The marginal revenue curve of a monopoly crosses its marginal cost curve at $30 per unit and an output of 2 million units. The price that consumers are willing to pay for this output is $40 per unit. If it produces this output, the firm's average total cost is $43 per unit, and its average fixed cost is $8 per unit. What is the profit-maximizing (loss-minimizing) output? What are the firm's economic profits (or economic losses)?
