Consumers are solely motivated by price changes.
Consumers have no preferences when making choices.
#3
11. According to the substitution effect, how does a decrease in the price of one good affect the consumption of another good?
It increases the consumption of the substitute good.
It decreases the consumption of the substitute good.
It has no effect on the consumption of any other goods.
It reduces the overall consumption of all goods.

It demonstrates the difference between total utility and marginal utility.
It questions the validity of the law of diminishing marginal utility.
It highlights the challenge of measuring utility in terms of diamonds and water.
#5
21. What is the 'Law of Demand' in consumer economics?
It states that the demand for a good increases as its price increases.
It asserts that the demand for a good decreases as its price increases.
It claims that the demand for a good is unaffected by changes in its price.
It suggests that the demand for a good is directly proportional to its price.
#6
2. What is the budget line in consumer choice theory?
A line representing the consumer's income
A line representing the prices of goods and services
A line representing the consumer's preferences
A line representing the quantity of goods and services consumed
#7
3. In utility theory, what does the term 'marginal utility' refer to?
The total satisfaction from consuming a good
The additional satisfaction from consuming one more unit of a good
The price of a good
The total amount of money spent on goods and services
#8
7. How does a normal good differ from an inferior good in consumer theory?
Normal goods have a positive income elasticity, while inferior goods have a negative income elasticity.
Normal goods are always more expensive than inferior goods.
Normal goods are necessities, while inferior goods are luxury items.
Normal goods are only purchased by wealthy consumers, while inferior goods are for lower-income individuals.
#9
8. In the context of utility theory, what does the term 'transitivity' mean?
Consistency in consumer preferences, implying that if A is preferred to B and B is preferred to C, then A must be preferred to C.
The constant change in consumer preferences over time.
The willingness of consumers to trade goods at any price.
The idea that consumer preferences are solely influenced by external factors.
#10
12. What is the difference between 'total utility' and 'marginal utility'?
Total utility is the additional satisfaction from consuming one more unit of a good, while marginal utility is the overall satisfaction.
Total utility is the satisfaction derived from consuming all units of a good, while marginal utility is the satisfaction from the last unit consumed.
Total utility represents the consumer's preferences, while marginal utility measures the quantity of goods consumed.
Total utility and marginal utility are interchangeable terms in consumer choice theory.
#11
13. In consumer theory, what is the 'law of equi-marginal utility'?
Consumers allocate their income equally among all goods and services.
Consumers maximize utility by equalizing the marginal utility per dollar spent across all goods.
Consumers always prefer more of a good to less.
Consumers only consider the total utility when making consumption choices.
#12
17. How does the concept of 'elasticity of substitution' relate to consumer preferences?
It measures the responsiveness of quantity demanded to changes in the price of a good.
It indicates how easily a consumer can substitute one good for another.
It explains the impact of changes in consumer income on the quantity demanded of a good.
It quantifies the change in consumer preferences over time.
#13
4. What is the difference between cardinal and ordinal utility?
Cardinal utility measures utility in numerical terms, while ordinal utility ranks preferences without assigning specific values.
Cardinal utility is only applicable to luxury goods, while ordinal utility is for essential items.
Cardinal utility is based on subjective preferences, while ordinal utility relies on objective measurements.
Cardinal utility focuses on the quantity of goods, while ordinal utility considers the quality of goods.
#14
5. What is the concept of 'indifference curve' in consumer choice theory?
A curve representing the consumer's changing preferences over time
A curve showing different combinations of goods that yield the same level of satisfaction to the consumer
A curve indicating the quantity of goods demanded at different price levels
A curve representing the consumer's diminishing marginal utility
#15
9. What is the significance of the Engel curve in consumer choice theory?
It shows the relationship between the quantity of a good consumed and its price.
It illustrates the effect of changes in consumer income on the quantity demanded of a good.
It represents the slope of the budget line in consumer choice.
It measures the elasticity of demand for a particular good.
#16
10. Explain the concept of 'revealed preference' in consumer theory.
It refers to the preferences consumers express when surveyed about their choices.
It is the idea that consumer preferences are only revealed through actual choices and behavior.
It represents the preferences consumers wish to reveal but are hesitant to express openly.
It is a hypothetical model that predicts consumer preferences without observing actual choices.
#17
14. How does the concept of 'time preference' relate to consumer choice theory?
It refers to the preference for goods that provide immediate satisfaction over those that provide satisfaction in the future.
It is the idea that consumer preferences are not influenced by the passage of time.
It indicates the preference for goods that take a longer time to produce.
It is the willingness of consumers to trade goods over time without considering their preferences.
#18
15. What role does the 'income effect' play in consumer choice theory?
It describes the impact of changes in the price of a good on the quantity demanded.
It explains how changes in consumer income affect the quantity demanded of a good.
It measures the responsiveness of quantity demanded to changes in consumer preferences.
It has no relevance in understanding consumer choices.
#19
19. How does the 'Hicksian demand curve' differ from the 'Marshallian demand curve'?
The Hicksian demand curve shows the relationship between quantity demanded and income, while the Marshallian demand curve represents the relationship with price.
The Hicksian demand curve is based on consumer preferences, while the Marshallian demand curve focuses on market demand.
The Hicksian demand curve considers the substitution effect, while the Marshallian demand curve does not.
The Hicksian demand curve is only applicable to inferior goods, while the Marshallian demand curve applies to normal goods.
