The diagram below shows demand and cost curves for a monopolistically competitive firm.
FIGURE 11-4

◦ expand its output in the long run.
◦ be making profits and new firms would enter the industry in the long run.
◦ be making losses and some firms would exit the industry in the long run.
◦ decrease costs in order to break even at P
1 and Q
1 in the long run.
◦ increase costs in order to break even at P
1 and Q
