5. How short-run profit or losses induce entry or exit
Fantastique Bikes is a company that manufactures bikes in a monopolistically competitive market. The following graph shows Fantastique's demand
curve, marginal revenue curve (MR), marginal cost curve (MC), and average total cost curve (ATC).
Place the black point (plus symbol) on the graph to indicate the short-run profit-maximizing price and quantity for this monopolistically competitive
company. Then, use the green rectangle (triangle symbols) to shade the area representing the company's profit or loss.
