Income Effect(16)
What is the income effect?
The income effect describes how a change in a consumer's income influences their purchasing decisions for goods and services.
True or False: The income effect only applies to luxury goods.
False. The income effect applies to all goods, affecting demand as income changes.
How does an increase in income affect demand?
An increase in income generally leads to an increase in demand for normal goods.
What is a normal good?

Fill in the blank: An increase in income decreases demand for ______ goods.
inferior
Give an example of the income effect.
If a consumer’s income rises from 60,000, they may buy more organic food.
What happens to demand for inferior goods when income rises?
Demand for inferior goods, like instant noodles, typically decreases as consumers opt for higher quality alternatives.
How does the income effect differ from substitution effect?
The income effect relates to changes in purchasing due to income changes, while substitution effect focuses on changes due to price changes.
What is the effect of a price decrease on demand for normal goods?
The income effect from the price decrease can make consumers feel richer, increasing demand for normal goods.
True or False: The income effect can be negative.
True. If a good is inferior, increased income can lead to decreased demand.
Explain how the income effect relates to consumer surplus.
As income increases and demand rises, consumer surplus may also increase, implying greater satisfaction.
What is an example of a Giffen good?
A Giffen good, like bread during a famine, may see increased demand despite a price rise due to the income effect.
What happens to demand for luxury goods when income increases?
Demand for luxury goods typically increases significantly as consumers feel more financially secure.
Define inferior goods.
Inferior goods are products whose demand decreases as consumer income rises.
How does the income effect influence consumer choices?
Changes in income shift the consumer's budget constraint, affecting their choice of goods.
Illustrate the income effect with a graph.
A graphical representation shows the budget line shifting outward as income increases, leading to higher consumption of goods.
Substitution Effect(16)
What is the substitution effect?
The substitution effect refers to the change in quantity demanded of a good when its price changes, leading consumers to substitute it with a cheaper alternative.
True or False: The substitution effect only applies to luxury goods.
False. The substitution effect applies to all goods, regardless of their classification.
Give an example of the substitution effect.
If the price of coffee rises to 3.
How does the substitution effect influence consumer choices?
Consumers tend to buy less of a good that has become more expensive and more of a substitute that is now relatively cheaper.
Fill in the blank: The substitution effect helps explain changes in _______.
demand due to price changes.
Comparing two goods: When the price of good A rises, what happens to good B?
Good B, if a substitute, typically sees an increase in demand.
What happens to the quantity demanded of a good when its price falls?
The quantity demanded increases, and substitutes become less attractive.
True or False: The substitution effect can lead to a decrease in overall market demand.
False. The substitution effect generally reallocates demand rather than decreases total market demand.
Explain the income effect's relation to the substitution effect.
While the substitution effect focuses on price changes, the income effect considers how changes in purchasing power influence overall consumption.
What does a consumer do when a substitute becomes relatively cheaper?
They are likely to purchase more of the cheaper substitute.
Give a real-world example of substitution effect.
If movie ticket prices rise, people may choose to stay home and watch a streaming service instead.
How does the substitution effect impact budget constraints?
As prices change, consumers adjust their consumption choices within their budget constraints to maximize utility.
What is the effect of a price decrease for a good?
It can lead to an increase in quantity demanded of that good and a decrease in demand for its substitutes.
Define relative price in the context of substitution effect.
Relative price is the price of one good compared to another, influencing consumer choice between substitutes.
True or False: The substitution effect can lead to a decrease in consumer surplus.
False. The substitution effect generally increases consumer surplus as consumers find cheaper alternatives.
How does advertising influence the substitution effect?
Effective advertising can increase the appeal of substitutes, leading consumers to switch based on perceived value.
