3. CHAPTER 5: BACKGROUND OF SUPPLY
Introduction
TOPIC
Firms wants to increase output in hurry, it will only be able to increase the
quantity of certain inputs. It can use more raw materials, more fuel, more tools
and possibly more labors.
These can be differentiate between fixed factors and variable factors.
What is fixed factors?
An input that cannot be increased in supply within a given time period.
What is variable factors?
An input that can be increased in supply within a given time period.
Short Run Long Run

4. CHAPTER 5: BACKGROUND OF SUPPLY
Short Run Vs Long Run
TOPIC
What is short run?
The period of time over which at least one factor is fixed. Example: renting
on land is fixed.
What is long run?
The period of time long enough for all factors to be varied. Example: the
cost of raw material is various.
A firm’s cost of production will depend on the factors of production it uses. The
more factors it uses, the greater its costs will be. This relationship depends on
two elements:
1. The productivity of the factors – the greater their productivity, the
smaller will be the quantity of them that is needed to produce.
2. The price of the factors – the higher their price, the higher will be the
costs of production.

Total Cost (TC)
TOPIC
Total Cost (TC) of production is the sum of the total variable costs (TVC) and
the total fixed cost (TFC) of production.
TC = TVC + TFC
Fixed Cost (FC) = Total costs that do not vary with the amount of output
produced.
Variable Cost (VC) = Total costs that do vary with the amount of output
produced.

9. CHAPTER 5: BACKGROUND OF SUPPLY
Average and Marginal Cost
TOPIC
In addition to total costs (TC, TFC, and TVC), there are two other categories of
costs that we will be using. There are average cost and marginal cost.
Average cost (AC) is cost per unit of production:
AC = TC / Q
Example : If it costs a firm $2000 to produce 100 units of a product, the average
cost would be $20 for each unit ($2000/100).
Like Total cost, average cost can be divided into the two components, fixed and
variable. In other words, average cost equals average fixed cost (AFC = TFC/Q)
plus average variable cost (AVC=TVC/Q)
AC = AFC + AVC

10. CHAPTER 5: BACKGROUND OF SUPPLY
Marginal Cost (MC)
TOPIC
Marginal cost (MC) is the extra cost of producing one more unit: that is, the rise
in total cost per one unit rise in output.
MC = TC
Q
Example: A firm is currently producing 1000000 boxes of matches a month. It
now increases output by 1000 boxes (another batch): Q =1000. Assume that,
as a result, total costs rise by $40: TC =$40. What is the cost of producing
one more box of matches? It is:
MC = TC = $40 = 4c
Q 1000
