question
What are the basic activity of a firm?
answer
-Labor(L)
-Capital(K)
-Natural resources(N)
-The produce outputs(Q)
-Capital(K)
-Natural resources(N)
-The produce outputs(Q)
question
Technology
answer
the processes a firm uses to turn inputs into outputs of goods and services
question
production function
answer
Is the relationship between the inputs employed by a firm and the Maximum output(Q)
question
Produce Outputs formula:
answer
Q=F(L,K)
question
What are the two time frames that firms use?
answer
-Short run
-Long run
-Long run
question
Short run
answer
Is a time frame in which the quantity of at leas one of a firm's used in production is fixed.
question
Long run
answer
The long run is a time frame in which the quantities of all inputs can be varied.
question
Total product
answer
Is the total output produced in a given period.
question
Marginal product
answer
Is the increase in output that arises from an additional unit of labor employed, with all other inputs remaining the same.
question
Average product
answer
is equal to total product divided by the quantity of labor employed.
question
When does the firm experience Increasing marginal returns?
answer
From increased Specialization and division of labor.
question
When does the firm experience Diminishing marginal returns?
answer
Because each additional worker has less access to capital and less space to work.
question
Three Costs concepts:
answer
-Total cost
-Marginal cost
-Average cost
-Marginal cost
-Average cost
question
Fixed Cost (FC)
answer
Is the cost of the firm's inputs. Remains constant as output changes.
question
Variable Cost (VC)
answer
is the cost of the firm's variable input. Changes as output changes.
question
Total Cost (TC)
answer
Is the cost of all inputs a firm uses in production.
question
Total cost formula:
answer
TC = TFC + TVC
question
Marginal cost
answer
is the increase in total cost that results from a one-unit increase in total product.
question
Marginal cost formula:
answer
MC = change in TC / change in Q
question
Average fixed cost (AFC)
answer
is total fixed cost per unit of output
question
Average variable cost (AVC)
answer
is total variable cost per unit of output
question
Average total cost (ATC)
answer
is total cost per unit of output.
question
Average total cost (ATC) Formula:
answer
ATC = AFC + AVC
question
long-run average cost (LRAC)
answer
shows the lowest cost at which a firm is able to produce a given quantity of output in the long run, when no inputs are fixed.
question
Economies of scale
answer
features of a firm's technology that lead to falling long-run average cost as output increases.
question
Diseconomies of scale
answer
features of a firm's technology that lead to rising long-run average cost as output increases.
question
Constant returns to scale
answer
features of a firm's technology that lead to constant long-run average cost as output increases.
question
Minimum efficient scale
answer
is the smallest quantity of output at which the long-run average cost reaches its lowest level.
