What is described as a change in quantity demanded due to a change in price?

The concept of a change in quantity demanded due to a change in price refers specifically to how consumers respond to different price levels while keeping other factors constant. This behavior is illustrated by movement along the demand curve.

When the price of a good decreases, consumers tend to buy more of that good, leading to an increase in quantity demanded. Conversely, an increase in price usually results in a decrease in quantity demanded. This relationship is captured by the law of demand, which determines how the curve shifts or how movements occur along it based on price changes.

Movement along the demand curve effectively shows the direct impact of price changes on the quantity of items that consumers are willing to purchase, highlighting the inverse relationship between price and quantity demanded. This principle is fundamental in understanding basic supply and demand dynamics in economics.
