Exam 43: Profit Maximization

The following graph shows the marginal revenue (MR)and marginal cost (MC)curves of an imperfectly competitive firm. Figure 22.2 Refer to Figure 22.2.At a quantity of 10 the firm should _____ , but at a quantity of 75 the firm should _____.

Graphically, total cost is equal to the area of the:

Entry of new firms to the industry lowers the economic profit of the existing firms.

Which of the following is true of marginal cost?

A perfectly competitive firm cannot affect the market price by raising or reducing its supply.

Suppose that at a given level of output, a perfectly competitive firm charges a price of $12 and has average total costs of $10.If its economic profit is $20, 000, then it must be producing:

Goodspeed Automobiles manufactures 100 disc brake cylinders.At this output level, its marginal revenue is equal to its marginal cost.If the revenue per unit of output is $500 and the per unit cost is $350, its profit is:

The figure given below shows the cost curves of a firm. Figure 22.3 ATC: Average Total Cost AVC: Average Variable Cost MC: Marginal Cost In Figure 22.3, what is the total cost of producing 140 units of the output?

The figure given below shows the cost curves of a firm. Figure 22.3 ATC: Average Total Cost AVC: Average Variable Cost MC: Marginal Cost Refer to Figure 22.3.If the firm maximizes profits at 120 units of the output, calculate the firm's marginal revenue.

If marginal revenue is greater than marginal cost, the producer must reduce the level of output to maximize profit.

Accounting profit of a business firm is also called:

The daily vegetable market is an example of oligopoly.

Economic profits is the difference of total revenue and total costs including the opportunity costs of the resources used in the business.

In contrast to both perfect competition and monopolistic competition, an oligopoly market structure is characterized by:

A profit-maximizing firm will produce the level of output at which:

Scenario 22.1 Jane left her job at Siemens and started her own boutique.She used to earn $50, 000 annually at Siemens.She took a loan of $10, 000 and used $20, 000 from her personal savings to begin her venture.She agreed to repay the loan with 10% interest.Her business is bringing in $80, 000 annually.She has rent and labor expenses of $15, 000.Also assume that Jane could have used her own money i.e.$20, 000 to buy stocks in Intel which would have returned 5% to her last year. Refer to Scenario 22.1.Compute Jane's economic profit.

In monopolistic competition there are no brands, all the producers produce only identical, generic products.

Assume that a firm's marginal revenue curve intersects the rising portion of the marginal cost curve at 100 units of output.At this output level, a profit-maximizing firm's total cost is $1, 000.If the price of the product is $3 per unit and the firm produces at the profit-maximizing level, the firm will earn an economic profit equal to:

Which among the following does not determine the shape of the demand curve under different market structures?

The following figure shows the cost and revenue structures of a firm.MC represents the marginal cost curve, AC represents the average cost curve, AR represents the average revenue curve, and MR represents the marginal revenue curve.P* is the equilibrium price and Q* is the equilibrium output. Figure 22.5 Refer to Figure 22.5.Identify the market structure in which the firm operates:
