Demand for New Domestic Cars*
QNA=-500PNA + 250Px + 125M -100,000,000R+20,000 Pop + 600A
Where Q'NA is quantity demanded of new domestic cars, PNA is the average price of new
domestic cars, Px is the average price of new import luxury cars, M is average annual household
income, R is the average interest rate (in decimal format), Pop is the population (in millions),
and A is the annual dollars spent on advertising on new cars (in millions).

a. What is the demand curve for new domestic cars if Px = $60,000, M = $56,000, R = 8
percent = 0.08, Pop=300 million, and A = $5,000 million?
Draw the demand curve for new domestic cars.
b.
c. According to the equation above, are new domestic cars and new import luxury cars
substitutes or complements? Explain.
d. According to the equation above, are new domestic cars normal or inferior goods?
Explain.
e.
f.
Ceteris paribus, if the price of new import luxury cars increases to $62,000 what
happens to the demand curve for new domestic cars? Be as specific as possible.
Ceteris paribus, if Px = $60,000 but the average annual household income falls to
$50,000, what happens to the demand curve for new domestic cars? Be as specific as
possible.

g. Find the inverse demand curve for new domestic cars when Px = $60,000, M = $56,000,
R = 8 percent, Pop=300 million, and A = $5,000 million.
h. What happens to the demand curve for new domestic cars if the average price of new
domestic cars increases from $30,000 to $35,000?
i. Use the inverse demand curve to determine how much the price must change for
consumers to buy 1 million more domestic cars per year.
