A decrease in the price of a productive resource will result in each of the following except a(n): A.Downward shift in the average-cost curves for all products which use the resourceB. Increase in the quantities produced and sold of all products which use the resourceC. Rightward shift in the demand curves for all products which use the resourceD. Increase in the quantity demanded of this productive resource

3. (14 points) Let the production function be Q(K,L)=2K L. The cost of one unit of labor is w, the cost of one unit of capital is r, and the quanitity to produce is y. (a) (4 points) Set up the firm's cost-minimization problem, and clearly write down the con- Page 6 straint the firm faces. The cost minimization problem of the firm is min(KL) WL+rK. The constraint: y=2K!L!. anscribed Text (b) (5 points) What are two conditions that the optimal bundle L and K need to satisfy? Write down their expressions. Tangency: -=-; production: y = 2(K)! (L)!. (c) (5 points) Solve for the optimal bundle of L. and K that minimizes the firm's cost at y=144 by finding L and K", assuming that w $16 and r $81. By solving the system of two conditions in Part (b), it should be not that hard to get L = 162 and K* = 32.

I don’t think I’m understanding the question. Could I have an explanation of the mode to solve it?

Cost (dollars) 150 100 50 0 5 10 D $15 20 B Output (teapots per day) 5. Refer to Figure above. Which one of the following statements are [TRUE/FALSE]? 0 A. The vertical gap between curves B and C is equal to average variable cost. [TRUE/FALSE] 0 B. Average fixed cost decreases with output. [TRUE/FALSE] 0 C. Line B comes closer to line C as output increases because of a decrease in average fixed cost. [TRUE/FALSE] D. The vertical gap between curves B and C is equal to average fixed cost. [TRUE/FALSE] 0 E. Curve D is the marginal cost curve. [TRUE/FALSE]

Lump-Sum Tax The city government is considering two tax proposals: • A lump-sum tax of $300 on each producer of hamburgers. • A tax of $1 per burger, paid by producers of hamburgers. please help

Suppose a firm is currently producing 500 computers per week and charging a price of $1,000. What happens to the firm's inventory of computers if there is a negative demand shock and prices are inflexible? Multiple Choice The firm's inventory will increase by 200 computers per week. The firm's inventory will not change. The firm's inventory will decrease by 150 computers per week. The firm's inventory will increase by 350 computers per week. rch 99+ Price Price

13. Firms in Competitive Markets The market for fertilizer is perfectly competitive. Firms in the market are producing output but are currently making economic losses. Which of the following statements is true about the price of fertilizer? Check all that apply. The price of fertilizer must be less than average total cost. Price and Costs The price of fertilizer must be less than marginal cost. The price of fertilizer must be equal to average variable cost. The following graphs show the cost curves faced by a typical firm, the demand for fertilizer, and possible price and supply curves. MC Firm ATC LAVC II II Quantity (?
