The estimated market demand function
for electric vehicles (E) is
Q = 182 - 6PE +
3PG + 5Y,
and the supply function is
Q = 122.+
4PE
- Solve for equilibrium price and quantity in the market for
electric vehicles. The price of electric vehicles is
PE, the price of gasoline-powered cars
is PG, and household income is
Y.
Currently the price
of gasoline-powered cars, PG, is 40
(thousand dollars) and household income, Y, is 48
(thousand dollars).
- At the market equilibrium, what is consumer surplus?
- Suppose that the price of gasoline-powered cars increases from
40 to 46 (thousand dollars). What is consumer surplus in the market
for electric vehicles at the new equilibrium?
- In a diagram, please draw the original (inverse) demand
function and the supply function. Note the original equilibrium.
Then draw the new (inverse) demand function after the increase in
the price of gasoline-powered cars. Note the new equilibrium. Shade
in the consumer surplus for both.
