#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, promoting competition.
#2
In economics, what does the term 'marginal cost' refer to?
The cost of producing one additional unit of a good or service
ExplanationMarginal cost represents the additional cost incurred to produce one more unit of a good or service.
#3
Which of the following is a characteristic of a monopoly market?
Barriers to entry
ExplanationMonopoly markets are characterized by barriers to entry, restricting new competitors from entering the market.
#4
Which of the following is not a factor affecting production costs?
Market demand
ExplanationMarket demand is not a factor directly affecting production costs, which are influenced by input costs and production processes.
#5
What is an example of a variable cost for a software development company?
Cost of software licenses
ExplanationThe cost of software licenses is a variable cost for a software development company, as it varies with the quantity of software produced.
#6
In the short run, which cost remains fixed?
Fixed cost
ExplanationIn the short run, fixed costs remain constant regardless of changes in production levels.
#7
What does the short-run average variable cost curve typically look like?
U-shaped
ExplanationThe short-run average variable cost curve is U-shaped, indicating the relationship between average variable cost and output.
#8
What is the formula for calculating total cost?
Total cost = Fixed cost + Variable cost
ExplanationTotal cost is the sum of fixed and variable costs, expressed by the formula Total cost = Fixed cost + Variable cost.
#9
What does the law of diminishing returns state?
As more units of a variable input are added to fixed inputs, the marginal product of the variable input decreases
ExplanationThe law of diminishing returns asserts that adding more of a variable input to fixed inputs will eventually result in diminishing marginal returns.
#10
What is the relationship between marginal cost and average variable cost?
Marginal cost intersects average variable cost at its minimum point
ExplanationThe intersection of marginal cost and average variable cost occurs at the minimum point of the average variable cost curve.
#11
What does economies of scale refer to?
The range of output over which long-run average total cost decreases as output increases
ExplanationEconomies of scale describe the output range where long-run average total cost decreases as production levels increase.
#12
What is the formula for calculating average fixed cost?
Average fixed cost = Total fixed cost / Quantity of output
ExplanationAverage fixed cost is computed by dividing total fixed cost by the quantity of output.
#13
What does the long-run average total cost curve typically look like in the case of economies of scale?
Downward sloping
ExplanationIn economies of scale, the long-run average total cost curve slopes downward as production increases.
#14
What is an example of a fixed cost for a manufacturing company?
Rent for factory space
ExplanationRent for factory space is a fixed cost for a manufacturing company, as it does not vary with production levels in the short run.
#15
What is the shutdown point for a firm?
The point where price equals average variable cost
ExplanationThe shutdown point is where a firm decides to cease operations when the price falls below the average variable cost.
#16
In the long run, a firm will exit a market if:
Price is less than average total cost
ExplanationFirms will exit a market in the long run if the price is insufficient to cover the average total cost of production.
#17
What is the relationship between marginal cost and average total cost when average total cost is decreasing?
Marginal cost is less than average total cost
ExplanationWhen average total cost is decreasing, marginal cost is lower than average total cost.
#18
In the long run, a firm will enter a market if:
Price is greater than average total cost
ExplanationFirms will enter a market in the long run if the price exceeds the average total cost of production.
#19
What is the relationship between marginal cost and average total cost when average total cost is increasing?
Marginal cost is greater than average total cost
ExplanationWhen average total cost is increasing, marginal cost is higher than average total cost.
#20
What is the relationship between marginal cost and average total cost when marginal cost is below average total cost?
Marginal cost is less than average total cost
ExplanationWhen marginal cost is below average total cost, the latter is decreasing.
