#1
Which of the following is a characteristic of a perfectly competitive market?
Many buyers and many sellers
ExplanationPerfectly competitive markets have a large number of buyers and sellers, leading to price-taking behavior.
#2
Which of the following is NOT a determinant of demand?
Technology
ExplanationTechnology is a factor affecting supply, not demand, in microeconomics.
#3
What is the concept of 'opportunity cost'?
The cost of an item in terms of the next best alternative foregone
ExplanationOpportunity cost represents the value of the best alternative forgone when a decision is made.
#4
Which market structure is characterized by a single seller with significant control over price?
Monopoly
ExplanationIn a monopoly, there's a single seller dominating the market, allowing significant control over prices.
#5
Which of the following is a characteristic of a monopoly market?
One seller and many buyers
ExplanationMonopoly markets feature a single seller with many buyers, leading to high barriers to entry.
#6
Which of the following is a characteristic of monopolistic competition?
Many sellers and differentiated products
ExplanationMonopolistic competition involves many firms selling differentiated products in a market with low entry barriers.
#7
In microeconomics, what does 'elasticity' measure?
The responsiveness of quantity demanded to a change in price
ExplanationElasticity measures how much quantity demanded changes in response to a change in price.
#8
What is the primary objective of a monopolistically competitive firm?
Maximize profits
ExplanationMonopolistically competitive firms aim to maximize profits by differentiating their products.
#9
What is the formula for calculating price elasticity of demand?
Percentage change in quantity demanded divided by percentage change in price
ExplanationPrice elasticity of demand is calculated by comparing the percentage changes in quantity demanded and price.
#10
What happens to consumer surplus when price decreases in a market?
Consumer surplus increases
ExplanationAs price decreases, consumer surplus increases due to increased consumer welfare.
#11
What does the production possibility frontier (PPF) illustrate?
The trade-off between production of two goods given limited resources
ExplanationPPF shows the maximum combinations of two goods that can be produced given resource constraints.
#12
What does the law of diminishing marginal utility state?
As consumption of a good increases, marginal utility decreases
ExplanationThe law states that as consumption of a good increases, the additional satisfaction derived from each additional unit decreases.
#13
What is the relationship between marginal cost and marginal revenue in perfect competition when a firm is maximizing profit?
Marginal cost equals marginal revenue
ExplanationIn perfect competition, profit maximization occurs when marginal cost equals marginal revenue.
#14
What is the relationship between marginal revenue and price elasticity of demand for a monopolist?
Marginal revenue is less than price elasticity of demand
ExplanationIn monopoly, marginal revenue is less than price elasticity of demand, influencing pricing decisions.
#15
Which of the following is a characteristic of a perfectly elastic demand curve?
It is vertical
ExplanationPerfectly elastic demand indicates that quantity demanded changes infinitely with any change in price.
