A firm making profits in the short run will nonetheless only break even in the long run because demand will decrease and average total cost will increase, meaning that in the long run, a monopolistically competitive company will make zero economic profit. This illustrates the amount of influence the company has over the market; because of brand ...
A PC company can make excess profits in the short term but excess profits attract competitors, which can enter the market freely and decrease prices, eventually reducing excess profits to zero. [21] A monopoly can preserve excess profits because barriers to entry prevent competitors from entering the market. [22] Profit maximization: A PC ...
The principal difference between short run and long run profit maximization is that in the long run the quantities of all inputs, including physical capital, are choice variables, while in the short run the amount of capital is predetermined by past investment decisions. In either case, there are inputs of labor and raw materials.
Economic profit can, however, occur in competitive and contestable markets in the short run, since short run economic profits attract new competitors and prices fall. Economic loss forces firms out of the industry and prices rise till marginal revenue equals marginal cost, then reach long run equilibrium.
Suppose Firm A acts as a monopolist. The profit-maximizing monopoly price charged by Firm A is then: = + Since Firm B will never sell below its marginal cost, as long as , Firm B will not enter the market when Firm A charges . That is, the market for good X is an effective monopoly if:

[1] [2] Because a monopoly faces no competition, it has absolute market power and can set a price above the firm's marginal cost. [1] [2] The monopoly ensures a monopoly price exists when it establishes the quantity of the ...
The short run shutdown point for a competitive firm is the output level at the minimum of the average variable cost curve. Assume that a firm's total cost function is TC = Q 3 -5Q 2 +60Q +125. Then its variable cost function is Q 3 –5Q 2 +60Q, and its average variable cost function is (Q 3 –5Q 2 +60Q)/Q= Q 2 –5Q + 60.
