As we continually increase labour one unit at a time,
(a) the addition to output will become larger, if capital is held constant.
(b) the addition to output will become smaller, if capital is held constant.
(c) larger reductions in capital will be required to keep output constant.
(d) smaller reductions in capital will be required to keep output constant.
(e) larger increases in labour will be required to keep output constant.
QUESTION 11
The least cost technique of producing a given output occurs where the marginal rate of substitution of labour for capital equals the
(a) ratio of the quantity of labour used relative to the quantity of capital used.
(b) ratio of the price of labour to the price of capital.
(c) minimum point on the isoquant line.
(d) marginal cost of capital
(e) ratio of the marginal cost of capital to the marginal cost of labour.
QUESTION 12
A perfectly competitive firm’s supply curve is the upward-sloping part of its
(a) average product curve, at all points above the point of minimum average variable cost.
(b) marginal cost curve, at all points above the point of minimum average fixed cost.
(c) marginal revenue curve, at all points above the point of minimum average revenue.
(d) marginal revenue curve, at all points above the point of minimum average total cost.
(e) marginal cost curve, at all points above the point of minimum
Into which of the three elements of manufacturing cost would each of the following be classified?
(Again, so far, remember that pricing in this case is set at the marginal cost level.)
Explain what action a profit maximizing firm takes if marginal revenue is greater than marginal cost:
3. Using the variable costing method, which of the following costs are assigned to inventory?
The difference between the present value of an investment?s future cash flows and its initial cost is the:
1) If a firm in a purely competitive industry is confronted with an equilibrium price of $5, its marginal revenue:
The marginal cost function intersects the average fixed cost function where the average variable cost function is a minimum.
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
1) The system achieves the balance between two costs ordering cost and the carrying cost.
representative cost mix that is proportional to total revenues. Hence, we use the average COGS
average cost. In the short-term, it may be acceptable to price below AC if this price exceeds
AC(Q): average cost function; describes how the firms average cost function or per unit of output costs vary with the amount of output it produces. When average costs decreases as output increases, there are economies of scale
3. Assume that cost of goods sold for a company consists only of variable costs and gross margin is = (revenue – cost of goods sold)/revenue. Which of the following is true
complex. The basic objective here is that of taking the cost of expected production operations in the
