Some economists point out, that
evaluations deal with values. And values should be quantified
in terms of currency,
so that the easiest end is to add all values… That amounts to transfer any assessments to Euros or dollars. There are some models to do this in a
fairly scientific way.
Taking an example, we must invent some
estimated figures. If those are accepted, then option 3 is best, and option 2
seems to be surprisingly good, too. But in some cases, we pass the limits of
fairness and modesty. How to calculate the value of human health? …or of
eco-efficiency? So, for as attractive this idea may
sound, in practice it generates significant controversies.
