Third-Degree Price Discrimination: How to Solve

This video provides a detailed example on how a firm practices third-degree price discrimination.
Typo: in domestic market TR = 110Q - Q^2, the MR is correct and everything else.
In foreign market TR = 30Q - Q^2, the MR is correct and everything else.
Best,

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!

[@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 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.

[@Skey1337]

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?

extremely well explained

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

Thank you 💕

thank you

[@yusrasajjad4705]

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

You are an absolute lifesaver. Any Patreon links where one can contribute?

[@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.
