25
If Ei > 0 what kind of goods is the product?
Normal Goods
26
If Ei < 0 what kind of goods is the product?
Inferior Goods
27
What is Price Elasticity of Supply?
Responsiveness of Qs to a change in price of the same product.
28
If % ^ of Qs > % ^ of P then?
Supply is elastic and Es > 1
29
If % ^ of Qs < % ^ of P then?
Supply is inelastic and Es < 1
30
If % ^ of Qs = % ^ of P then?
Supply is Unitary elastic and Es = 1
31
What is the main Determinant of Supply?
Time (The more time the more elastic)
32
Look at Elasticity of Tax Incidence
Look at Elasticity of Tax Incidence
33
What is Marginal Utility?
The additional satisfaction of consuming 1 more unit of a product?
34
The more tacos you eat what happens to Marginal Utility?
Marginal Utility will gradually go up until it hits a point where its no longer satisfying to eat more tacos and it will begin to go back down?
35
Why should consumers allocate their income?
So that the last dollar spent can yield the same level utility.

37
What causes a negative slope of the individual demand curve?
-Substitution effect -Income -Law of diminishing MU
38
If Price goes down what happens to purchasing power of Income?
Purchasing power of income goes UP
39
What is a firm?
A institution that hires factors of production to produce various goods and services?
40
What is a plant?
A physical facility such as a factory that is used to produce and distribute goods.
41
What is a industry?
A group of firms that produce similar products.
42
What is economic cost?
The value of input to produce output
43
What determines the amount of goods and services that producers are willing to produce?
It depends on the price of product and the cost of production
44
What are the two different types of costs when it comes to Economic cost?
Explicit cost Implicit cost
45
What is explicit cost?
The payments by the firm to outsiders such as raw materials and wages
46
What is implicit cost?
The opportunity cost of a firm using resources in producing output
47
Accounting profit = ?
Total Revenue - Explicit Cost
48
Economic Profit = ?
Total Revenue - (Explicit = Implicit cost including a normal profit)
49
What does Short Run mean?
Short run is a time frame where there are some fixed features of production and a time that not long enough for a firm to change the planned capacity.
50
What does Long Run mean?
Long run is a time frame where all factors of production are a variable
51
What is the variable factor?
Labour
52
What is Total Product (TP)
All output that could be produced but all units of input during given time
53
What is Average product (AP)
How much output on average is being produced per unit of input
54
How do you calculate AP
TP / Labour
55
What is Marginal Product (MP)
The additional units of output that are produced by one more unit of input
56
How do you calculate MP
Change in TP / Change in labour
57
What happens to AP when MP is higher than it?
MP pulls AP up
58
What happens to AP when MP is lower than it?
MP pulls AP down
59
What is the Law of Diminishing Marginal Product?
As more units of a variable factor are added to fix factors of production (land and capital) after a certain point Marginal product of the variable factor diminishes because each additional edition of the variable factor will have smaller and smaller units of the fixed factor.
60
What are the two types of Total cost?
Total fixed cost Total variable cost
61
What is total fixed cost?
The cost that fixed regardless of the level of output
62
What is total variable cost?
The cost that increases as production increases
63

LOOK AT GRAPHS ABOUT TC, TVC and TFC
64
What is Marginal Cost?
Additional cost of producing one more unit of output
65
Marginal Cost cuts both ATC and AVC where?
At their minimum point
66
MP and MC do what in their graph forms?
Mirror each other (Refer to Notes)
67
What happens to firm in Long Run?
Firms will adjust factors of output to maximize production
68
The long run cost curve is a envelope of what?
Short Run average total cost curves
69
What happens the minimum point of ATC in Long run
A new firm is added
70
What happens in the Economies of scale state in the long run AC curve?
% ^ in output > % ^ in input
71
What happens in the Diseconomies of scale state in the long run AC curve?
% ^ in output < % ^ in input
72
Economies of scale happens when?
When the AC is decreasing as output is increasing
73
What are some factors that explain economies of scale?
Division of Labor Specialization Managerial specialization Use of efficient capital Research, development and advertising
74
What is constant return to scale?
% ^ in output = % ^ in input
