an implicit cost

look at the figure long-run and short-run average cost curves. if a firm is producing at point c on the atc2 but anticipated increasing output to 225,000 units in the long run, the firm will build a _ plant and have _ of scale.

bigger; diseconomies

a _ cost is the cost of inputs that increase or decrease with production.

variable

(figure short-run costs) look at the figure short-run costs. c is the _ cost curve.

average variable

a firm was producing 20,000 units of output at the total cost of $40,000. it now produces 30,000 units and the corresponding total cost is $50,000. this firm is experiencing _.

economies of scale

When __________________ exist, doubling of all inputs will result in more than doubling output, which means __________________________________________.

economies of scale; a larger factory can produce at a lower average cost than a smaller company.

increasing

variable inputs refer to _ that can easily be increased or decreased in a _ period.

inputs; short

________________________ arises where many firms are competing in a market to sell similar but differentiated products.

monopolistic competition

at the current level of output, becca furniture's marginal cost curve is above the average total cost curve. this means becca furniture's average total cost curve:

must be rising

as the point where the total cost curve touches the vertical axis

____________________________ occur when the marginal gain in output diminishes as each additional unit of input is added.

diminishing marginal returns

the law of diminishing marginal product days that in the short-run, the marginal product _ at firsts but sooner or later additional workers will have a _ marginal product.

increases; decreasing effect on
