2.3 Demand Shifters Lecture

What are normal goods in relation to income changes?

Normal goods are those for which demand increases as income rises.

How does a rise in income affect the demand curve for inferior goods?

A rise in income causes the demand curve for inferior goods to shift leftward as consumers opt for higher-quality substitutes.

What happens to the demand for normal goods when income falls?

When income falls, the willingness to pay for normal goods decreases, shifting the demand curve left.

What is the impact of consumer preferences on demand shifts?

Shifts in consumer preferences can drastically affect demand, moving the demand curve either right or left depending on whether preferences increase or decrease for a good.

How does an increase in the price of substitute goods affect demand?

When the price of substitute goods increases, the demand for the original good increases, shifting the demand curve to the right.

What occurs when the price of complementary goods rises?

A rise in the price of complementary goods will decrease demand for the paired good, shifting the demand curve to the left.

How does population growth influence market demand?

An increase in market size, such as population growth, will shift the demand curve to the right, increasing demand for products.

What effect do expected future price changes have on current demand?

If consumers expect lower future prices, current demand may decrease, shifting the demand curve left; if higher future prices are expected, current demand may increase, shifting the curve right.

Give an example of how an aging population may affect demand for certain products.

An aging population may reduce demand for products like pizza, resulting in a leftward shift of the demand curve.

What role do external factors play in influencing market demand?

Changes in consumer behavior, preferences, and external factors like prices of related goods can significantly influence market demand.
