#1
Which of the following is a characteristic of perfect competition?
A large number of buyers and sellers
ExplanationPerfect competition is characterized by a large number of buyers and sellers, leading to market equilibrium.
#2
In which market structure does a firm have the least control over the price of its product?
Perfect competition
ExplanationFirms in perfect competition have the least control over the price of their products, as prices are determined by market forces.
#3
What happens to a perfectly competitive firm's marginal revenue when it increases its output?
It stays constant
ExplanationIn perfect competition, marginal revenue remains constant as output increases, as each unit is sold at the same price.
#4
What is the relationship between price and marginal revenue for a monopolist?
Price is greater than marginal revenue
ExplanationIn monopoly, price is greater than marginal revenue, resulting in a downward-sloping demand curve.
#5
What is the relationship between marginal revenue and average revenue for a perfectly competitive firm?
They are equal
ExplanationIn perfect competition, marginal revenue and average revenue are equal, as each unit is sold at the same price.
#6
What is the relationship between total revenue and price in a perfectly competitive market?
They are directly proportional
ExplanationIn perfect competition, total revenue and price exhibit a direct proportional relationship due to constant market prices.
#7
In a monopoly, what is the shape of the marginal revenue curve?
Downward sloping
ExplanationThe marginal revenue curve for a monopoly is downward sloping, reflecting the reduction in revenue associated with producing additional units.
#8
What is the relationship between price elasticity of demand and total revenue?
They have an inverse relationship
ExplanationTotal revenue and price elasticity of demand share an inverse relationship; as price elasticity increases, total revenue decreases.
#9
Which of the following is a characteristic of monopolistic competition?
A large number of firms
ExplanationMonopolistic competition is characterized by a large number of firms, each offering slightly differentiated products.
#10
What is the relationship between marginal revenue and total revenue for a perfectly competitive firm?
They are equal
ExplanationIn perfect competition, marginal revenue equals total revenue, as each additional unit is sold at the same price.
#11
If a firm's total revenue is increasing at a decreasing rate, what can be said about the price elasticity of demand?
Demand is elastic
ExplanationWhen total revenue increases at a decreasing rate, it indicates elastic demand, where a price increase results in a proportionally larger decrease in quantity demanded.
#12
What is the formula for calculating total revenue?
TR = P × Q
ExplanationTotal Revenue (TR) is calculated by multiplying price (P) and quantity (Q), represented by the formula TR = P × Q.
#13
What is the formula for calculating average revenue?
AR = TR / Q
ExplanationAverage Revenue (AR) is calculated by dividing Total Revenue (TR) by Quantity (Q), represented by the formula AR = TR / Q.
#14
Which of the following is true about the relationship between marginal revenue and total revenue for a monopolist?
Marginal revenue is zero when total revenue is maximized
ExplanationTotal revenue is maximized for a monopolist when marginal revenue becomes zero.
#15
Which of the following is true about a monopolist's demand curve?
It is downward sloping
ExplanationA monopolist's demand curve is downward sloping, reflecting the negative relationship between price and quantity demanded.
#16
In a perfectly competitive market, what is the profit-maximizing output level for a firm?
Where marginal revenue equals marginal cost
ExplanationThe profit-maximizing output level for a firm in perfect competition is where marginal revenue equals marginal cost.
