Or better said, did some austrian economists ever try to stablish some way to quantify value mathematically?
A marxist once told that a branch of the marginalists tried to do it but I was quite sceptic.
I know Mises discarded the idea out of hand.
Probably Jevons or Walras but they are not Austrian. The Austrian formulation of MU differs from theirs even if subtly, and you’ll see this if you read Menger’s Principles.
