead?
He forgot a negative sign in the formula at the beginning.
W's utility function is U (x; y) = xy. W consumes 5 units of x and 25 of y.
a)W would be willing to make small exchanges of x for y in which he gives up 5 units of x for every unit of y he gets
b) W would be willing to trade away all of his x for y so long he gets more than 5 units of y for every unit of x he gives up
(continuing)
hloo
in which standard are you bro

you're a great teacher man!!!!! you make this shit seem like 1+1, keep it up
..
c) W likes x and y equally well so he is always willing to exchange 1 unit of either good for more than one unit of the other
d) W will always be willing to make trades at any price if he doesn't have equal amounts of the two goods
e) None of the above
why is e) the correct answer?
My book does suck haha thank you for the great instruction it relieved so much frustration
It has made life easier
Love this video!
Where are the other thousand like buttons? Like + Subscribed
holy crap thank you for this channel
if it is none of the above what is the correct answer?
thanks!!
very very useflu video...helped me with my dumb aplia homework haha Thanks!

I tried reading my book but it just couldn't understand it. Thank you so much!!! really helpful
Point C to D is INCORRECT!!!!!! It is not consistent with the first two points.
Yes many economics books suck, for sure. I thought for a very long time that economics lends itself to animation -- instead of trying to figure out graphs in a book.
Great video, thanks a lot :D

Understood

i hate economics so much
i still hate economics
I don't have a FaceBook :)
thanks so much!
