Aswath Damodaran – Session 4: Closing The Books On The Objective Function & Opening The One On RiskVW Staff
The objective function matters, and there are no perfect objectives. That is the message of the last two classes. Once you have absorbed that, I am willing to accept the fact that you still don’t quite buy into the “maximize value” objective. That is fine and I would like you to keep thinking about a better alternative with three caveats. First, you cannot cop out and give me multiple objectives – I too would like to maximize stockholder wealth, maximize customer satisfaction, maximize social welfare and employee benefits at the same time but it is just not doable. Second, your objective function has to be measurable. In other words, if you define your objective as maximizing the social good, how would you measure social good? Third, take your objective (and the measurement device you have developed) and ask yourself a cynical question: How might managers game this system for maximum benefit, while hurting you as an owner? In the long term, you may almost guarantee that this will happen. In the last part of the class, I defined risk and started on what goes into a good risk and return model.
