42. Cournot versus Bertrand Basics

[@ssilverism]

The fact that is so lucid and clear and helpful makes me irritated with my professors...

[@BaggaFlexx]

same sentiments..

bit of a jump at 5:32 to obtaining marginal revenue by taking intercept and twice of slope. If anyone else is confused by this the reason is that when you multiply price by quantity(q1) you get total revenue = 30q1 - q1q2 -q1^2. Differentiating this expression with respect to q1 gives marginal revenue = 30-q2-2q1.

[@samya6081]

Could you explain how q1=10 please?

[@HeavenQuab]

@@samya6081 For anyone still confused, at 7:32 , he assumes symmetric cost functions, further reinforced at 8:00 ; this means q1 = q2. So by changing q2 to q1 in the equation, we arrive at < q1 = 15 - (1/2)q1 >, therefore < (3/2)q1 = 15 >, making < 3q1 = 30 >, and finally, < q1 = 10 >.

I am a Economics student from Bath Uni in the UK. Thank you so much for your help along the years. You have a really clear mind :) I really enjoy your explanations. Please keep up the nice work. Love for the UK :)

[@intromediateecon]

I'm close. I'm a PhD Candidate at UChicago (done with classes, far on research). Hopefully, I'll have a PhD before long. Thanks for the comment.

[@yanma7766]

how did it go? curious to know! thank you for the video, helped a lot for the revision of my industrial economics exam!

[@HeavyBlues101]

Dude this is the greatest thing ever. You should add a donation link. Seriously.

[@yourdeadmother]

hey bro. i just want to say youre actually really good at teaching this shit and clearly it can only mean youre really smart and you know what is going on.

[@jenniferelisa]

You just saved my life. Thank you so much!

[@PreciousTusingwire]

Thank you so much for this excellent Explanation. you just taught me how to defend this topic. thank you so so much

[@mixedbloood]

I´m on the run but i really want to give you some props for your vids on oligopolies! i am rather spoiled concerning tutorial vids since i m a huge fan of Salman Khan, but yours´ are very well done as well! one can feel that you love economics and you make it easier for us to start to love it! ;)

[@AruSharma04]

That was quite quick, to clarify between 3 models. Thanks a lot man.

[@Eco1Nomics]

Thanks a bunch I am studying for qualifiers and I have been struggling to really relate the three... Cournot, Stackelberg and Bertrand. Thank you.

[@alfonsorodriguez1763]

I agree with Sam Silver below - you explained this exceptionally well - thank you!

[@shefalipradhan5516]

Great videos. Much help provided. But the videos are low on sound, kindly increase it in the upcoming videos. Thanks.

[@theviolator23]

@wetterbabe Solve the equation for you wrote down for q1 and you get ten. To check the answer substitute 10 into both q1's and see if the sides are equal. 10=15-.5*10 10=15-5 10=10 The solution is therefore valid, and because no variable is raised to any power outside of 1 there is only one solution.

[@Senvirr]

I sincerely thank you sir,good explanation,nice comparison,really you are my idol now

[@dalilhaitionboy]

Very helpful!!! you got my thumbs up and subscription but future reference "Get out the way!" I can't see the other side of the board im writing notes here

[@Simran-xn7ec]

I can't believe this is so simple! My book really sucks

[@DesktopOrganizers]

Could you do a video covering the Hotelling Model? Please and thank you!

[@wetterbabe]

great video... but still not sure how q1 equals 10 at the end... how do we go from: q1=15-1/2q1 to q1=10 after we have said that q1=q2...

[@rusty5809]

Still very helpful in 2024. Special thanks from The Netherlands!

[@90ben09]

Can I ask a question, you say around 5:20 that, in order to get your expression for marginal revenue, you take the same intercept with half the slope. I can see what this looks like and how to use it but why is the marginal revenue curve equal to this?

[@alekxu]

Wow you are a really good teacher. Thank you sir.

[@Hpstr115]

Very helpful man thanks.Has anyone ever told you that you sound exactly like Seth Rogan?

[@econbusiness7334]

very smart to write on the board and stand in front it all the time

[@ariannacardenas1428]

the industry of soft drinks, focusing on coke and pepsi because they are the major player would you consider that to be a cournot competition or a bertrand competition ? i am very confused

[@Swarleynator]

would you mind doing a video about the calculus of Bertrand Model in duopol with differentiated products? that whole beta and gamma stuff if you know what I mean!? :) Would be awesome, thanks ! :)

[@winnie_small_busniess_corner]

You just saved me from failing my industrial economics class!!!

[@FrederikLambert]

how did you get the adidas sponsorship?

[@oh.smetanka]

Superb video!

[@divyyy4358]

Excellent explaination!

[@skeeman42018]

Do you have a PhD? You are sharp sir! I wish all my professors were as concise and knowledgeable as you. Great Job!

[@lobsterbanker]

Better than my UCSD professor!

[@onecanina]

Really good video!!

[@cpanone]

Very helpful and clear. Thank you

[@Huilenexotic]

Life saving, hope to do decently in my midterm XD

[@j127123]

Nice clip! However, the sound is very soft.

[@varunjashnani3120]

Thank you, amazing explaining

[@cshin2717]

Thanks alot! Awesome lecture

[@UHLMANDL]

Your mannerisms remind me of Jason Segal (which is awesome)

[@amyvong1210]

You're standing in the way of your own notes, but otherwise this was very easy to understand, and good teaching!

[@Chriscx]

so pause the video when he steps out of the way

[@emiistudy6678]

@NeverFear AThing absolutely

[@GBDazzler]

Sorry this may sound stupid but, where did the "30" in the equation come from?

[@LungteNangram]

That's a constant. It represents all the other effects to the demand other than price. It came from the formula.

[@GDInspirations]

30-q is just an example ! You can write 100-q and p=mc would be 0 in bertrand's case.

[@suyog85]

great video. thanks!

[@thenarfer]

Great stuff!

[@MrMPAROUARE]

Sir, How is life? Are you done with the PhD?

This is wonderful. Why can't class be taught like this always? I gotta say though, the sound quality is terrible.
