Which of the following is a fixed cost?

Raw materials

Labor

Rent for the factory

Electricity bills

What is the primary factor that distinguishes short-run production from long-run production?

The level of technology

The duration of the production period

The availability of raw materials

The size of the firm

What is the key feature of the short-run production function?

All inputs are variable.

All inputs are fixed.

Some inputs are variable, while others are fixed.

All inputs are perfectly elastic.

In the short run, what happens to a firm's fixed costs as production increases?

Fixed costs increase.

Fixed costs decrease.

Fixed costs remain constant.

Fixed costs become variable.

What is the formula for calculating average variable cost?

Total Variable Cost / Quantity of Output

Total Cost / Quantity of Output

Total Fixed Cost / Quantity of Output

Total Cost - Total Fixed Cost

In the short run, a firm's average total cost curve may be U-shaped due to which phenomenon?

Economies of scale

Diseconomies of scale

Diminishing marginal returns

Constant returns to scale

What is the relationship between marginal cost and average variable cost?

Marginal cost is always greater than average variable cost.

Marginal cost equals average variable cost at the minimum point of the average variable cost curve.

Marginal cost is always less than average variable cost.

Marginal cost and average variable cost are unrelated.

In the long run, firms may experience increasing returns to scale when:

Inputs are increased proportionately.

Inputs are increased more than proportionately.

Inputs are decreased.

Inputs are kept constant.

What is the law of diminishing marginal returns?

As the quantity of a variable input increases, the marginal product of that input decreases.

As the quantity of a variable input increases, the marginal product of that input remains constant.

As the quantity of a variable input increases, the marginal product of that input increases exponentially.

As the quantity of a variable input increases, the marginal product of that input increases linearly.

#10

What is the difference between explicit and implicit costs in economics?

Explicit costs are fixed, while implicit costs are variable.

Explicit costs involve actual cash payments, while implicit costs do not.

Explicit costs are opportunity costs, while implicit costs are accounting costs.

Explicit costs are associated with variable inputs, while implicit costs are associated with fixed inputs.

#11

Which cost is relevant for short-term decision-making, such as whether to continue or discontinue a product line?

Sunk cost

Fixed cost

Marginal cost

Opportunity cost

#12

When does a firm experience economies of scale?

When average total cost decreases as output increases.

When average total cost increases as output increases.

When average variable cost is minimized.

When average fixed cost is minimized.

#13

What is the difference between short-run and long-run production costs?

Short-run costs include fixed and variable costs, while long-run costs only include variable costs.

Short-run costs only include variable costs, while long-run costs include both fixed and variable costs.

Short-run costs are incurred for a specific period, while long-run costs are incurred over an extended period.

There is no difference between short-run and long-run production costs.

#14

What is the main objective of cost minimization for a firm?

Minimizing total cost

Minimizing variable cost

Minimizing fixed cost

Minimizing average cost
