Third-Degree Price Discrimination: How to Solve

[@bd145dc]

You are an absolute legend! As an econ student I wish I discovered you much much earlier. No useless talk, no unnecessarily long math stuff, just the stuff that is necessary. Legend that's what you are!

When you mukltiplay Q into the equation (110-Q) * Q - shouldnt you multiply Q into both Q and 110 resulting in Q = 110Q - Q^2??

[@EconomicsinManyLessons]

Thank for catching that.. Yes, you are right. The marginal equations are correct though.

[@davidgranell4941]

You saved my life. Great explanation!!! Very simple and on point.

[@harveymusonda3230]

Thank you so much... I almost gave up. You've simplified everything. Thank you

When you calculate potential "profit" for uniform pricing at 7:30 - why do you plug Q = 60 into the total cost function and not Q = 70 like in the expression for TR?

[@timothykagan2498]

extremely well explained

(110-Qd)Qd= 110Qd - Q^2 d but sit you solved this ie 110- Q^2d

How do we calculate producer surplus, consumer surplus and deadweight loss of this problem?

[@samer9530]

man what a goat, you're a G

[@yusrasajjad4705]

When u solve for both markets during multiplication why there is Not qd with 110?

[@fb4680]

Thank you 💕

[@simonmasunda4695]

how do you get 10 at 3:27?

[@EconomicsinManyLessons]

The 10 is the firm's marginal cost of production. In the beginning of the video, I give the firm's cost function and then take a derivative of it to get marginal cost of 10.
