Quizplus · Accepted Answer

A change in demand refers to a shift of the demand curve, which occurs when there is a change in one or more of the determinants of demand, such as consumer preferences, income, prices of related goods, or population. A movement along a demand curve occurs when there is a change in the price of the good itself, which causes a change in quantity demanded, but not a change in demand. Similarly, the terms "demand curve" and "demand function" are often used interchangeably, but a function is a mathematical equation that relates demand to its determinants, while a curve is a graphical representation of that equation. Therefore, a shift of the demand function is not a meaningful concept in economics.
