### BAEB602 Chapter 5: Background of Suppply (part 2)

1. 1. BAEB602 MICROECONOMICS CHAPTER 5 BACKGROUND OF SUPPLYPREPARED BY:Nur Suhaili RamliSchool of Marketing andEntrepreneurship (SoME)FACULTY OF BUSINESS AND MANAGEMENT
2. 2. CHAPTER 5: BACKGROUND OF SUPPLYObjectives TOPIC  To identify short-run costs  To identify long-run costs  To understand the various of costs  To apply theories in case study Slide 2 of 17
3. 3. CHAPTER 5: BACKGROUND OF SUPPLYIntroduction 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 Slide 3 of 17
4. 4. CHAPTER 5: BACKGROUND OF SUPPLYShort 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. Slide 4 of 17
5. 5. CHAPTER 5: BACKGROUND OF SUPPLYTotal 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. Slide 5 of 17

9. 9. CHAPTER 5: BACKGROUND OF SUPPLYAverage 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 Slide 9 of 17
10. 10. CHAPTER 5: BACKGROUND OF SUPPLYMarginal 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 Slide 10 of 17
