Only the money budget is numerical. The other two employ a different kind of assessment, but one that we can keep up with quite accurately. My rough-and-ready formula for calculating the overall budget for a negotiation gives “time” a value of x, “energy” 2x, “money” 3x, and “emotion” 4x. Obviously, these are not empirically based numbers. They’re a way to drive home the point of relative importance.
