Suppose that you own a monopolistically competitive firm. Using the three-step method, calculate whether your company is making economic profits, economic losses, or zero profits. Use hypothetical numbers for your calculations. Do not use examples or numbers from the text.

What will be an ideal response?


Examples will vary, but should show a thorough understanding of how to calculate a firm’s economic status using the three-step method. For example, a firm’s marginal revenue and marginal cost could intersect at a quantity of 200. Therefore, q* equals 200. At q*, the market price (P*) is $10. Thus, the total revenue is $2,000 (200 x $10 = $2,000). Finally, at q*, the average total cost (ATC) is $8. As a result, total cost is $1,600 (200 x $8 = $1,600). The firm is making a profit of $400 because the total revenue of $2,000 exceeds the total cost of $1,600 by $400.
