Question
1. A firm's supply curve for labor: A) is vertical for a firm in perfect competition. B) is the same thing as the MRPL for a firm in perfect competition. C) and the firm's MRPL will determine the profit-maximizing quantity of labor hired by the firm in perfect competition. D) is the same as its demand curve for labor. 2. The wage paid by a firm buying labor in a perfectly competitive market: A) is greater than the market wage. B) is less than the market wage. C) is equal to the market wage. D) increases with the quantity of labor hired. 3. A lower wage: A) has an income effect but not a substitution effect on the quantity of labor supplied. B) means a higher income for any given level of labor supplied. C) has an income effect which is always negative with respect to the quantity of labor supplied. D) has an income effect which is always positive with respect to the quantity of labor supplied. 4. In perfect competition where P is the price of output: A) MRPL = MPL x P. B) MRPL/MPL = PL. C) MRP/P = MPK. D) MRPL x P = MPL. 5. The net present value (NPV) of an activity or project is: A) equal to the future value of all the revenues minus the present value of all the costs associated with it. B) equal to the present value of all the revenues minus the present values of all the costs associated with it. C) equal to the present value of all the revenues minus the future values of all the costs associated with it. D) equal to the future values of all the revenues minus the future values of all the costs associated with it. 6. The condition for hiring factors of production- that is, where MFC = MRP- is analogous to the profit-maximizing output condition: A) TR = TC. B) MR = MC. C) AR = ATC. D) P = MR. 7. A firm should use less of a factor of production if: A) MRP > MFC. B) MRP = MFC C) (MR x MP) < MFC D) MRP < (MP x MR)Explanation / Answer
