#1
Which of the following is a fundamental assumption of consumer choice theory?
Consumers always make rational decisions.
ExplanationAssumes consumers consistently make optimal choices.
#2
According to the theory of consumer choice, what is the rational consumer expected to do?
Maximize total utility subject to the budget constraint.
ExplanationAim for highest satisfaction within budget limits.
#3
What is the concept of 'revealed preference' in consumer theory?
It is the idea that preferences can be inferred from observed consumer choices.
ExplanationDeriving preferences from actual choices.
#4
What is the concept of 'marginal utility' in consumer choice theory?
It is the total satisfaction derived from consuming one additional unit of a good.
ExplanationSatisfaction gained from consuming an extra unit.
#5
What is the primary assumption behind the concept of 'rational behavior' in consumer choice theory?
Consumers always maximize their own satisfaction.
ExplanationAssumption of self-maximizing behavior.
#6
What does the law of diminishing marginal utility state?
The marginal utility decreases as consumption increases.
ExplanationDeclining additional satisfaction with increased consumption.
#7
What is the budget constraint in consumer choice theory?
The consumer's income and the prices of goods and services.
ExplanationLimits spending based on income and prices.
#8
What role does the concept of 'opportunity cost' play in consumer decision-making?
It is the value of the best alternative forgone in making a choice.
ExplanationValue of foregone alternatives in decision-making.
#9
How does the Engel curve illustrate the relationship between income and demand for a normal good?
It demonstrates a direct relationship between income and demand.
ExplanationShows increased demand with rising income.
#10
According to consumer choice theory, what is the relationship between the price elasticity of demand and consumer responsiveness to price changes?
Higher price elasticity implies higher responsiveness to price changes.
ExplanationMore elastic demand reacts strongly to price changes.
#11
In consumer choice theory, what does the concept of 'ordinal utility' emphasize?
It emphasizes the ranking or ordering of preferences without measuring the magnitude of satisfaction.
ExplanationPrioritizing preference order over magnitude.
#12
In the context of consumer choice, what is the meaning of the term 'marginal rate of substitution'?
The rate at which the consumer can substitute one good for another while maintaining the same level of satisfaction.
ExplanationRate of exchange between goods with constant satisfaction.
#13
What is the significance of an indifference curve in consumer choice theory?
It depicts combinations of goods that provide the same level of satisfaction to the consumer.
ExplanationIllustrates equally preferred consumption bundles.
#14
What is the significance of the Gini coefficient in the context of consumer welfare?
It measures income inequality among consumers.
ExplanationQuantifies disparity in consumer incomes.
#15
How does the substitution effect differ from the income effect in response to a price change?
Substitution effect is the change in quantity demanded due to changes in prices, while the income effect is related to changes in income.
ExplanationChange in demand due to price vs. income changes.
#16
How does the introduction of a new technology affect consumer choices according to the theory of consumer behavior?
It expands the set of feasible consumption choices.
ExplanationIncreases available consumption options.
#17
What is the role of the Lagrangian multiplier in consumer optimization problems?
It helps incorporate constraints into the optimization process.
ExplanationFacilitates constraint integration in optimization.
