A gallon of gasoline emits about 19lbs of CO2 when burned. A $40/ton tax on CO2 emissions would add about $0.38 to the price of a gallon of gasoline, about a 15% increase in current gasoline prices. In the near term, what would be the percent decrease in quantity demanded for gasoline given the short run elasticity of demand for gasoline is -0.33.
-3.3%
-5%
-15%
-45%
No change in the quantity of gasoline demanded. Gasoline is a perfectly inelastic good.
Elasticity = percentage change in demand/percentage change in price
percentage change in price = 15%
Elasticity = -0.33
so, -0.33 = Percentage change in demand/15
Percentage change in demand = 15*-0.33 = -4.95 or -5%
so, the percentage decrease in quantity = 5%
option(B)

Question 5 Which of the following statements about the price elasticity of demand is correct? The absolute value of the elasticity of demand ranges from zero to one. The elasticity of demand for a good in general is equal to the elasticity of demand for a specific brand of the good. Demand is more elastic the smaller the percentage of the consumer's budget the item takes up. Demand is more elastic in the long run than it is in the short run. Question 6 The cross-price elasticity...

12. Study Questions #12 12. Study Questions #12 Opponents of increasing the tax on gasoline argue that the big oil companies just pass the tax along to the consumers. Do you agree or disagree? a. Agree because the demand for gasoline is less elastic than the supply, thus sellers can just pass the tax along to the consumers. b. Disagree because the demand for gasoline slopes downward and the supply curve slopes upward, thus sellers cannot raise the price by...
A good is considered normal when its income elasticity of demand is ___ and inferior when the its income elasticity of demand is ___. Greater than zero, less than zero. Less than zero, greater than zero. Greater than one, less than one. Less than one, greater than one. If an increase in prices decreases total revenue in the short run, what will it do to total revenue in the long run? It will decrease total revenue in the long run. It...

1)Consider two developments in the market for coal. The development of new mining technology is reducing costs. At the same time, electric utilities, a major buyer of coal, are switching natural gas due to the falling prices of natural gas. What is the consequence in the market given these 2 simultaneous changes? (note: since these 2 changes are occurring simultaneously, both the supply and demand curves could be changing) Coal prices will definitely fall Coal price will definitely increase Coal...
Describe in detail how your own actions reflect the ideas shared in the discussion, and relate that to the concept of elasticity. How responsive do you think consumers will be to the price change when these fluctuations occur due to changes in supply? Why? Use the various determinants of elasticity to explain your answer.
