Golda Rush quit her job as a manager for Home Depot to start her own hair dressing salon, Goldilocks. She gave up a salary of $40,000 per year, invested her savings of $30,000 (which was earning 5 percent interest) and borrowed $10,000 from a close friend, agreeing to pay 5 percent interest per year. In her first year, Golda spent $18,000 to rent a salon, hired a part-time assistant for $12,000 and incurred another $15,000 in expenses on equipment and hairdressing material. Based on this information, what is the amount of her implicit costs

Which of the following equations is correct

AFC + AVC = ATC

Which of the following is a reason why a firm would experience diseconomies of scale

As the size of the firm increases it becomes more difficult to coordinate the operations of its manufacturing plants

Refer to the diagram to the right. Identify the curves in the diagram

E = marginal cost curves, F = average total cost curve, G = average variable cost curve, H= average fixed cost curve

If the marginal cost curve is below the average variable cost curve, then

average variable cost is decreasing

Which of the following statements best describes the economic short run

If it is a period during which at least one of the firm's inputs is fixed

Which of the following explains why the marginal cost curve has a U shape

Initially, the marginal product of labor rises, then falls

Refer to the diagram to the right. Identify the minimum efficient scale of production

Qb

Refer to the diagram to the right. The vertical difference between curves F and G measures

average fixed costs

Marginal cost is the

additional cost of producing an additional unit of output

Refer to the diagram to the right. Diminishing returns to labor set in

after L1

If production displays economies of scale, the long run average cost curve is

downward sloping

Economic cost of production differ from accounting costs in that

economic cost adds the opportunity cost of a firm using its own resources while accounting cost does not

If, when a firm doubles all its inputs, its average cost of production decreases, then production displays

economies of scale

The average total cost of production

equals cost of production divided by the level of output

Which of the following is an implicit cost of production

rent that could have been earned on a building owned and used by the firm

The law of diminishing marginal returns states

that at some point, adding more of a variable input to a given amount of a fixed input, will cause the marginal product of the variable input to decline

Refer to the diagram to the right. Diminishing marginal productivity sets in after

the 2nd worker is hired

The marginal product of labor is defined as

the additional output that results when one more worker is hired, holding all other resources constant

Refer to the diagram to the right. The curve labeled "E" is

the marginal product curve

Refer to the diagram to the right. The average product of labor declines after L2 because

the marginal product of labor is below the average product of labor

The production function shows

the maximum output that can be produced from each possible quantity of inputs

The basic activity of a firm is

to use inputs to produce outputs of goods and services
