Consider a firm with production function is Q=L(28-L. Note that for this production function MPL=28-2L. Since there is only one input here, you can consider that this firm does not use capital or that the production function given is for a fixed level of capital in the short run). Now suppose this firm is perfectly competitive in both labour and product markets, with wage w=$'| 3 and product price p=$1.14. A. (Notes upload) Profit is revenue minus cost. Write an expression for this firm's revenue and for this firm's cost. Be sure to epresent them as functions of the variable L (make substitutions as needed). Give a formula for this firm's MRPL and write the conditions for this firm's profit-maximizing amount of labour. B. For this firm, the marginal cost of labour is equal to . The slope of this firm's MRPL curve is C. This firm will choose L"= .This firm's maximized profit is equal to $ .At L*+'l this firm's profit is at L* (Enter 1 for "higher than", 0 for "equal to", -'l for "lower than", 3 for "not comparable to"). D. The firm's value marginal product of labour if it employs L* units of labour is and its marginal revenue product of labour is
