Should the pink/purple demand curve be called the benefit curve instead? That's what it was in the negatve externalities video

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

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

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.

@glenndwyer3071 6 жыл бұрын

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)

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.

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

@nicolastorres147 Жыл бұрын

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.
