They appreciate what economists don’t, and that is that all this complexity is faux: value is not made by discounting the future. Value is made by doing the right thing now in the light of the uncertainties that we face which we may not be able to quantify but which we believe to be real. And when economists begin to appreciate that we may get better economics.
Net present value, that discounting, is attempting to work out what value will be created in the future by the actions you take now.
How else should you work out what you should do now other than by trying to work out what value it will produce in the future?
All humans do this too. We don’t have the tonic with that 12 th double gin because of the appalling headaches that too much tonic water causes.
