Chapter 10, Problem 6PA
The many identical residents of Whoville love drinking Zlurp. Each resident has the following willingness to pay for the tasty refreshment:
a. The cost of producing Zlurp is $150, and the competitive suppliers sell it at this price. (The supply curve is horizontal.) How many bottles will each Whovillian consume? What is each person’s
b. Producing Zlurp creates pollution. Each bottle has an external cost of $1. Taking this additional cost into account, what is total surplus per person in the allocation you described in part (a)?
c. Cindy Lou Who, one of the residents of Whoville, decides on her own to reduce her consumption of Zlurp by one bottle. What happens to Cindy’s welfare (her consumer surplus minus the cost of pollution she experiences)? How does Cindy’s decision affect total surplus in Whoville?
d. MayorCrinch imposes a $1 tax on Zlurp. What is consumption per person now? Calculate consumer surplus, the external cost, government revenue, and total surplus per person.
e. Based on your calculations, would you support the mayor’s policy? Why or why not?

Use the graph attached below as a starting point (either download it or print it out). Add curves, labels, etc. to this graph in order to show the following:
1. Show that this good has a $4/unit negative externality (external cost), such as pollution.
2. Shade the area that represents the Deadweight Loss (lost gains from trade) caused by the external cost.
3. Show a tax or subsidy wedge (whichever you think is appropriate) that will solve the problem of the external cost.
4. Show the socially optimal level of production that the Pigouvian tax or subsidy above will help the market to achieve.
You may use software or pencil and paper to complete this graph. Upload it here when you are done.
Identify at least one positive externality from running a donut shop. Identify at least one negative externality from running a donut shop. Explain how these positive and negative externalities could impact the donut shop’s profits. (Hint: think subsidy for positive externality and tax for negative externality.) Draw two graphs that show the price of donuts before and after the positive and negative externality impacted the price of your donuts.

- This summer, the temperature records on each other's feet seem to be beaten. In Sweden, the temperature has recently risen to 43 degrees and birds are falling from the sky over exhausted and dying. Carbon emissions are one of the main challenges facing mankind today. Explain the market failure caused by the emissions. Under competitive conditions, the government can use various control tools to establish efficient quantities, e.g. with a fee. Show the effect of such a solution on a diagram and explain in detail why an economical amount involves some pollution. In a monopoly situation, it is not as simple as establishing efficiency by charging emissions. Explain in words and pictures how the different interplay between the cost factors of a company and pollution costs can cause certain government tariffs on pollution to be cost-effective on the one hand and inefficient on the other.arrow_forwardLet the supply and demand for widgets be given by the following schedule.
