  2. Less than 85%, your average will ___
  3. Equal to 85%, your average will ___
A
  1. Rise
  2. Fall
  3. Remain Constant

25
If your MPvL = APvL then APvL
Remains Constant (doesn't change)
26
Slope of a line from the origin to any point on the Total Point Curve
Average Product of Labor (APvL)
27
Slope of the line tangent to any corresponding point on the Total Product Curve
Marginal Product of Labor (MPvL)
28
When MPvL = ___ , the total production is at a maximum
0
29
Maximum MPvL occurs where total production is (steeper/flatter)
steeper (at the highest point on the curve before it declines)
30
Whats the formula for MPvL?
dQ/dL
31
As the use of an input increases with other inputs fixed, the resulting additions to output will eventually decrease
Diminishing Marginal Returns
32
When the use of labor is (small/large) and capital is (variable/fixed), output increases considerably since workers begin to specialize
Small | Fixed
33
Initially, MPvL (increases/decreases)
Increases
34
Assign Tasks
Specialization (ex. one person sews a shirt and the other person irons on a logo)
35
When the use of labor input is (large/small), some workers become less efficient
Large
36
Eventually, MPvL (increases/decreases)
Decreases (diminishes)
37
Why does MPvL eventually decrease (diminish) when labor input is large?
1. Crowding of Fixed Inputs (fixed number of machines and factory size) 2. Socialization (amount of talking is directly proportional to the number of workers and increases with each additional worker)
38
If there are 20 machines, the MP of the 21st worker is (more/less) than the 20th worker
Less because the 21st worker will have to share a machine and of course higher levels of crowding/socialization
39
There are 20 machines in a factory. At what point do the negative impacts of crowding and socialization outweigh the benefits of specialization?
Anywhere after L=1 and Before L = 21
40
Changes in technology will cause shifts in the ___ ___ ___
Total Production Curve
41
Can labor productivity increase if there are improvements in technology
Yes, even though any given production process exhibits demising returns to labor
42
Has two variable inputs (Labor and Capital)
Long Run Production
43
What two things must a firm meet for technologically efficient production?
1. Choose the technology that uses smallest possible quantities of inputs to produce a given level of output 2. Choose the technology that produces the most output from given quantities of inputs K&L
44
Curve that shows all technologically efficient combinations of labor and capital that can produce a single (iso) level of output (quantity)
Isoquant
45
If labor > capital, does that mean that the company is technologically inefficient?
No. It can still be efficient (things can be done by hand or machines can run 24/7 unlike employees) - only technologically inefficient if: 1. K=6 and L=6 and Q=20 2. K=6 and L=8 and Q=20 INEFFICIENT (more L for same Q)
46
What is the biggest difference between Isoquant and Indifference Curves?
Isoquants hold something measurable (quantity) constant | Indifference Curves hold something that is not measurable (utility) constant
47
Isoquants farther from the origin represent (greater, less) levels of output
Greater (quantity is higher)
48
Isoquants (do/don't) cross
Don't (if they do that means one is inefficient) ex. L=20 and K=10 and Q=30 L=20 and K=10 and Q=20 INEFFICIENT
49
Isoquants slope (up/down)
Down (if they slope up then one is inefficient) ex. L=20 and K=10 and Q=30 L=30 and K=20 and Q=30 INEFFICIENT
50
Slope of the isoquant
Marginal Rate of Technical Substitution (MRTS)
51
Units of K (input in the vertical axis) that can be replaced with an additional unit of L (input on the horizontal axis), keeping the output constant
Marginal Rate of Technical Substitution (MRTS)
52
The slope of the isoquant (MRTS) becomes ___ as more K is replaced by L
Flatter
53
Change in Q resulting from using one extra unit of L, holding all other factors (K) constant
MPvL
54
Change in Q resulting from using one extra unit of K, holding all other factors (L) constant
MPvK
55
Whats the formula for Marginal Product of Capital?
dQ/dK
56
Isoquants are (convex/concave)
Convex - implied because diminishing MRTS occurs because of DMR
57
Replacements value of L in terms of K falls (an additional unit of L replaces fewer and fewer units of K)
Diminishing Marginal Rate of Technological Substitution (DMRTS)
58
when L goes up, MPvL goes (up/down)
Down because each additional worker is less useful
59
when K goes down, MPvK goes (up/down)
Up because each remaining piece of capital is more useful
60
Straight line isoquant, constant MPs and MRTS
Perfect Substitutes
61
MPs=0, MRTS=0/∞, L-shaped
Perfect Complements (no substitution available; cannot increase output unless K and L are both increased in that specific proportion)
62
Linear production function means perfect ___
Perfect Substitute
63
Fixed proportions production function means perfect ___
Perfect Complements
64
How does a firm decide, in the long run, the best way to increase output?
Returns to Scale
65
Rate at which output increases as inputs are increased proportionately
Returns to Scale
66
Output more than doubles when all inputs are doubled
Increasing Returns to Scale (IRS)
67
Larger output associated with lower average cost (ex. auto manufacturing)
Increasing Returns to Scale (IRS)
68
One firm is more efficient than many (ex. electric utilities)
Increasing Returns to Scale (IRS)
69
The isoquants get closer together
Increasing Returns to Scale (IRS)
70
Output doubles when all inputs are doubled
Constant Returns to Scale (CRS)
71
Size does not affect productivity
Constant Returns to Scale (CRS)
72
May have a large number of producers
Constant Returns to Scale (CRS)
73
Isoquants are equidistant
Constant Returns to Scale (CRS)

Output less than doubles when all inputs are doubled
Decreasing Returns to Scale (DRS)
75
Decreasing efficiency with large size
Decreasing Returns to Scale (DRS)
76
Reduction of entrepreneurial abilities
Decreasing Returns to Scale (DRS)
