A firm will shut down in the long run if its earning is less than normal profit. In economics, normal profit refers to the minimum level of profit necessary to keep a firm in business in the long run.

If a firm's earning is less than this level of profit in the long run, it is not covering all of its costs and will eventually go out of business. Therefore, a firm will shut down if its earning is less than normal profit, as it cannot sustain its operations in the long run.
