Proof: Cobb-Douglass is Special Case of CES 

"For my next trick, I'll take the same CES function and turn it into a Leontief utility function."

This really helped me a lot. I couldn't find any good answer online until I came upon your video. Very well explained - thank you! :)

very helpful! couldn't find another explanation this clear anywhere else, and instructors tend to hand-wave this.

Excellent Explanation. Please make a video on the Leontief Production Function as well. Thank you.

Presented with great clarity, I was looking for this. Thank you!

Thank you so much for this detailed video! The most useful explanation that I found.

Great video! Helped A LOT!!! Thanks!

That video helps me a lot. Thank you.

show that the leontief production function is a special case of the CES production function thank you

Thank you!

Very helpful 👍🏻

Wonderful

Your explanation is wonderful. Can you please be a professor?

why we needs to add natural logs before we check ?

How can we derive elasticity of substitution in case of fixed coefficient type production function?

Awesome!

Wouldn't an easier way to do this would be to show that the MRS of both CES and CD functions coincide when p=0? 🤔

Well, you are definitely not talking down to your audience. Is constant elasticity the same as perfect elasticity?

Could you do it for the Cobb-Douglas Utility Function when ρ -> 0 please? Initial utility function is: U = [ ∫ from 0 to n of q(ω)^ρ dω ] ^(1/ρ)
