How does Khan know every subject?? lol

[@myeongcho485]

Yes, he is the master sage :) ask him anything and he'll give the correct answer

[@DS-ff6ze]

He teaches most subjects at introductory level, so he's a jack of all trades.

[@riqui5406]

he probably learns them watching Khan academy

[@senthilvikramvodapalli1586]

But not better than my Google assistant. She even knows personal information of yours :)

[@樂樂樂-l5m]

@@senthilvikramvodapalli1586 you are just a scammer.

"Quantity... quantity... QUANTITY..." "nice tree... nice tree... NICE TREE..."

[@DisasterBanana]

i never should have taken an AP economics course...

[@omadityakarn4874]

hmmmmmmmmmmm

[@MrOllyMC]

Is this the same as the MPB/MSB/MSC that the UK Specification teaches?

[@fentondavies4308]

pretty much I think. I do as-level so might be slightly different at a-level

[@denizyuksel8936]

apparently you khan learn anything

[@beomkomap]

Despite some of the negative comments, Im understanding this video fully and found it super helpful. Hopefully can meet you in person one day sir!

[@pravs91]

Thank you so much. I think I can pass the exam tmoro :D

[@LucciOW]

so did you end up passing

[@92msgir]

god bless you.

[@ThePeterDislikeShow]

Wearing a mask in 2020 is almost entirely externality. Do these principles still work in the same way?

[@gabelincoln3608]

Yup

[@StephandaSilva]

Instead of adding the $10/tree to the demand curve, could you also deduct it from the marginal cost curve?

[@樂樂樂-l5m]

8 years, no reply for you. Khan = Khant.

[@caden7683]

yea

[@rizalATmarcos]

I gave up watching stupid videos on utube coz I've enrolled at KHAN ACADEMY! my substitute to 'music to my ears'

[@jawneejawstar909]

nice tree

[@paul1964uk]

But is it worth it, just by looking at the positions of the curves? @5:03 you could have an extra 1million trees/pa planted, but you have to give (2.7+1.0)million tax credits - and the 'deadweight' loss only looks like (1.0 million * $10)/2. That looks like $37m forgone for an imputed added benefit (from higher consumption) of $5million.

[@user-ik8ph1jz7n]

shut

[@Chiwun992]

life saver

[@gozdavid9671]

when you are writing, you are repeating words. you should keep talking.

[@louiswilliams8534]

why is math always so macro?! i need something else, like words or story or something

[@louiswilliams8534]

like, it goes nowhere - mathing

[@Yassine__2.0]

Hey,
I want to ask you how did you knew that it was 3,7 milion.
What did you do to become to that answer?

[@cfjrb]

The benefit is not all conferred on the consumer side. The new higher demand curve after the subsidy will result in a higher price along with the higher quantity so some of the benefit will go to the suppliers.

[@mike68536]

so what was the optimal level of production?

[@picklerick3136]

Cristal clear!!!!

[@Poppop-xl1jl]

There's a typo in the closed captioning at 3:10. It says "we're not talking about positive externalities," but what sal actually says is "we're now talking about positive externalities." you should change that so people don't get confused

[@derekeano]

Why do trees get more expensive to plant with a higher quality of trees to plant? Why does the cost per tree increase?

[@nicolastorres147]

The demand curve shifts up, making the price that producers receive increase. But with the tax credit, you get the price that consumers pay by going down to the demand curve, which is lower than 20 dollars.
Price received by producers = About $25 > $20
Price paid by consumers = Producer price - tax credit = $25 - $10 = $15 < $20
So both parties are better off.

[@jameslewis5534]

You sound like Eli the Computer Guy! Are you?

[@rajdeepsinhjadeja218]

Is their welfare loss in positive externality ?

[@salis5941]

this is so confusing

extremely confusing mate

[@charleslombe8501]

thanks a lot

[@mai2xs]

Accidentes chistoso

[@glenndwyer3071]

Wouldn’t such “external” benefits increase the consumers willingness to pay so be factored in, in the original demand curve? (Given that the demand curve depicts the price a consumer wants to pay, the reasons a consumer wants to pay a certain price are in fact determined by pest control, air quality and niceness)

[@fatmaalsharif3448]

thank you

[@thelord9999]

khan you make everything more worse off, sorry.

[@praneelmadhuvanesh3770]
