Final answer:
A change in a non-price determinant of demand results in a shift of the entire demand curve to the right or left, affecting the equilibrium price and quantity but not directly altering the supply curve.
Step-by-step explanation:
When a non-price determinant of demand changes, it leads to a change in demand, which results in the entire demand curve shifting to the right or left. This shift can be due to factors such as changes in consumer preferences, income levels, the prices of related goods like complements or substitutes, and expectations about future prices.
For instance, if a new technologically advanced video game is released, its demand might increase, causing a rightward shift of the demand curve. On the other hand, if a gaming console becomes obsolete due to a newer model with superior functionality, the demand for games compatible only with the old console may decrease, leading to a leftward shift of the demand curve.
These shifts affect the equilibrium price and quantity without directly affecting the supply curve. Instead, as demand increases or decreases, the quantity supplied will change accordingly, reflected by movement along the supply curve to reach a new equilibrium.
