Question

Quizplus · Accepted Answer

A movement along a demand curve is a change in the quantity demanded and is caused by a change in the price of the good. This is because as the price of a good decreases, consumers are willing and able to purchase more quantity of the good, and vice versa. It is not a change in demand, which refers to a shift in the entire demand curve and is caused by factors such as changes in consumers' income, tastes and preferences, availability of substitute goods, and population size.
