Bagel restaurant is likely to be a constant industry because it is in the perfect competition industry. Bagel restaurant is in the perfect competition industry because there are few entry barriers in this industry. Anyone could enter this industry.
In the short-run, existing firms might get profit just as the case of George’s bagel chain. However, in the long-run, the profit attracts new competitors into this industry, causing price competition. Because each firm will produce at the point where P=LRMC, the price competition will force each firm to produce at the lowest point of the LRAC curve. Thus, each firm in the bagel industry faces the same cost which equals to the price of the bagel, meaning that bagel restaurant is in a constant cost industry.
To maximize profit, firms have to produce at the point where P=LRMC. Supply curve shows the corresponding quantity at any given price. Thus, LRMC is the long-run supply curve for each firm. For firms in the constant cost industry, they face a constant LRMC, which implies that the slope of the long-run supply curve is zero. By contrast, increasing cost industry face increasing LRMC curve, which implies that the slope of the long-run supply curve is positive.

Firms that can produce at lower price are those who have lower MC. Lower MC usually implies that these firms hold some superior factors that other firms don’t have. It seems that firms with superior factors can make economic profits. However, other firms will compete for these superior factors in order to also produce at lower cost, which increase the opportunity cost of holding these superior factors. Thus, firms with lower MC can’t make economic profit because the producer surplus from lower MC has been used to acquire the superior factors.

2) George has the opportunity to acquire the superior asset
