When the MC is smaller the AC, the AC decreases. This is because when the extra unit of output is cheaper than the average cost then the AC is pulled down. Similarly, when the MC is greater than the AC, the AC is pulled up. The point of intersection between the MC and AC curves is also the minimum of the AC curve.

When AR MR MC AC The firm will get which profit?

3) Normal Profits: Normal profits are earned when the firm is producing where AC = AR. A firm must earn at least Normal Profits if it is to stay in business in the long run. 1) Equilibrium: Occurs at point E where MC = MR and MC is rising and cuts MR from below.

How does a competitive firm determine its profit-maximizing level of output?

The profit-maximizing choice for a perfectly competitive firm will occur at the level of output where marginal revenue is equal to marginal cost—that is, where MR = MC. This occurs at Q = 80 in the figure.

How is ATC calculated in perfect competition?

One is to calculate ATC = 50/q+4+2q, set q=4, and find ATC=24.5, so price is less than ATC, by 4.5, and they are selling 4, so the losses are 18. Another way is to calculate this is to calculate total revenue (P*Q=80) minus total cost 50+16+32=98 and see the difference is -18 (or a loss of 18).

Where does MC cut AC below?

The fall is due to the economies of scale. But beyond a point (M), i.e., when output is expanded too much, both AC and MC start rising and now MC is above AC, i.e., the marginal cost is greater than the average cost. That is why MC cuts AC from below at its lowest point.

How do you profit from perfect competition?

In order to maximize profits in a perfectly competitive market, firms set marginal revenue equal to marginal cost (MR=MC). MR is the slope of the revenue curve, which is also equal to the demand curve (D) and price (P). In the short-term, it is possible for economic profits to be positive, zero, or negative.

What is minimum ATC?

If we have P > min(ATC), there are profit opportunities, new firms would enter, and market forces will push down the price until P = min(ATC). If we have P < min(ATC), firms are making losses, firms would exit, and market forces will push up the price until P = min(ATC).

When MC is equal to AC the slope of AC is?

(iii) When the slope of AC is equal to zero (i.e., AC is minimum), MC is equal to AC. Therefore, MC cuts AVC and AC from below at their respective minimum points.

How does AC behave when AVC rises?

Answer:So, AC must fall. AVC starts rising after OQ1 output is being produced; its rise over a certain range is offset by a fall in AFC. That is why AC continues to fall over that range of output even if AVC rises.
