Suppose the demand for crossing the Golden Gate Bridge is given by Q = 10,000 − 1,000P. (LO6)
a. If the toll (P) is $3, how much revenue is collected?
b. What is the price elasticity of demand at this point?
c. Could the bridge authorities increase their revenues
by changing their price?
d. In 2019, the San Francisco Bay area Water Emer-
gency Transportation Authority (WETA) announced it was considering the implementation of hovercraft service as a supplement to existing ferries. Suppose that a fast hovercraft alternative to the Golden Gate Bridge is implemented between Marin County and San Francisco. How would the new service affect the elasticity of demand for trips across the Golden Gate Bridge?
For the first time in two years, Big G (the cereal division of General Mills) raisedcereal prices by 4 percent. If, as a result of this price increase, the volume of all cerealsold by Big G dropped by 5 percent, what can you infer about the own price elasticityof demand for Big G cereal? Can you predict whether revenues on sales of its LuckyCharms brand increased or decreased? Explain. (LO1, LO3)
Suppose that both wheat and corn have an income elasticity of 0.1 a. If the average income in the economy increases by 2 percent each year, by what percentage does the quantity demanded of wheat increase each year, holding all other factors constant? Holding all other factors constant, if 10 billion bushels are demanded this year, by how many bushels will the quantity demanded increase next year if incomes rise by 2 percent? b. Given that average personal income doubles in the United States about every 30 years, by about what percentage does the quantity demanded of corn increase every 30 years, holding all other factors constant?
