Problem 1: Short-Run Prot Maximization [10 points] Consider a rm that uses both capital {K} and labour [L] to produce a nal product [C1] that it sells at the market price 55. The rm buys Labour at a cost of $4 per unit and capital at a cost of $10 per unit. The rm is a pricetaker for all prices with the following production function: .9 = 4K1f2L1f2 This production function implies the following: Llfz MPK = 2 Kll'z Kifz MPL = Luz Suppose also that the firm currently has 16 units of capital [K = 15] in the ShortRun. For 0.1 (16, assume that we are operating in the ShortRun: 1. Given the above production function, write down an expression for Labour employed as a function of the quantity produced (Le. L = film]. [1 point] 2. Use the MPL and the wage rate to write down an expression for the Firm's Marginal Cost per unit of output ({1} produced as a function of (1. [3 points] 3. Show that the rm's protmaximizing quantity {431*} is equal to 160 in the shortru n. [1 point] 4. What are the firm's variable costs {VC} and xed costs {FC} at 0.\"? [2 points] 5. What are this rm's shortrun prots in this example? [1 point] 5. What would be the rm's ShortRun prots if it chooses to shut down? Should the rm keep producing in the shortrun? How do you know?
