Cournot 

I learned more in this 14:08 minute video than the 40 minutes I tried to learn about Cournot from my book. Thank you!

This was great :) Could you please make videos on Bertrand and Stackelberg too?

this is the best economics channel . period.

Finally I understood the topic! Many thanks!!!!!!:)

I still do not understand why the marginal cost is fixed instead of upward sloping.
