Studying average and total cost curves

Problem:

a.Given the following chart and information fill in the missing values.

Output TFC TVC TC MC AFC AVC ATC
0 $2,000 --
50 100
100 80
150 60
200 50
250 60
300 85
350 125

b. Please graph your results. Draw both the average and total cases making sure to explain these important relationships or trends in the curves:

In the AVG Cost Curves:
i) Shape of AVC as Q increase
ii) AVC and ATC and Q increases
iii) U-shape of AVC and ATC

In Total Cost Curves
i) Shape of TFC, TVC/TC
ii) TC and TVC as Q increases (note: TC = TVC + TFC  this tells you something about distance between the two curves)

c. In a typical LRAC curve like the illustration below, explain economies and diseconomies of scales as well as constant returns to scale. Make sure to use the graph and explain the concept.

1) TFC - It will remain $2000 for all production ...

Solution Summary

Solution explains the formulas for calculating TFC, TVC, TC, MC, AFC, AVC and ATC. It also explains the shape and behavior of average and total cost curves. Economies/diseconomies/constant economies are also explained for long run average cost curve (LRAC).
