#1
Which of the following best describes utility in economics?
The ability of a product to satisfy human wants
ExplanationUtility refers to the satisfaction or usefulness a consumer derives from consuming a good or service.
#2
Which of the following is NOT a characteristic of a perfectly competitive market?
Barriers to entry for new firms
ExplanationPerfectly competitive markets are characterized by easy entry and exit for firms, with no barriers preventing new firms from entering.
#3
What is the law of demand?
As the price of a good increases, the quantity demanded decreases
ExplanationThe law of demand states that there is an inverse relationship between the price of a good and the quantity demanded, assuming other factors remain constant.
#4
What is consumer surplus?
The difference between the highest price a consumer is willing to pay and the price they actually pay
ExplanationConsumer surplus represents the benefit consumers receive when they are able to purchase goods or services at a price lower than what they are willing to pay.
#5
What is the law of diminishing returns?
As more units of a variable input are added to a fixed input, the marginal product of the variable input eventually decreases
ExplanationThe law of diminishing returns explains that if one input is increased while all others are held constant, the marginal product of that input will eventually decrease.
#6
What does the law of diminishing marginal utility state?
The more of a product a consumer has, the less satisfaction they will derive from each additional unit
ExplanationThis law suggests that as a consumer consumes more of a product, the additional satisfaction gained from each additional unit decreases.
#7
Which of the following factors does NOT typically influence consumer preferences?
Geographical location
ExplanationConsumer preferences are usually influenced by factors such as price, quality, and personal tastes rather than geographical location.
#8
What is the formula for calculating total utility?
Total utility = Marginal utility * Quantity
ExplanationTotal utility is the sum of all marginal utilities, which is calculated by multiplying the marginal utility of each unit consumed by the quantity consumed.
#9
Which of the following is an example of a non-price determinant of demand?
Income of the consumer
ExplanationNon-price determinants of demand include factors such as consumer income, preferences, expectations, and the number of buyers in the market.
#10
Which of the following is NOT a type of market structure?
Competition
ExplanationCompetition is a generic term and not a specific market structure; examples of market structures include perfect competition, monopoly, oligopoly, and monopolistic competition.
#11
What is the difference between cardinal utility and ordinal utility?
Cardinal utility measures satisfaction in exact units, while ordinal utility ranks preferences without measuring satisfaction quantitatively
ExplanationCardinal utility assigns numerical values to utility, while ordinal utility simply ranks preferences without assigning specific values.
#12
In consumer theory, what does the term 'income effect' refer to?
The change in quantity demanded of a good due to a change in consumer income
ExplanationThe income effect explains how changes in consumer income impact the quantity demanded of goods and services.
#13
What is the main assumption of the indifference curve analysis?
Consumers always make rational decisions
ExplanationIndifference curve analysis assumes that consumers consistently make rational decisions to maximize their utility based on their preferences and budget constraints.
#14
In economics, what does the term 'elasticity' refer to?
The sensitivity of quantity demanded to a change in price
ExplanationElasticity measures the responsiveness of quantity demanded to changes in price, indicating how sensitive consumers are to price changes.
#15
Which of the following is NOT a determinant of supply?
Consumer preferences
ExplanationDeterminants of supply include factors such as input prices, technology, expectations, number of sellers, and government policies, but not consumer preferences.
