Calculate the Average Variable Cost Function


Precision Engineering department has collected data on its average costs of production for the past 12 months. The monthly fixed cost is $4000 per month. The AVC and associated output data are presented below:

Month Q     AVC $
Jan 70 375  
Feb     58     540       
Mar      160     450       
Apr      120     255       
May      130     138       
Jun      120     150       
Jul      10     450       
Aug      35     350       
Sep      80     60       
Oct      110     70       
Nov      100     90       
Dec      190     153    

(a) Precision Engineering is a perfectly competitive firm. Based on the information above, explain if AVC suggests the functional form: AVC = a + bQ + cQ2. (Draw a scatter diagram of AVC on Y axis and Q on X axis. Fit the scatter diagram with a 2nd degree polynomial trend line.)  

(b) Run the appropriate regression to calculate the estimated parameters for the empirical cost function AVC = a + bQ + cQ2. Your answer should include regression output from the statistical software.  

(c) Show the level of output at which AVC reach its minimum value, and the minimum value of AVC at its minimum.

(d) Explain the significant point in determining the shut down condition of Precision Engineering department.

(e) Show what is the optimal level of monthly production for Precision Engineering department if the market price of each component is $400 per piece? What is the maximum profit or minimum loss Precision Engineering department can expect to earn?


The question belongs to Statistics and it is about calculating the functional form of AVC or average variable cost for Precision Engineering department. The data from the department has been used for statistical calculations such as calculation of functional form, estimated parameters for empirical cost function, optimal level of monthly production, etc. have been answered in the solution in detail.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
