Costs Flashcards
Define and give the formula of: Total Costs
The cost of producing a given level of output
Total Fixed costs + Total Variable Costs
Define and give the formula of: Total and Average Fixed Costs
Total and Average Variable Costs
(give examples where necessary)
TFC- costs that don’t vary with output (e.g. rent,salaries,capital)
AFC= TFC/Output
TVC- costs that vary with output (e.g. raw materials, wages)
AVC= TVC/Output
Define and give the formula of:
Marginal Costs
The additional cost of producing one extra good/service
change in total costs/change in output
Go on sketchpad and Draw on one curve:
MC
ATC
AVC
AFC
Did you remember:
-Nike tick shaped MC curve
-AFC is always falling
-AVC is u-shaped and intersects MC at its lowest point
-ATC is the same shape as AVC but slightly higher and intersects MC at its lowest point
Name and explain the reason why the MC is shaped like that
The Law of Diminishing Marginal Productivity:
-In the SHORT RUN only
-When you initially increase factor inputs, productivity will increase due to specialisation, initially decreasing MC
-Due to one factor of production being fixed, adding more factor inputs will lead to a decrease in productivity, which will increase MC
Go on sketchpad and Draw on one curve:
LRAC
Multiple SRAC curves
Region of the graph with
-Economies of scale
-Diseconomies of scale
-Constant Returns to scale
-Minimum efficient scale
Did you do:
-One large LRAC
-Many SRAC within the LRAC
-Economies of scale when LRAC is decreasing as output increases
-Constant returns to scale when LRAC is constant as output increases
-Diseconomies of scale when LRAC is increasing as output increases
-Minimum efficient scale when LRAC first hits its lowest
