Refer to Figure 8.6, which shows just three of a firm's various possible short-run average cost curves. Suppose the firm is currently producing 160 units at an average cost of $90 per unit. Which of the following statements is true? $/unit 200 175 150 90 80 R 50 50 O ACI AC2 X 160 130 AC3 Output Figure 8.6 The firm could reduce its short-run average cost by producing less output. The firm is producing the level of output that minimizes short-run average cost. The firm is producing its output at the lowest possible long-run average cost. The firm could reduce its short-run average cost by producing more output.

Economics Question
A firm has a fixed production cost of $1,000 and a constant marginal cost of production of $700 per unit produced. What is the firm's total cost function? O A. TC = 1,000 + (700q) O B. TC = 1,000 + (700q). OC. TC = 700q. O D. TC = 1,000. The firm's average total cost (ATC) of production is O A. ATC = 1,000 + (700q). OB. 1,000 + (700q) ATC = Oc. 1,000 ATC = O D. ATC = 700q. O E. ATC = 700. If the firm wanted to minimize the average total cost, would it choose to be very large or very small? Explain. OA. very small because the average total cost of production rises with output. O B.- very large because the average variable cost of production falls with output. OC. very small because the average fixed cost of production rises with output. O D. very small because the total cost of production rises with output. O E. very large because the average total cost of production falls with output.
on the long run average cost curve can you mark where this would be on the curve?
Which of the following best explains why a firm would not stop producing if the loss is less than its fixed costs? O Fixed costs are paid regardless of whether something or nothing is produced, and the firm receives enough revenue per unit to cover ATC and some MC. O Fixed costs are paid regardless of whether something or nothing is produced, and the firm receives enough revenue per unit to cover ATC and some FC. O Fixed costs are paid regardless of whether something or nothing is produced, and the firm receives enough revenue per unit to cover AVC and some FC. O Fixed costs are paid regardless of whether something or nothing is produced, and the firm receives enough revenue per unit to cover AVC and some MC.
Suppose we have a firm in a perfectly competitive market. Assume that we have the usual shaped cost curves. At a market price of $15 the profit maximizing firm produces 53 units. Something changes that causes the firm to produce a quantity of zero at a price of $15 in the short-run. Which of the changes below can explain the change in the firm's behavior? O An increase in the fixed cost and a decrease in the marginal cost. O An increase in the fixed cost. O An increase in the marginal cost. O A decrease in the market price.
4) Suppose that a firm's production function is Q = Lº.4K0.6. The cost of a unit of labor is $8 and the cost of a unit of capital is $12. Write firm's long run cost function. Calculate the slope of isocost line. Calculate marginal rate of technical substitution. d. Suppose firm decides to produce 50 units, what is the cost minimizing combination of these two resources (labor and capital)? a. b. C.

In which of the following cases is it most likely that the firm's curves will shift leftward to MC 2 and ATC 2? O a. The market price of peanuts decreases. O b. The market price of peanuts increases. O c. The government lowers taxes paid by peanut butter producers. O d. The market price of peanuts remains constant.

A firm's production function takes the form: Q(L, K) = min {8L, 6K}, where Q represents output and L and K represent labour and capital, respectively and where w and r give the prices of labour and capital. What would be the expression for the firm's marginal costs? O O O O MC = w + 1/ MC = 6r + 8w MC = W MC 6w+8r W MC = 8 +! 6 + 3r 6w+8r = Q (²= ² + ² )
