#1
In long-run cost analysis, what does the long run refer to?
A period of time in which all factors of production are variable.
ExplanationLong run refers to a period where all production factors can be adjusted.
#2
Which of the following is a characteristic of economies of scale?
As production increases, average total cost decreases.
ExplanationEconomies of scale involve decreasing average total cost with increased production.
#3
What is meant by the term 'diseconomies of scale'?
When the cost per unit increases as the scale of production increases.
ExplanationDiseconomies of scale: Increasing cost per unit with production scale.
#4
Which of the following cost curves represents the relationship between the quantity of output produced and the total cost incurred?
Total cost curve
ExplanationTotal cost curve depicts the relationship between output quantity and total cost.
#5
What is the difference between economies of scale and diseconomies of scale?
Economies of scale occur when average total cost decreases with increased production, while diseconomies of scale occur when average total cost increases with increased production.
ExplanationEconomies of scale vs. Diseconomies of scale: Cost trends with production.
#6
Which cost concept is represented by the change in total cost resulting from producing one additional unit of output?
Marginal cost
ExplanationMarginal cost represents the change in total cost for one additional unit of output.
#7
Which of the following statements about economies of scope is true?
Economies of scope refer to the ability of a firm to produce multiple products at a lower cost per unit than producing each product separately.
ExplanationEconomies of scope: Lower cost per unit for multiple products.
#8
What does the LRAC curve depict in the long-run cost analysis?
The relationship between average total cost and the quantity of output produced when all inputs are variable.
ExplanationLRAC curve shows the relationship between average total cost and output quantity with variable inputs.
#9
What is the shape of the long-run average cost curve when experiencing constant returns to scale?
Horizontal
ExplanationConstant returns to scale result in a horizontal long-run average cost curve.
#10
What is the primary reason for the existence of economies of scale?
Technological advancements
ExplanationEconomies of scale are primarily driven by technological progress.
#11
Which of the following is NOT a potential source of diseconomies of scale?
Technological progress
ExplanationDiseconomies of scale do not stem from technological progress.
#12
What does the LRMC curve represent in the context of long-run cost analysis?
The relationship between marginal cost and the quantity of output produced when all inputs are variable.
ExplanationLRMC curve: Relationship between marginal cost and output quantity with variable inputs.
