#1
Which of the following is a characteristic of a perfectly competitive market?
Few sellers in the market
Homogeneous products
High barriers to entry
Price setting power of individual firms
#2
What does the law of diminishing marginal returns state?
As more units of a variable input are added, total output increases at a decreasing rate.
As more units of a variable input are added, total output increases at an increasing rate.
Total output remains constant regardless of the quantity of variable input.
Total output decreases as more units of a variable input are added.
#3
What is the main objective of a firm in a profit-maximizing model?
Maximizing revenue
Minimizing costs
Maximizing profit
Achieving market share dominance
#4
Which of the following is a characteristic of a monopolistic competition market structure?
Many sellers with differentiated products
One seller with a unique product
Few sellers with homogeneous products
Barriers to entry prevent new firms from entering the market
#5
What is the formula to calculate total variable cost (TVC)?
TVC = Total Cost - Fixed Cost
TVC = Average Variable Cost * Quantity
TVC = Marginal Cost / Quantity
TVC = Total Cost - Average Fixed Cost
#6
Which cost is not considered when calculating total cost?
Fixed cost
Variable cost
Sunk cost
Marginal cost
#7
In the long run, a firm operating in a perfectly competitive market will earn ________ profit.
Negative
Positive
Zero economic
Monopoly
#8
What is the formula to calculate marginal cost (MC)?
MC = (Change in Total Cost) / (Change in Quantity)
MC = (Change in Quantity) / (Change in Total Cost)
MC = (Total Cost) / (Quantity)
MC = (Quantity) / (Total Cost)
#9
What is the relationship between marginal revenue (MR) and price in a perfectly competitive market?
MR > Price
MR = Price
MR < Price
MR is undefined in perfectly competitive markets
#10
What does the production function represent?
The relationship between inputs and outputs
The relationship between fixed and variable costs
The relationship between revenue and profit
The relationship between price and quantity demanded
#11
What is the relationship between marginal cost (MC) and average total cost (ATC) at the point where ATC is at its minimum?
MC > ATC
MC = ATC
MC < ATC
MC is undefined at this point
#12
In the long run, a firm in a perfectly competitive market will produce at the level where ________ equals ________.
Marginal cost, average revenue
Marginal cost, marginal revenue
Average total cost, marginal cost
Average total cost, price
#13
In the long run, a firm in a monopolistically competitive market will produce at the level where ________ equals ________.
Marginal cost, average revenue
Marginal cost, marginal revenue
Average total cost, marginal cost
Average total cost, price
#14
What does the term 'economies of scale' refer to?
Increasing marginal cost as production increases
Decreasing average total cost as production increases
Increasing average variable cost as production increases
Decreasing marginal cost as production increases
#15
What is the formula to calculate marginal revenue (MR) in a perfectly competitive market?
MR = Price
MR = Total Revenue / Quantity
MR = Total Revenue - Total Cost
MR = Total Revenue * Quantity
