A purely competitive nut and bolt manufacturer faces a market price of $7.00, an average total cost of $7.50, an average variable cost of $6.00, and a marginal cost of $6.75. Should this firm expand output, contract output, or shut down in the short-run? Use a graph to illustrate your answer, making sure to indicate these price and cost values
Ans) In Perfectly competitive market, price is equal to marginal revenue. And firm produces the quantity where MR and MC curve intersect. If MR is more than MC, firm should expand the production. If MC is more than MR, firm should reduce its production.
Further, if price is above ATC, firms earn positive economic profit. If price is below ATC but above AVC, firms are earning negative economic profit but will continue producing in short run. And if price is below AVC, firm will shutdown.
Here, we see that MR is more than MC and hence firm should expand its production to reach the profit maximising quantity. (Red line is optimal point, blue line is showing current situation)
