Firms face different costs in the short-run depending on their level of output. Total costs include total fixed costs, which do not vary with output, and total variable costs, which do vary with output. As a firm's output increases, average fixed costs decline due to spreading fixed costs over more units of output. Average variable costs and average total costs initially decline as well, but eventually increase once diminishing returns set in and marginal costs rise. Understanding how costs change with output helps firms maximize profits in the short-run.

Monopolistic competition - The Four Types of Market Structure - EconomicsFaHaD .H. NooR
Monopolistic competition is a type of imperfect competition such that many producers sell products that are differentiated from one another (e.g. by branding or quality) and hence are not perfect substitutes. In monopolistic competition, a firm takes the prices charged by its rivals as given and ignores the impact of its own prices on the prices of other firms.[1][2] In the presence of coercive government, monopolistic competition will fall into government-granted monopoly. Unlike perfect competition, the firm maintains spare capacity. Models of monopolistic competition are often used to model industries. Textbook examples of industries with market structures similar to monopolistic competition include restaurants, cereal, clothing, shoes, and service industries in large cities. The "founding father" of the theory of monopolistic competition is Edward Hastings Chamberlin, who wrote a pioneering book on the subject, Theory of Monopolistic Competition (1933).[3] Joan Robinson published a book The Economics of Imperfect Competition with a comparable theme of distinguishing perfect from imperfect competition.
Monopolistically competitive markets have the following characteristics:
There are many producers and many consumers in the market, and no business has total control over the market price.
Consumers perceive that there are non-price differences among the competitors' products.
There are few barriers to entry and exit.[4]
Producers have a degree of control over price.

What is 'Monopolistic Competition'
Characterizes an industry in which many firms offer products or services that are similar, but not perfect substitutes. Barriers to entry and exit in the industry are low, and the decisions of any one firm do not directly affect those of its competitors. All firms have the same, relatively low degree of market power; they are all price makers. In the long run, demand is highly elastic, meaning that it is sensitive to price changes. In the short run, economic profit is positive, but it approaches zero in the long run. Firms in monopolistic competition tend to advertise heavily.
BREAKING DOWN 'Monopolistic Competition'
Monopolistic competition is a middle ground between monopoly, on the one hand, and perfect competition (a purely theoretical state), on the other, and combines elements of each. It is a form of competition that characterizes a number of industries that are familiar to consumers in their day-to-day lives. Examples include restaurants, hair salons, clothing and consumer electronics. To illustrate the characteristics of monopolistic competition, we'll use the example of household cleaning products.
Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

6. Costs of Production
Big Ideas
Important questions:
1) What is productivity and how does it change as resources
(LAND, LABOR, CAPITAL) are added to production?
2) What are the different costs faced by firms in the short-run and
the long-run?
3) What is the relationship between the productivity of its
resources and the costs faced by a firm?
4) Why does understanding productivity and costs matter to firms?
Discussion Question: What is productivity, and why
do firms care about it?
Blog posts: "Productivity"
7. Costs of Production
Law of Diminishing Returns
Understanding Productivity:
Productivity (OUTPUT) : The amount of output attributable to a unit of
input. Examples of productivity:
"Better training has increased the productivity of workers"
"The new robot is more productive than older versions"
"Adding fertilizer has increased the productivity of farmland"
Total prod. (TP or TO) is the total output of a particular firm
Example of TP: "After hiring more workers the firm's total product
increased."
Marginal prod. of labor (MPL) is the change in total product resulting from each
additional worker.
>>MPL = ∆TP/∆L
Average prod. of labor (APL) is the output, on average, by each
worker
>>APL = TP/units of L
8. Costs of Production
Law of Diminishing Returns
Law of Diminishing Returns:states that as additional units of a variable resource
are added to fixed resources, beyond some point the marginal product of the
variable resource will decline.
HUH? Let's illustrate this with an example
Example: Paper Chain Factory
Instructions:
1) Use inputs (land, labor and capital) to create a product (paper chains)
2) Labor is the only variable resource. Land and capital are fixed.
3) Production rounds last one minute
4) Record production data in a data table

Productivity and costs
Productivity and Costs: As worker productivity increases, firms get "more for
their money", meaning per-unit and marginal costs decrease. When productivity
decreases, costs increase.
Discussion: When productivity of workers is
Costs and Productivity rising, firms costs are falling, since they're
getting more output for workers while paying

