If price falls in the zone between the shutdown point and the break even point, then the firm is making losses but will continue to operate in the short run, since it is covering its variable costs, and more if price is above the shutdown-point price. If the price falls exactly on the zero profit point where the MC and AC curves cross, then the firm earns zero profits.
For every subject you can now access each digital resource as soon as it is ordered. The question we want to continue with is when should a firm shutdown?
