(The Short-Run Firm Supply Curve) Each of the following situations could exist for a perfectly competitive firm in the short run. In each case, indicate whether the firm should produce in the short run or shut down in the short run, or whether additional information is needed to determine what it should do in the short run.

The total cost exceeds total revenue at all output levels.
The total variable cost exceeds total revenue at all output levels.
Total revenue exceeds the total fixed cost at all output levels.
Marginal revenue exceeds marginal cost at the current output level.
Price exceeds average total cost at all output levels.
The average variable cost exceeds the price at all output levels.
The average total cost exceeds the price at all output levels.

Expert Solution

In short run a firm should shut down when it failed to recover its variable cost i.e. Total revenue(TR) < Total Variable Cost(TVC) or Price(P) < Average Variable Cost(AVC) and should produce when TR > TVC or P > AVC

(i) The total cost exceeds total revenue at all output levels.

With the above information we cannot confirm whether P > AVC or TR > TVC or not. Thus we need more information.

(ii) The total variable cost exceeds total revenue at all output levels.

As TVC > TR, thus he should shut down.

(iii) Total revenue exceeds the total fixed cost at all output levels.

With the above information we cannot confirm whether P > AVC or TR > TVC or not. Thus we need more information.

(iv) Marginal revenue exceeds marginal cost at the current output level.

To confirm whether he should shut down or produce we need information regarding P and AVC which is not provided. Hence we need more information.

(v) Price exceeds average total cost(ATC) at all output levels.

It is given that P > ATC and as ATC(= AVC + AFC) > AVC => P > ATC > AVC => P > AVC.

Hence he should produce.

(vi) The average variable cost exceeds the price at all output levels.

As AVC > P, thus he should shut down.

(vii) The average total cost exceeds the price at all output levels.

It is given that ATC > P but we cannot confirm whether AVC > P or not. Thus we need more information.

The short-run supply curve for a firm in a perfectly competitive industry is: The short-run marginal cost curve that is above minimum average variable cost (which takes into account the fact that the firm should shut down if price falls below average variable cost). The entire average variable cost. The entire short-run marginal cost curve. The entire average total cost curve. Which of the following statements is true regarding short-run and long-run costs? (Assume all cost curves have typical shapes,...

Consider a perfectly competitive market that is currently in a short-run equilibrium, and where each firm in the market is making strictly positive profits. Each firm in the market is using a technology called the type A technology. Suppose that the type A technology is available in some finite number. Passed some threshold, new firms that would enter the market would have to use the type B technology, a different (and inferior) technology. The type B technology results in a...
