Question

Which of the following will cause a movement along the demand curve instead of a shift of the demand? curve?

A.

Income

B.

Expectations of the future price of a good

C.

Tastes and preferences

D.

none of the above

Answer 1

Movement along the demand curve happens when there is change in quantity demanded.

Change in quantity demanded happens when there is change in price.

Change in income, change in expectations with respect to the future price of a good, and change in tastes and preferences brings change in demand and not the change in quantity demanded.

So, these factors leads to shift in demand curve and not the movement along the demand curve.

Hence, the correct answer is the option (D).
