Economic profits may be positive, zero, or negative. If economic profit is positive, other firms have an incentive to enter the market. If profit is zero, other firms have no incentive to enter or exit. When economic profit is zero, a firm is earning the same as it would if its resources were employed in the next best alternative. If the economic profit is negative, firms have the incentive to leave the market because their resources would be more profitable elsewhere. The amount of economic profit a firm earns is largely dependent on the degree of market competition and the time span under consideration.
