16
Q

What is the Law of Marginally Diminishing Returns?

A

Principle that as the use of an input increases, with other inputs fixed, the resulting additions to output will eventually decrease

17
Q

What is the Cobb-Douglas Production Function? Use “a” as a constant.

A

q = a(L^c)(K^d)

18
Q

What is short run?

A

period of time where one input is considered to be fixed.

19
Q

What is long run?

A

period of time where all inputs can be changed

20
Q

What is Marginal Product of Labor? Variable?

A

the change in output that is the result of increasing the amount of labor used by 1 unit; MPL

21
Q

What is the Marginal Product of Labor Function?

A

the change in output for a change in labor while holding other inputs constant. The partial derivative of the production function with respect to Labor

22
Q

What is the Average Product of Labor Function?

A

total product divided by the amount of labor

23
Q

What is Returns to Scale?

A

the change in total output when changing both labor and capital in equal proportions

24
Q

What is Constant Returns to Scale?

A

output changes by the same proportion that labor and capital is changed; c+d = 1

25
Q

What is Increasing Returns to Scale?

A

output changes more than proportion that labor and capital is changed; c+d > 1

26
Q

What is Decreasing Returns to Scale?

A

output changes less than proportion that labor and capital is changed; c+d < 1

27
Q

What is Isoquant?

A

A curve showing all the possible combinations of inputs that yield a given amount of output

28
Q

True or false; Higher levels of output require more of both inputs and move isoquants up and to the right.

A

True

29
Q

What is Marginal Rate of Technical Substitution? Variable?

A

The amount by which one input can be reduced when one extra unit of another input is used; MRTS

30
Q

Fill in blank. The absolute value of the _______ of the isoquant tells you the MRTS

A

slope

31
Q

True or false. The isoquant gets flatter at higher levels of labor.

A

True

32
Q

What is the Fixed-Proportions Production Function?

A

A production function with L-Shaped isoquants. MRTS is either infinite or zero

33
Q

What is the Perfect Substitutes Production Function?

A

production function where the MRTS is constant at all points. Isoquants are linear.

34
Q

What is individual demand curve?

A

A curve that relates the price of Good X to the quantity of Good X that a consumer will buy holding all other factors constant

35
Q

What does lowercase ‘q’ refer to?

A

an individual’s quantity demanded

36
Q

What does uppercase ‘Q’ refer to?

A

market quantity demanded

37
Q

What is horizontal summation?

A

a process which adds the quantities demanded by individuals (q) for a given price to get the market quantity(Q) for that price

38
Q

True or false; The number of kinks is one less than the number of unique choke prices

A

true

39
Q

What is consumer surplus?

A

the price that a customer is willing to pay for a good minus what the consumer actually pays for it
