Principles of Consumer Behavior and Utility Maximization Quiz

#1

Which of the following is a basic assumption of consumer behavior according to utility theory?

Consumers always make rational decisions.
Explanation

Utility theory assumes consumers consistently make rational choices.

#2

What is the law of diminishing marginal utility?

As consumption of a good increases, its total utility decreases.
Explanation

The law states that each additional unit of a good provides less satisfaction.

#3

What is the difference between total utility and marginal utility?

Total utility measures total satisfaction while marginal utility measures additional satisfaction.
Explanation

Total utility is the overall satisfaction, while marginal utility is the satisfaction gained from consuming one more unit.

#4

What is the concept of 'consumer surplus'?

The difference between the maximum price a consumer is willing to pay and the market price.
Explanation

It represents the additional value consumers receive when paying less than their maximum willingness to pay.

#5

What is the concept of 'marginal rate of substitution' (MRS) in consumer theory?

The rate at which the consumer is willing to trade one good for another while maintaining the same level of utility.
Explanation

It represents the willingness to exchange goods on an indifference curve.

#6

Which of the following best describes the 'law of demand'?

As prices fall, demand rises.
Explanation

It states that there is an inverse relationship between the price of a good and the quantity demanded.

#7

Which of the following represents the budget constraint equation?

Px + Py = M
Explanation

This equation shows the trade-off between the prices of two goods and the consumer's income.

#8

What does the slope of an indifference curve represent?

The marginal rate of substitution (MRS) between two goods.
Explanation

It indicates the rate at which a consumer is willing to exchange one good for another while maintaining the same level of satisfaction.

#9

What is the Hicksian demand function derived from?

Substitution and income effects
Explanation

It is based on the impact of changes in prices (substitution effect) and changes in real income (income effect).

#10

What is the difference between ordinal and cardinal utility?

Ordinal utility considers preferences without measuring intensity, while cardinal utility measures intensity of preferences.
Explanation

Ordinal utility ranks preferences, while cardinal utility assigns numerical values to intensity.

#11

Which concept describes the tendency of individuals to imitate the consumption choices of others?

Veblen effect
Explanation

It is the phenomenon where the demand for a good increases as its price rises, signaling status or exclusivity.

#12

What is the Engel curve used to illustrate?

Income-consumption relationship
Explanation

It shows the relationship between the quantity of a good consumed and consumer income.

#13

What is the main assumption behind the consumer equilibrium in microeconomics?

The consumer is perfectly rational and has complete information.
Explanation

The assumption is that consumers make decisions based on rationality and complete information.

#14

Which utility function exhibits constant elasticity of substitution?

Perfect substitutes utility function
Explanation

This utility function assumes a constant rate at which one good can be substituted for another.
