[martiong]

dude, you're good…!

Fantastic job explaining these concepts.

im doing hessians in my math econ class. what do hessians have to do with econ? im confused :(

[cbx3460]

very helpful. Thanks a lot. I understand that you wanna make your lectures less boring by editing the steps. If you have time, why don't you post two versions: both the entire lecture and the edited lecture. Smart ones follow the edited ones, slower ones like me follow the complete one.

@cbx3460 That's a good suggestion. Unfortunately, for the old videos, I don't have the full footage anymore (just the edited files). I'll keep this in mind for future videos in this format.

can you do an example with numbers please ?

[Oscargs7]

would it kill you to slow down!

[intromediateecon]

@Oscargs7 I agree. This video goes through the material quickly, but that's intentional. I do it to prevent boredom... watching someone write on the board is boring. It is the explanation that is interesting. If I go through something too quickly (i.e., jump frame to put some math on the board), you are welcome to pause the video to spend some time absorbing the math.

@intromediateecon

Thanks now i get it, there´s a good paper covering the basics behind the theorem from the U of Berkeley i strongly recommend it before watching the video... Tnx!

[intromediateecon]

@Oscargs7 Thanks for the reference. I found some helpful notes from a Berkeley teaching assistant on this topic, and I linked them in the description of the video.

For what it is worth, this is my most "technical" video on my channel. Most of my other ones rely much more on intuition than grinding through mathematical details. I also prefer my follow up video on applications of the envelope theorem to this one. It isn't really the proof that matters... it is the vast scope of applications.

@Oscargs7 is it the  emlab.berkeley thing that discusses consumer and envelope theorem?

[toulouselucas]

helpful!!!!!!!!!

[Prektesh1]

that was great. You are a great instructor

[DeusAmadeus1]

Thanks! :D

[Eliseme]

Thank you. You've made it a lot easier for me to understand.

[elenak643]

great lecture

[harkerhh]

Thanks for uploading. It´s hard to find this kind of study material in an understandable way.
