healers' contracting styles, HMO's

[Lisa & Ian Murray]

Someone should do a paper on economists' use of "unobservable." It's
the magic residual in the total factor productivity equations; it's
the reason women and blacks are paid less than white guys; it's the
all-purpose defense of the status quo when you can't find any other!

Wasn't unobservable first used by "econ.'s" against KM's LTV when they
crimped it into a theory of prices?
