Question

Describe various types of production costs.

Answer 1

1. Fixed Costs

   • These are costs that do not change with the level of output.
   • Incurred even when production is zero.
   • Examples: Rent, insurance, salaries of permanent staff.
   • Exist only in the short run.
2. Variable Costs:
   • These change directly with the level of output.
   • Zero when production is zero and increases as output rises.
   • Examples: Raw materials, electricity, wages of temporary labour.
3. Total Cost (TC):
   • The sum of fixed and variable costs at each level of output.
   • TC = TFC + TVC
4. Average Cost (AC)
   • Cost per unit of output.
   • AC = `(TC)/Q`
5. Average Fixed Cost (AFC):
   • Fixed cost per unit of output.
   • AFC = `(TFC)/Q`
   • Decreases as output increases.
6. Average Variable Cost (AVC):
   • Variable cost per unit of output.
   • AVC = `(TVC)/Q`
7. Marginal Cost (MC): 
   • The additional cost of producing one more unit of output.
   • MC = `(TC)/Q`
   • Derived mainly from changes in variable costs.

8. Opportunity Cost

   • The value of the next best alternative foregone.
   • Important in decision-making and resource allocation.
