Suppose that the price elasticity of demand for heating oil is 0.2. If the price of heating oil rises from $1.80 to $2.20 per gallon, what will happen to the quantity of heating oil demanded in the short-run?
Suppose the price elasticity of demand for heating oil is 0.2 in the short run and 0.7 in the long run. c. If the price of heating oil rises from $1.80 to $2.20 per gallon, what happens to the quantity of heating oil demanded in the short run? In the long run? (Use the midpoint methodin your calculations.)
3. Problems and Applications Q3 Suppose the price elasticity of demand for heating oil is 0.1 in the short run and 0.9 in the long run If the price of heating oil rises from $1.80 to $2.20 per gallon, the quantity of heating oil demanded will by % in the long run. The change is heating oil. by % in the short run and in the long run because people can respondeasily to the change in the price of Grade...
Suppose subway ridership in New York City declined by 10 percent after a fare increase of 25 cents to $2.75. Using the midpoint method, an estimate of the price elasticity of demand for subway rides is . True or False: According to your estimate, the Transit Authority's revenue rises when the fare increases. True False
The cab fare in Horseville is regulated. Recently, the government decided to raise it from $2.00 to $2.50 per ride. After this rise in fare, cab ridership decreased by 10 percent. a) What is the price elasticity of demand for cab rides in Horseville? Explain your answer (10 marks) b) According to your estimate, what happened to the cab drivers' revenue after the fare rose? Explain. (5 marks) c) Why...
2 One day you open the paper and read: "The number of subway rides in decrease by 8%, the first full month after the price token had risen by 50 cents to $1.50. a. Use these data to estimate the price elasticity of demand for subway rides in that period. b. According to your estimate, what happens to the Transit Authority's revenue when the fare rises? 3 Suppose firm F has the following marginal cost: MC = 2 + 6Q...
The price elasticity of demand for crude oil in the U.S. has been estimated to be -0.061 in the short run and -0.453 in the long run. Is demand for crude oil in the U.S. price elastic? Why would the demand for crude oil be more price elastic in the long run than in the short run?
4. (25 points) The following table provides data on price elasticities related to public transit. Suppose the current price of a ride on public transit is $1.00. Peak riders ride at rush hour, off-peak riders travel at other times. Elasticity El for Public Transit (Peak Riders) El for Public Transit (Off-Peak Riders) Cross-Price Elasticity of Demand for automobile trips with respect to public transit fare price Short Term 0.25 0.45 Long Term 0.50 0.90 0.25 0.07 a. Explain why the...
5. Determinants of the price elasticity of demand
Consider some determinants of the price elasticity of
demand:
• The availability of close substitutes
• Whether the good is a necessity or a luxury
• How broadly you define the market
• The time horizon being considered
A good with many close substitutes is likely to have relatively
__(Elastic, Inelastic)___ demand since consumers can easily choose
to purchase one of the close substitutes if the price of the good
rises.
A...
3. (Chap 3, 4.1) The short-run price elasticity of demand for oil is 0.3. If new discoveries of oil increase the quantity of oil by 6 percent, what will be the resulting change in the price of oil?
