Homework 3: Cost Theory
Learning Objective: This homework will enable you to understand, Producer Behavior Theory (decision making principles of producers), based on Cost Theory and the derivation of a producer’s supply function.
Please contact MS. Amani Al Alawi for clarifications on the homework.
- The figure given below depicts cost functions of a farm producing onions. Use the information in the figure to answer the following questions.
- If the price of Onion was 10 OR/Unit, what would be the quantity of onions supplied by the farm?
- Estimate the following for the production quantity that would be supplied when the price of Onion is 10 OR/Unit.
- Average Total Cost (ATC)
- Average Variable Cost (AVC)
- Total Cost (TC)
- Total Variable Cost (TVC)
- Total Return (TR)
- Profit or Loss
- At what price of onion will the farm “close down”?
- At what output of onion will the farm “close down”?
- Estimate the following at the “closing down” output of the farm.
- Average Total Cost (ATC)
- Average Variable Cost (AVC)
- Total Cost (TC)
- Total Variable Cost (TVC)
- Total Return (TR)
- Profit or Loss
- Define the supply curve of a firm in relation to the cost curves.
- Consider Total Cost (TC) as composed of Total Fixed Cost (TFC) and Total Variable Cost (TVC) and write formula for the following.
- TC
- TFC
- TVC
- AVC
- AFC
- ATC
- MC
- Use the above formula and fill in the missing cells in the following table 2.2.
Table 2.2. Cost data on tomato production using the variable input fertilizer.
X | Y | Price X | TFC | TVC | TC | MC | ATC | AVC | AFC |
2 | 40 | 5 | 110 | ||||||
65 | 0.4 | ||||||||
80 | 0.375 | ||||||||
90 | 150 | ||||||||
Note: | X is quantity of fertilizer (Units) | ||||||||
Y is quantity of Tomato (Units) | |||||||||
Price of X is the price of fertilizer (OR/ Unit) |
- Using the information calculated in table 2.2., estimate the profit (or loss) of production for price of Tomato as 0.40 (OR/Unit) in the Longrun and Shortrun.
