Firms seek to maximize profits

A

Q

Variable costs

A

The cost of variable inputs

36
Q

Total cost

A

Is the sum of fixed and variable cost

37
Q

How do you economists divide time

A

Economists divide time into 2 periods
Short run
Long run

38
Q

In the short run

A

The business has both fixed and variable costs and fixed and variable inputs

39
Q

In the long run

A

The business has only variable costs

40
Q

How does the long run in a business appear

A

The long run appears in short burst. For example when its lease expires, the brief period (perhaps just a few minutes )until the business signs a new one, moves or shuts down

41
Q

Average cost

A

Is the cost per unit

42
Q

When is the ability of a business to adapt to changing market conditions greater

A

When more of the cost and inputs are variable , which means that they are more able to adjust the longer the amount of time available to them

43
Q

Diminishing returns

A

Diminishing returns occurs when the addition of units of one input results in decreasing amount of additional output being produced

44
Q

What is the best way for a business to control costs

A

To add more of all the factors of production when it wants to expand. ( labor, capital, and natural resources)

45
Q

Marginal productivity

A

How much more output is added with one more worker

46
Q

Marginal physical productivity MPP

A

Additional output produced by an additional unit of labor which equals the change in total output divided by the change in labor

47
Q

What is the problem with workers and their MPP marginal physical productivity

A

As we add labor without adding capital, the marginal productivity of the new workers will decline

48
Q

Marginal cost MC

A

Is the additional cost of producing one more unit of good

49
Q

What is the key to determining the most profitable quantity of a good that a firm can produce

A

Marginal cost

50
Q

Average cost

A

Average cost= total cost divided by the total number of goods produced

51
Q

Marginal cost

A

Is the additional cost of the last product produced which includes only those factors that vary :labor and natural resources

52
Q

The marginal cost will either be

A

Higher or lower than the average cost

53
Q

Marginal cost comes entirely from

A

Variable cost

54
Q

There is no relationship between fixed cost and

A

Marginal cost

55
Q

Marginal cost will tell us whether

A

Each unit of production adds to our profit or not.

56
Q

Why is average cost needed

A

Average cost is needed to discover whether or not the entire business is profitable, since average cost include fixed cost

57
Q

The independent nature of marginal cost and fixed cost also tells us that

A

Businesses with the same total cost may act differently if their fixed variable costs are not the same

58
Q

How to calculate average fixed cost

A

Average fixed cost equals fixed cost divided by the quantity we produce

59
Q

How to calculate average total cost ATC or total cost per unit?

A

Total cost divided by the quantity produced

60
Q

Because of diminishing returns, average total cost will

A

Decline at first, but eventually it will cost us more and more to produce more and more because the new workers we hire are not as productive as our existing workers

61
Q

Similarly because of diminishing returns, our marginal cost (cost of producing one more)

A

Declines initially, but eventually turns and heads up as diminishing returns sets in

62
Q

Why does the marginal cost always pass through the lowest point on the average total cost

A

Because the average total cost follows what the marginal cost tells it to do.
When the marginal cost is below the average total cost, average total cost falls [heads towards marginal cost )
When marginal cost is above the average total cost, average total cost rises [heads towards marginal cost]
Where the average total cost switches from falling to rising, therefore, must be where marginal cost is not above, nor below, average total cost, which means they are equal

63
Q

Sunk cost

A

Sunk cost are on the cost that we have already paid out. They could have been fixed or variable cost originally, but in either case ,they are gone

64
Q

Variable costs once paid

A

Cannot be reclaimed

65
Q

If a business is losing money, the decision to shut down is best based on

A

The comparison between the loss it incurs by operating and the loss it would incur if it shut down

66
Q

If a business operates

A

It has revenue, fixed cost and variable cost

67
Q

Loss of a operating business is equal to

A

It’s revenue minus the sum of its fixed and variable costs

68
Q

The loss of a closed business is equal to

A

It’s fixed cost, since it has no revenue and zero variable cost

69
Q

Should some businesses be able to operate forever at a loss

A

No, in the long run, there are only variable cost. So a business must be profitable in the long run or it will have to shut down.
-businesses can operate at a loss for a short period, but eventually the value of its fixed costs diminishes to the point that shutting down is the most sensible decision

70
Q

The long run

A

Is the point when all costs are variable

71
Q

The long run shows up in

A

Spurts: when the lease expires, when we decide to open a new store, or when we make any decision that changes all the factors of production at the same time

72
Q

Long run decisions mean

A

Flexibility in all facets of operation.

73
Q

Short run decisions

A

Are constrained by fixed inputs and costs

74
Q

The short run and a long run happen

A

At the same time. Because we are running our business today in the short run, while planning and implementing changes for the future, in the long run

75
Q

Optimal business size

A

The optimal or best size for the business is a long run decision

76
Q

Economies of scale

A

Occurs when the cost of production decline with an increase in the size of the firm

77
Q

Diseconomies of scale

A

Occurs when the cost of production increases with the size of the firm.

78
Q

Businesses that have significant economies of scale will tend to

A

Grow larger

79
Q

Businesses with significant diseconomies of scale will

A

Remain small

80
Q

Technically, economies of scale exist when

A

The average total cost of production of a good declines as the quantity produced of the good increases. For example: economies of scale are likely to occur in the production of mass produced goods such as cars, electricity and airplanes

81
Q

Diseconomies of scale exist when

A

The average total cost of production rises as the quantity produced of the goods increases.

82
Q

Diseconomies of scale are most often linked to

A

Difficulties in managing a large enterprise. The larger of the company, the more difficult it is to manage

83
Q

Constant returns to scale

A

Some businesses neither become more efficient nor less efficient as they grow. When this occurs, it is referred to as constant returns to scale.

84
Q

Many companies in the real world have constant returns to scale in their operations because

A

They most often achieve these by replication. That is they expand by duplicating existing plants or stores, and contract by eliminating them.
For example McDonald’s does not expand by adding seats to each restaurant, but it builds or replicates new restaurants

85
Q

Minimum efficient scale

A

For every business there is a minimum size that will be profitable for the company to operate, called the minimum efficient scale.

86
Q

Minimum efficient scale is the

A

Smallest size at which the business can operate efficiently
