This begs the question: what is the breakeven number of commercial hours? For PDS this is a cumbersome calculation because it has two types of customers: commercial and intercompany. Before doing breakeven calculations for two “divisions” let’s do it for one “division” (the standard approach shown in most accounting and finance courses). 33 ECO 204 Chapter 13: The Short Run Cost Minimization Problem (this version 2012-2013) University of Toronto, Department of Economics (STG). ECO 204, S. Ajaz Hussain. Do not distribute. Let us solve this problem by first assuming PDS only serves commercial customers (not commercial and intercompany customers), has a linear cost function, and has ample capacity. In this case profits are: By definition: Substitute this back in: ( ) ) is known as the contribution margin (what an additional unit of output contributes to profits). At The term ( the breakeven output profits are zero so that: ( If the cost function is linear then ) is a constant so that: ( Notice that if then and if ( the number canbe negative (if ) ) then . It’s conceivable that in the formula above ) To accommodate this possibility: ( ) This formula assumes that the company has ample capacity. With a finite capacity, the breakeven output will be (make sure you understand this): ( ( ) ) _____________________________________________________________________________________ _____________ Example: Suppose a company has the following cost function (notice it’s linear, so that the company has constant returns): Observe that 34 ECO 204 Chapter 13: The Short Run Cost Minimization Problem (this version 2012-2013) University of Toronto, Department of Economics (STG). ECO 204, S. Ajaz Hussain. Do not distribute. Currently, . What is the breakeven quantity? From above: Now suppose the cost function becomes: Fixed cost has increased by $1,000. Now, the breakeven quantity is: Since price and were constant, the company has to sell more units to cover the higher fixed costs. __________________________________________________________________________________________________ Let us now compute the PDS’s commercial breakeven quantity: Breakeven Output Requires: () () With constant returns we can solve for breakeven output analytically: By definition: ⏟ ⏟ { } To accommodate the possibility that this number can be negative and that there may be a finite capacity, the formula becomes: ( { ( ) } ) 35 ECO 204 Chapter 13: The Short Run Cost Minimization Problem (this version 2012-2013) University of Toronto, Department of Economics (STG).

From the case recall that intercompany revenue is capped at $82,000/month and that intercompany data services price is /hour, intercompany hours are capped at an average of: hours per month Comme...
