Bertrand Competition: Differentiated Products and Constant Marginal Costs

[@AkilBoii]

why did you use a different method in this video to your previous video on bertrand? and the profit function, are you not able to just do TR-TC? or just do the normal way of solving for MR=MC?

[@catherineannvergel-delacue1461]

This video is very helpful. Thank you

[@sihirliparmaklar6786]

Thank you sir you have saved my life !

[@Skey1337]

Why cant you set MR = MC for both firms?

[@jusufusillah8064]

Thank you so much

[@jiayichen9785]

Thank you it's quite helpful. Can I ask are the calculated prices the Nash equilibrium?

[@EconomicsinManyLessons]

Yes, the calculated prices give us a Nash eq.. Neither firm would want to change its price given the price being charged by the other firm.

@@EconomicsinManyLessons Thank you.

[@vinitkumarkshatri6676]

why is the method different in this than the other video? could you plz explain. I am confused.

[@nikhilagrawal2064]

great video

[@Dada-jx7gr]

how did you get the 0.953 😢

[@berenger9077]

thank you Sir

[@nketiajoseph880]

Please can you explain this to me Why did you ignore 4p2 when taking the partial derivative of firm 1.

[@EconomicsinManyLessons]

When we take a partial derivative with respect to one variable, we treat the other variable as a constant--and the derivative of a constant is just zero. In this case, we treat 4P^2 as a constant when taking the partial derivative of the function with respect to P1. This video might be helpful: kzbin.info/www/bejne/gJ3clY2ppLB9lbM

@@EconomicsinManyLessons why did you keep the other p2 then

[@matthewjhall3027]

would this be the working out for when they collude and act as a monopoly or when they don't collude and act separately?

[@EconomicsinManyLessons]

There is no collusion or acting like a monopoly in Bertrand competition.
