Use your own language to explain that short run supply curve by a price-taking firm is the positively-sloped portion of the short-run marginal cost curve.

Answer #1

Consider the diagram above

The firm in the perfect competitive market sets P=MC for profit maximization

It will only produce if the price is equal to or greater than minimum AVC because in the short run, only variable cost matters and as long as the firm is able to recover its variable costs, it will keep producing in the short run.

The point S on the graph above shows the minimum AVC point which is also known as the shutdown point because below this point,the firm will not produce and choose to shut down.

In this case, the line S-S2 becomes the supply curve of the perfect competitive firm in the short run as the firm will set P=MC and produce at any price between these two points.

The short run supply curve by a price-taking firm is the positively-sloped portion of the short-run marginal cost curve because the fixed cost of the firm is going to remain equal even if there is no production, which means that the best decision is to not produce anything if the best positive output gives you a loss greater than the fixed cost, and otherwise to produce y. Thus, the best action to take is to produce nothing if the price...

Which of the following statements is correct? a. The positively sloped portion of a price-taking firm’s short-run marginal cost curve, above its point of minimum short-run average variable cost, is this firm’s short-run supply curve. b.

A. In the competitive model, the short-run supply curve of a firm is its marginal cost curve (above minimum average variable cost) and the market supply curve is the horizontal summation of those marginal cost curves across all firms. Since marginal cost curves are upward-sloping, short-run supply curves must also be upward-sloping. Why – what is it that causes marginal cost curves to be upward-sloping in the short-run? (6)

Why is the short-run supply curve for a perfectly competitive firm not equivalent to the entire marginal cost curve? a. Because prices below the minimum variable cost curve cause the firm to shut down. b. Because prices above the minimum variable cost curve cause the firm to shut down. c. Because prices equal to the marginal cost curve cause the firm to shut down. d. Because prices below the marginal cost curve cause the firm to shut down.

T/F - The area under the marginal cost curve measures total variable costs. Why is the short run average cost curve tangent to the long run average cost curve at a level of output? Why does the supply curve of a firm must be in the positively sloped part of the MC curve and not in the negatively sloped part? In the long run, why is the long run industry supply curve flat at min(AC)?
