Joe owns a small coffee shop, and his production function is q = 3KL where q is total output in cups per hour, K is the number of coffee machines (capital), and L is the number of employees hired per hour (labor). If Joe's capital is currently fixed at K=3 machines, what is his short-run production function?
q = 3L
q = 3L2

We manufacturer automobiles given the production function q = 5KL where q is the number of autos assembled per eight-hour shift, K is the number of robots used on the assembly line (capital) and L is the number of workers hired per hour (labor). If we use K = 10 robots and L = 10 workers in order to produce q = 450 autos per shift, then we know that production is:
technologically efficient.
optimal
technologically inefficient.
maximized.
non of the above
Which of the following equations based on capital (K) and labor (L) inputs does not represent a plausible production function?
F(K,L) = 3KL
F(K,L) = 3K
F(K,L) = K + L - 1
F(K,L) = 10(KL)0.5
both b and c
Writing total output as Q, change in output as △Q, total labor employment as L, and change in labor employment as △L, the marginal product of labor can be written algebraically as
ΔQ ∙ L.
Q / L.
ΔQ / ΔL.
ΔL / ΔQ.
both b and d
The marginal product of an input is:
total product divided by the amount of the input used to produce this amount of output.
the addition to total output that adds nothing to total revenue.
the addition to total output that adds nothing to profit.
the addition to total output due to the addition of one unit of all other inputs.
the addition to total output due to the addition of the last unit of an input, holding all other inputs constant.
According to the law of diminishing returns:
the total product of an input will eventually be negative.
the marginal product of an input will eventually be negative.
the marginal product of an input will eventually decline.
the total product of an input will eventually decline.
none of the above
At which point on the total product curve is the average product of labor the highest?
Point A
Point B
Point C
Point D
An isoquant:
must be linear
cannot have a negative slope.
is a curve that shows all the combinations of inputs that yield the same total output.
is a curve that shows the maximum total output as a function of the level of labor input.
is a curve that shows all possible output levels that can be produced at the same cost.
Two isoquants, which represent different output levels but are derived from the same production function, cannot cross because:
isoquants are downward sloping.
additional inputs will not be used by profit maximizing firms if those inputs decrease output.
isoquants represent different utility levels.
this would violate a technical efficiency condition.
both b and d
A construction company builds roads with machinery (capital, K) and labor (L). If we plot the isoquants for the production function so that labor is on the horizontal axis, then a point on the isoquant with a small MRTS (in absolute value) is associated with high ________ use and low ________ use.
labor, capital
capital, labor
concrete, gravel
