If a competitive firm's marginal cost curve is U-shaped, then:

A) its short-run supply curve is U-shaped too
B) its short-run supply curve is the downward-sloping portion of the marginal cost curve
C) its short-run supply curve is the upward-sloping portion of the marginal cost curve
D) its short-run supply curve is the upward-sloping portion of the marginal cost curve that lies above the short-run average variable cost curve
E) its short-run supply curve is the upward-sloping portion of the marginal cost curve that lies above the short-run average total cost curve

Marginal Cost Curve

A graphical representation showing how the cost of producing one more unit of a good changes as the production volume is increased.

Short-Run Supply

The total quantity of goods and services that producers are willing and able to sell at a given price in the short term, considering some inputs as fixed.

U-Shaped

Describes the shape of certain graphs, such as average cost curves in economics, indicating a period of declining costs followed by increasing costs as output rises.

  • Acquire knowledge about the concept of marginal cost and its critical importance in determining a firm's production and supply choices.

Final Answer :
D
Explanation :
In the short run, a firm's supply curve is determined by comparing the market price to its marginal cost. Since the marginal cost curve is U-shaped, the portion that lies above the short-run average variable cost curve is the portion where the firm is willing to produce output to supply the market at the given price. Therefore, the short-run supply curve for a competitive firm with a U-shaped marginal cost curve is the upward-sloping portion of the marginal cost curve that lies above the short-run average variable cost curve, which is answer choice D.
