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 con- sumers 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. What is the profit-maximizing (loss-minimizing) output? What are the firm's economic profits (or eco- nomic losses)?
