Third bottle 3
Fourth bottle 2
Fifth bottle 1
Further bottles 0
The cost of producing a bottle of Zlurp is $1.50, and the competitive suppliers sell it at this price. (The supply curve is horizontal.)
Each Whovillian will consume ___ bottles and receive a consumer surplus of $_.
Producing Zlurp creates pollution. Each bottle has an external cost of $1.
Taking this additional cost into account, total surplus per person in the allocation you previously determined decreases to $_.
Cindy Lou Who, one of the residents of Whoville, decides on her own to reduce her consumption of Zlurp by 1 bottle.
Cindy's consumer surplus (ignoring the cost of pollution she experiences) is now $_. Her decision _ (Increases or Decreases) total surplus in Whoville by $_.
Mayor Grinch imposes a $1 tax on each bottle of Zlurp.
Consumption per person is now_bottles. This yields a per-person consumer surplus of $_not including the cost of pollution, a per-person external cost of $_, and government revenue of $_ per person. Total surplus per person is now $_as a result of this policy. (Hint: Total surplus is equal to consumer surplus minus the external cost of pollution plus government revenue.)
Based on your calculations, you _ (Would or Would not) support the mayor's policy because it ___ (Increases or Decreases) welfare compared to before the tax.

1) This 4 is chosen because the marginal benefit will be less than the marginal cost and if it wants to go above that, the price of the drink is greater than the willingness to pay

2) The consumer surplus is

= (5 - 1.5) + (4 - 1.5) + (3 - 1.5) + (2 - 1.5)

= 8

3) Total surplus decreases to

As we know that

= Consumer surplus - external cost

= 8 - 4

= 4

4) Now Cindy's Consumer surplus is

= (5 - 1.5) + (4 - 1.5) + (3 - 1.5)

= 7.5

5) Increases

6) 8 - 7.5 = 0.5

7) Consumption = 3 bottles

8) Consumer surplus is

= (5 - 2.5) + (4 - 2.5) + (3 - 2.5)

= 4.5

9) External cost = 3 × 1 = 3 bottle

10) Government revenue = 3 × 1 = 3 bottle

11) Total surplus is

As we know that

= Consumer surplus - external cost of pollution + government revenue

= 4.5 - 3 + 3

= 4.5

12) would

13) increases
