The amount that a firm pays for all of the inputs that go into producing goods and services is the: O average cost. O total revenue. O total price. O total cost.

To economists, the main difference between the short run and the long run is that: the law of diminishing returns applies in the long run, but not in the short run.B. in the long run all resources are variable, while in the short run at least one resource is fixed.C. fixed costs are more important to decision making in the long run than they are in the short run.D. in the short run all resources are fixed, while in the long run all resources are variable.

The following is a table of cost for a toy manufacturing firm. The variable input is labor. Use this table to answer the following question. Average variable Average fixed cost Average Variable Quantity of toys Total costs cost total cost costs $0 $20 $10 A $40 В In the cell B, which number is correct? 10 O 5 none of these options is correct O 15

A is the total cost curve, B is the marginal cost curve, and C is the total fixed cost curve. O B. A is the average variable cost curve, B is the total fixed cost curve, and C is the average total cost curve. O C. A is the total cost curve, B is the total variable cost curve, and C is the total fixed cost curve. O D. A is the total cost curve, B is the total variable cost curve, and C is the marginal cost curve. O E. A is the average variable cost curve, B is the average total cost curve, and C is the marginal cost curve. Quantity с

1. Which of the following statements is true? a. the cost of producing output in the short run is always strictly less than the cost of production in the long run b. the cost of producing output in the short run is always strictly greater than the cost of production in the long run c. the cost of producing output in the short run is greater than or equal to the cost of production in the long run d. the cost of producing output in the short run is less than or equal to the cost of production in the long run

4. The shape of a firm's long-run average cost curve depends o how costs vary with scale of operation. Draw a long-run average cost curve for a firm that exhibits economies of scale, constant returns to scale, and diseconomies of scale. Identify each of these sections of the cost curve and explain why each section exemplifies its specific type of return to scale.

4 No production in the short-run and positive production in the long-run Suppose that the marginal cost curves in the short-run and in the long-run are identical for a certain firm, and that the short-run average cost curve is below the long-run average cost curve. Then for a certain price, we can show that the firm wants to produce in the short-run, but not in the long-run. In this question, we will investigate whether a reversed situation is possible. Consider the following production function: Q = L³K². The wage for labor (L) is w = 1. The cost of using capital (K) has two parts: the first is the rent that the firm needs to pay capitalists (r = 2), and the second is the maintenance cost (m = 2). The firm can change labor and capital in the long-run, but it can change only labor in the short-run. Thus, the long-run economic cost with (L,K) is wL+ (r+m)K, while the short-run economic cost of running the firm is wL + mko for given capital Ko. (Here we are implicitly assuming the…
