when an isocost line is just tangent to an isoquant, we know that
all of the above -the output is being produced at minimum cost -the ratio of marginal products are equal to the ratio of the input prices -MRTS=-w/r
in the short-run, the marginal cost is rising and the average variable cost is falling as output is increased. thus
marginal cost is below average variable cost
For the production function q=f(L,K)=3L+K, the marginal rate of technical substitution (MRTS)
remains constant as the firm substitutes labor for captal
the marginal rate of technical substitution always equals
the ratio of marginal products of inputs
suppose that capital and labor must be kept in a fixed proportion to produce a particular good. for example, digging a trench requires one worker who has one shovel. what does this imply about returns to scale?
there are constant returns to scale
if an isocost line crosses the isoquant twice, a cost minimizing firm will
us a different isocost line to select the bundle of points
suppose a firm's production function is q=f(L,K)=L^1/3 K^1/3. This firm's cost functions exhibits
diseconomies of scale
suppose the marginal revenue from the next unit of output is smaller that the marginal cost of producing it. the firm should
decrease the production level
which of the following statements best summarizes the law of diminishing marginal returns
in the short run, as more labor is hired, output increases at a diminishing rate
if there are diseconomies of scale within a given range of output, which of the following is (are) TRUE?
the long-run average curve must be upward sloping within that range of output
