Hi Axel:
I think you should have offered a prize to the HESer who gets the
right answer! Nevertheless, you attracted many competitors.
If you are truly interested in the subject, you might want to know
about the people who used the term "utility" without the adjective
"marginal." Here is the result of Murray Rothbard's research on the
issue. I wonder also whether the Islamic "economists" had something
to say about this.