Summary: Increasing marginal returns is reflected in a declining marginal cost, and
diminishing marginal returns in a rising marginal cost!
15. Costs of Production
Short-run Costs of Production
What is the short-run? "the fixed-plant period"
The short-run is the period of time over which a firm's plant size is fixed.
Capital cannot and land cannot be varied, labor is the only variable
resource. To increase output in the short-run, a firm can only increase
inputs of labor, not the other resources.
Total Costs:
Total fixed costs (TFC): These are the costs a firm faces that do not
vary with changes in short-run output. Could include rent on factory
space, interest on capital (already acquired).
Total variable costs (TVC): These are the costs a firm faces which
change with the level of output in the short-run. Could include
payment for raw materials, fuel, power, transportation services,
wages for workers, etc...
Total cost:TFC + TVC at each level of output
16. Costs of Production
Short-run Costs of Production
Resource costs in the short-run:
Rent - the payment for land: Rent is fixed in the short-run since firms cannot add this
resource to production. Rents must be paid regardless of the level of the firm's output.
Interest - the payment for capital: Interest is fixed in the short-run since firms cannot
add this resource to production. Interest must be paid on loans regardless of the level of
the firm's output.
Wages - the payment for labor: Wages are variable in the short-run, since firms can hire
or fire workers to use existing land and capital resources. Wage costs increase when new
workers are hired, and decrease when workers are laid off.
Normal profit:the minimum level of profit needed just to keep an entrepreneur operating
in his current market. If he does not earn normal profit, an entrepreneur will direct his skills
towards another market. Normal profit is a cost because if a firm does not earn normal
profit, it is not covering its costs and may shut down.
Other short-run variable costs of production:
·Transportation costs: Firms pay lower transport costs at lower levels of output.
·Raw material costs: vary with the level of output
·Manufactured inputs: fewer parts are needed from suppliers when a firm lowers output.
17. Costs of Production
Short-run Costs of Production
Graphing total costs:
TFC: Notice that regardless of the level of output, TFC remains constant. This is because these
are costs that do not vary with output.
TVC: Notice that when output is zero, TVC is zero, because you do not need to hire any workers
or use any raw materials if you're not producing anything. As output increases, TVC continues to
increase
TC: Notice that when output is zero, TC = TFC. But once the factory begins pumping out products,
TC rises with TVC. TC is the sum of TFC and TVC, since both fixed and variable costs make up
total cost.
TC
Diminishing returns:

(The firm gets "less for its money")
18. Costs of Production
Short-run Costs of Production
Average Costs:
Average fixed cost:AFC=TFC/Q
AFC will decline as output rises, never increases. This is because the fixed cost
(which never goes up) is “spread out” as output goes up. This is called “spreading
the overhead”
Average variable cost:AVC = TVC/Q
For simplicity, we will assume that labor is the only variable input, the labor cost per
unit of output is the AVC
Average total cost:ATC = TC/Q
Sometimes called unit cost or per unit cost. ATC also equals AFC + AVC
Marginal Cost = the additional cost of producing one more unit of
output.
MC = ∆TVC/∆Q.

20. Costs of Production
Short-run Costs of Production
Graphing Average and Marginal Costs:
AFC: it declines as output increases. This is called "spreading the overhead".
ATC and AVC: At first they are declining as output increases. This is during the stage when MP is
increasing, since new labor is making better use of capital and beginning to specialize.
AVC: When AVC is at its minimum, average product is at its maximum, meaning workers are producing
the most output per worker. As more workers are added, average product begins to go down, and AVC
begins to rise.
Costs
Short-run Costs Things to notice:
·the vertical distance between ATC and
AVC equals the AFC at each level of
MC output.
ATC
·MC intersects both AVC and ATC at their
minimum. This is because if the last unit

then the average must be falling, and vis

24. Costs of Production
Short-run vs. Long-run costs
Long-run is the variable plant period, meaning that firms can open up new plants, add
capital to existing plants, or close plans and remove capital if need be.
Economies of scale: are the cost advantages that a business obtains due to
expansion. As new plants open, ATC declines. WHY?
·better specialization, division of labor, bulk buying, lower interest on loans,
lower per unit transport costs, larger and more efficient machines, etc...
Also called "Increasing returns to scale"
Minimum Efficient Scale (MES): The minimum level of output a firm must
achieve to achieve the lowest average total cost.
Diseconomies of Scale: When a firm becomes "too big for its own good" it
experiences diseconomies of scale. Continuing to add plants and increase output
causes ATC to rise. WHY? Mostly due to control and communications problems,
trying to coordinate production across a wide geographic area may make firm less
efficient.
Also called "Decreasing returns to scale"
