Review Questions – Chapter 22 ( 7) - The Competitive Firm
(1) George is the owner operator of Boy George’s Flower Shop. Last year George earned $100,000 in total revenue. His explicit (accounting) costs were $60,000 paid to his employees and suppliers. During the course of the year he received three offers to work for other flower shops with the highest offer being $40,000 per year. Calculate George’s accounting and economic profit.
(a) Accounting profit = $40,000; economic profit = $0.
(b) Accounting profit = $60,000; economic profit = $40,000.
(c) Accounting profit = $40,000; economic profit = negative $20,000.
(d) Accounting profit = $0; economic profit = negative $40,000.
(2) An essential characteristic of a perfectly competitive firm is that:
(a) it is a price maker.
(b) it is a price taker.
(c) successfully raise its price above market price and potentially increase total revenue if the demand curve is inelastic.
(d) each firm’s demand curve is perfectly inelastic.
(3) In making a production (short term) decision, an entrepreneur:
(a) decides whether to enter or exit the market.
(b) determines what level of output will maximize profits.
(c) determines the level of investment in plant and equipment.
(d) can change both fixed and variable inputs.
(4) Which of the following is generally a fixed cost?
(a) Lease payments for plant and equipment.
(b) Payroll taxes.
(c) Profit taxes.
(d) All the above.
(5) If the firm is producing at a rate of output for which Marginal Cost exceeds price:
(a) the firm must have an economic loss.
(b) the firm can increase its profit by increasing output.
(c) the firm can increase its profit by decreasing output.
(d) the firm is maximizing profit.
