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!

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

[TheQsanity]

How does Khan know every subject?? lol

[pravs]

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

[MrOllyMC]

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

[StephandaSilva]

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

[DisasterBanana]

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

[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.

[mike]

so what was the optimal level of production?

[pauluk]

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.

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

[ThePeterDislikeShow]

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

[rizalATmarcos]

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

[Yassine__.]

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?

[rajdeepsinhjadeja]

Is their welfare loss in positive externality ?

[glenndwyer]

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)

[derekeano]

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

[jameslewis]

You sound like Eli the Computer Guy! Are you?

[gozdavid]

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

[louiswilliams]

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