Which of the following conditions is true when a producer minimizes the cost of producing a given level of output?
  • The marginal product per dollar spent on all inputs is equal

Which of the following “costs” could a firm that wants to remain in business avoid if it halted current production?

  • Variable costs
If a firm’s production function is Leontief and the price of capital goes down the
  • Cost minimizing combination of capital and labor does not change

Suppose the production function is given by Q = 4K + 6L. What is the average product of capital when 10 units of capital and 5 units of labor are employed?

  • 7

Suppose the production function is given by Q = 2K + 5L. What is the marginal product of labor when 15 units of capital and 10 units of labor are employed?

  • 5

Suppose the production function is Q = min {3K, L}. How much output is produced when 6 units of labor and 3 units of capital are employed?

  • 6

Suppose the marginal product of labor is 10 and the marginal product of capital is 8. If the wage rate is $5 and the price of capital is $2, then in order to minimize costs the firm should use

  • More capital and less labor
Suppose the long-run average cost curve is U-shaped. When LRAC is in the increasing stage, there exist
  • Dis economies of scale

The long-run average cost curve defines the minimum average cost of producing alternative levels of output, allowing for optimal selection of

  • All factors of production

When there are economies of scope between products, selling off an unprofitable subsidiary could lead to

  • Only a minor reduction in costs

When there are economies of scope between two products which are separately produced by two firms, merging into a single firm can

  • Accomplish a reduction in costs
Cost complementary exits in a multi-product cost function when
  • The marginal cost of producing one output is reduced when the output of another product is increased
