1). Suppose the demand for computers. For each of the following, state the effect on demand:
a.An increase in consumer incomes.
b.An increase in the price of computers.
c.A decrease in the price of internet service providers.
d.A decrease in the price of semiconductors.
e.It is October, and consumers expect that computers will go on sale just before Christmas.
2). The demand curve is given by
Qd = 500 - 5Px + 0-5 I + 10Py - 2Pz
Where
Qd = quantity demanded of good X
Px = price of good X
I = consumer income, in thousands
Py = price of good Y
Pz = price of good Z
a.Based on the demand curve above, is X a normal or an inferior good?
b.Based on the demand curve above, what is the relationship between good X and good Y?
c.Based on the demand curve above, what is the relationship between good X and good Z?
d.find the equation of the demand curve if consumer incomes are $30,000, the price of good Y is $10, and the price of good Z is $20?
e.Graph the demand curve that you found in (d), showing intercepts and slope.
f.If the price of good X is $15, what is the quantity demanded? Show this point on your demand curve.
g.Now suppose the price of good Y rises to $15. Graph the new demand curve.
