This is: To find the optimal cost of producing an arbitrary output level in terms of to get: we would substitute expressions for optimal and 33 ECO 204 Chapter 12: a Firm’s Cost Minimization Problem (this version 2012-2013) University of Toronto, Department of Economics (STG). ECO 204, S. Ajaz Hussain. Do not distribute. () ⏟ Here () [[ ] [[ ] is a constant. As long as we remember that this is the lowest cost of producing an arbitrary output we will sometimes write the cost function as ( ) from any of the FOC; for example, from the labor FOC we have: [⏟ [ . Finally we can solve for This implies that: () ( ) ( ) From our discussion of the general long run CMP we know that if we want the change in parameter that we can use the envelope theorem on: ⏟{ } ( Denote [ due to a small change in the ) and we get: Since we know the cost function we can easily derive the and from this : 34 ECO 204 Chapter 12: a Firm’s Cost Minimization Problem (this version 2012-2013) University of Toronto, Department of Economics (STG).
